Buyer’s Tips for Purchasing a Car Bottom Furnace

Before you begin shopping around for a Car Bottom Furnace there are a few requirements that you will need to figure out before you start the process.  Here are some tips to that will help determine the type of Car Bottom Furnace that will suit your needs best.

What is the typical Temperature Uniformity needed in my Car Bottom Furnace?  These Furnaces typically operate at about plus or – 25 deg. F uniformity depending on the maximum temperature.  A Car Bottom Furnace can also achieve tighter uniformity (+ or – 10 degrees F), but the engineering must be precise. Typical temperatures are around 1350 deg. F range at + or – 25 deg. F.

 Does my Process Require Pressure Controlled Flue Dampers?  There are benefits to including a pressure transducers and a control motor/linkage in a Car Bottom Furnace. These benefits include greater control over the flue which gives the user excellent temperature uniformity.

 Will my Car be sealed on the side and back walls when inside the Furnace?  Every Car Bottom Furnace should utilize some style of “bumper” system that will thoroughly seal the car inside the unit.  The drive mechanism for the car is shielded by the Refractory surfaces and is located beneath the car.

 Do I need an Accreditation approved Control Panel?  The U.L.is a well known independent, globally accredited Safety Company. U.L. requires a high safety and quality standards for all products. Good manufacturers use components accredited by the U.L.  These parts will have a U.L. Classified Sticker on the unit.

 Will the Combustion System be rated to Factory Mutual, IRI and NFPA 86 standards?  Car Bottom Furnace units should come equipped with several safety mechanisms including surplus Gas Safety shut off valves, High/Low Gas Pressure Switches, Isolation gas cocks, flame supervision with Ultra Violet (U.V.) and Scanners Air Proving switches.  A Car Bottom Furnace Burner should not ignite until a purge air cycle has been concluded at start up. Burners can light on low fire and vary safely to high fire via linkage and drive component.

 Will I need Installation/Start up assistance for My New Car Bottom Furnace?   It is always a good idea to be trained from the manufacturer on your specific unit as well as on trouble shooting tactics whether you have an onsite engineer or not. The manufacturer should also provide you with drawing of your unit as well as an operating manual.

Forming Oven 101

One of the most widely used thermal processes in manufacturing is called Forming. Forming processes are used in nearly every aspect of industrial manufacturing due to its versatility and ability to adapt to every application. Components created in a Forming Oven are used to make everything from Mac truck panels, bicycle helmets and spaceships.

Forming is the process where metal or plastic is stretched, drawn or bent in order to create a desired shape while maintaining the material’s tensile strength and ductility. The prerequisite to forming is that the materials have an ultra fine grain size. Processing materials while in a super heated state called Thermoforming. The desired application and material determine the type of process and temperature performed in the forming oven.  Forming techniques include stretching a material over a mold, vacuuming the material into a concave or blowing air into material to produce a hollowed out center.

One of the major advantages to processing in a forming oven is that you can form large and complex pieces in a single operation. These finished pieces have a fine surface and are created with excellent precision. A forming oven also allows the manufacturer to create very large works which eliminates the need for assemblies and additional pieces. This simplicity means that the finished pieces are lighter, which is particularly important to the aerospace industry. The main disadvantage is the slow forming rate of thick gauge materials, which can equate to a lower volume production for certain products.  Thin gauge materials, on the other hand, can be produced and finished very quickly.

Because a forming oven can be configured to process glass, metal or plastic, these units have become an essential part of manufacturing within the automotive, aerospace and medical equipment industries. Forming ovens are also very popular because their processes incur lower tooling costs than other metal manufacturing methods.

In the last decade forming oven processing, specifically thermoforming processing, has been greatly improved with the advancement of microprocessors and computer controls, which have increased process control and repeatability. Electric servo motors are also now being used in more sophisticated units for actuation of the machine platens, which gives operators more precise control over closing and opening speeds as well as tooling timing.

Railway Concepts Inspiring the Car Bottom Furnace Industry

The biggest news to affect the Car Bottom Furnace Industry is the surge in high speed train proposals across the globe. The two largest proposals have been created by the Chinese who are looking to open world economy and open international relations by connecting the world via train.

In the last 15 years, China has begun an astonishing rail construction spree, laying tens of thousands of miles of tracks and launching high-speed railway lines. China has recently signaled its intent to build a “New Silk Road” heavy-duty freight network through Central Asia to Europe via rail rather than the old caravans that once bridged West and East.

All of this news has been very exciting for the car bottom furnace industry. There is still no word on when industrial furnace companies will get to bid for the car bottom furnace production jobs.

One of the biggest railway ventures in the concept phase is the China-American railway. A project of this size would require numerous car bottom furnaces working around the clock to produce railway and tunnel pieces.

China wants to build a 200km-long undersea tunnel to America via a railway route through Russia, running under the Bering Strait. The 8,000 mile route would need two undersea tunnels connecting Russia and Alaska.

Much like the Channel Tunnel, this new plan to link the East and West has been in concept for a hundred years. Both Russia and China have had great interest in a land route to the U.S. for at least the last 100 years. The proposed Chinese railway plan provides the solution for both countries.

Engineer Wang Meng-shu has laid out a plan for an exact route from northeast China through the Bering Strait. . While this is plan is breathtakingly ambitious, China claims to have the technology. The 8,000 mile route would reduce the need to fly, although at 350kph (220mph) it would still take two days.

China has a number of ambitious train projects in the pipeline. Each of these projects translate into great growth and would fuel new innovations for the car bottom furnace, such as portability and automated systems.

The AISI Annual Report Shows Growth in the Heat Treat Furnace Industry

The American Iron and Steel Institute (AISI) recently released their 2014 Annual Statistical Report (ASR). The report discusses good news and continued growth in the iron and steel industries as well as the heat treat furnace industry.

The American Iron and Steel Institute report details how the industry has seen an increase in U.S. steel production, shipments and imports in 2013. That steady growth has also continued into 2014. These increases in production and imports have also led to increased sales of heat treat furnace units as many manufacturing companies continue to bring processing back in house. Increases in Chinese wages as well as fuel charges have steadily brought more industrial manufacturing and metal working jobs back to the U.S.

The industrial furnace industry has enjoyed continued growth in the sales of heat treat furnace units with both total and finished steel imports quantities levels reaching to near record levels. These imports amass to a record 28% share of apparent steel supply.

Report details also show a steady industry growth over the last few years that is showing no signs of slowing. U.S. steel shipments were counted at 98 million net tons which is a 3% increase from the previous year and a 6% increase from the most recent five-year average solidifying the market growth. This industry growth has helped to fuel the growing number of U.S. manufactures who require a heat treat furnace for production. U. S. raw steel production was 97 million net tons in 2014, a 1% increase over 2013.

In other manufacturing news, President Obama recently signed two significant trade initiatives: Trade Promotion Authority (TPA) and the extension of the Africa Growth and Opportunity Act which includes renewal of Trade Adjustment Assistance (TAA) and trade remedy improvements. The steel and heat treat furnace industries have applauded the action, particularly enactment of the trade remedy measures for which the industry strongly advocated.

A Brief History of the Heat Treat Oven

Necessity is the greatest catalyst for innovation. This was also the case with the invention of the heat treat oven. The more man’s ambitions developed, the more he needed specific tools to accomplish his goals. This is where the idea of the heat treat oven was born.

This journey began with the production of iron somewhere around the 2000 BCE in southern Asia. Iron was replacing bronze due to its strength and durability. At this crude stage open fires acted as the heat treat oven. The iron was heated, worked, heated, worked, and so on until it was ready to be cooled.

The concept of heat treating was one of universal birth. All over the world in different civilizations in Europe, Asia and the Middle East, metalworkers began to enclose the fire pits little by little as it was noticed that heat uniformity and heat retention had a substantial effect on the product and on the productivity of the worker.

As man’s dreams for iron implements became more and more specialized, so did the heat treating requirements. The heat treat oven became a tool for science and engineering.  Heat treating became more than just a means of creating a desired product; it became the science of learning to controlling metallic compositions and their properties.

3,000 Years later steel replaced iron and brought with it a myriad of possibilities. Steel was stronger, more flexible, and more durable than cast or wrought iron. That said, producing steel was also time-consuming, labor intensive and costly.

As the demand for steel grew with the railway boom, a new process emerged called the Bessemer Process. This process allowed high quality steel to be manufactured in minutes instead of days and while using less fuel and labor.

From these earliest heat treat ovens of the Iron Age to the creation of mass assembly lines, heat treating has touched all aspects of everyday life from railroads, pipelines, refineries, vehicles, infrastructure, buildings, bolts, nuts, washers and dryers, and tools of every kind.

The heat treat oven revolutionized the world by providing endless possibilities for the creation, development and use of metals.

Meet Tim Bacon, Director of Operations & Industrial Oven Guru

As a part of my research into Industrial Ovens, I had a chance to interview a gentleman who has spent his life in the Industrial Oven business.

Tim Bacon has been officially involved with industrial oven building  for 20 years although he has grown up working in the shop at his father’s business. Tim’s father is Ernie Bacon, the owner of Baker Furnace. Tim has been learning the trade and working in the shop since he was a teenager. Naturally, Tim’s love for the industrial oven business and the creation process led to his current career as the Director of Operations at Baker Furnace, Inc. in Southern California.

The following is my interview with Tim Bacon.

How did you first get your start in the business Tim?

“Just like every teenager, I got my start making industrial ovens because I wanted to earn some money. My parents paid me to work in the shop during summer vacation”.

What do you love about the industry and your job?

“I really love the versatility! I love the different industry challenges. Each industrial oven is its own puzzle to solve and to design for the customer.  Each company has its own specifications and applications that they need to have accommodated. Rarely are any two heat treating ovens, afterburners, or thermal oxidizers the same. The randomness of the variables makes each project exciting and different”.

What, if any, are your dislikes?

“Well, it’s not really a dislike, but the growing amount of different heating application in the industry makes things a lot more complicated. It used to be that Baker Furnace only manufactured a few types of industrial ovens. Now, we custom manufacture everything from conveyer ovens to composite curing ovens and even liquid waste incinerators. It is a lot more challenging to reinvent the wheel every time”.

What has been the biggest change that you have seen in the industry over the past two decades?

“Actually not much has changed. Lots of the concepts and construction methods are the same because there are only a few different ways to make an industrial oven. The parts and controllers have become more sophisticated and software based, but the classic oven design is still the best”.

Thermal Oxidizers, Bringing You Clear Blue Skies

The average person has never heard of thermal oxidizers. But whether you have heard of them or not, these machines are essential to the way we live and to our safety.

A thermal oxidizer is a combustion device used to control air pollution by destroying VOCs (volatile organic compounds). The hazardous gasses are heated at extreme temperatures until the pollutants breakdown into a harmless gas. Thermal Oxidizers are also known as industrial afterburners.

The main reason for thermal oxidizers is to eliminate harmful VOC’s. Volatile Organic Compounds are the byproduct of the heating process where these harmful chemicals are released into the air. The majority of these harmful compounds are hydro-carbon based. Some VOC’s occur in nature and some are manmade. Scents and odors are VOC’s, like those of flowers, for example, which are harmless. The problem is that the majority manmade VOC’s are extremely harmful, both to the environment and to the lungs if inhaled. The effects of inhaling VOC’s compound and cause damage in your body and in the atmosphere over time.

The paint and protective coating industries are some of the largest producers of VOC’s. Over 12 billion liters of paint are manufactured every year. Benzene, created from tobacco smoke as well as auto exhaust is a large VOC creator. Methylene chloride is one of the most harmful VOC’s found in aerosol sprays which are known to cause cancer. Other VOC creating industries include chlorofluorocarbons which are used to make cleaning materials.

Thermal oxidizers work by connecting to the manufacturing machines at the processing plants. As the VOC’s are created during the heating process, the gases are funneled through ducts into the thermal oxidizer. The oxidizer then heats the gases to extremely high temperatures until the dangerous contaminants are reduced to CO2and H2O.and nontoxic air is left. The harmless gases are then released into the air.

Each country and state have their own codes and regulations for the amount of VOC’s that are allowed to be dispersed into the air, water, and land. For the specific regulations in your area, visit the United States Environmental Protection Agency’s website for more information.

Six Questions to Ask When Purchasing A Heat Treat Furnace

Let’s face it, you don’t buy a heat treating furnace every day. Purchasing a heat treating furnace can be a large undertaking with several variables and costs to consider.  We’ve taken our 35 years of experience building heat treat furnaces and compiled the top 6 questions that you need to ask to ensure you are purchasing the best quality furnace for the best value.

We hope this information will empower you to make a sound decision.

1. What temperatures can I achieve inside the Furnace?  Generally, a Heat Treat Furnace operates from 800 degrees F up to 2200 degrees F.  High quality manufacturers should insulate the furnace with a combination of Ceramic Fiber and, Castable Refractory and Heavy Duty Refractory brick.  Linings as thick as 12” thick are used on 2200 degree F unit.

2. What is a typical Temperature Uniformity Specification for a Direct Fired Heat Treat Furnace?  A Heat Treat Furnace typically operates at plus or minus 25 degrees F uniformity inside the furnace’s “working space”. Tighter uniformity (plus or minus 10 degrees F) has been achieved on some direct-fired units. You should also ask about proprietary designs from the manufacturer to ensure optimal uniformity and efficiency.

3. How can I be assured air won’t leak and the doors will seal properly over time?
Typically, oven doors will sag over time if not engineered properly. It is essential you ask the manufacturer if they have a proprietary door design that has been tested and proven. Better yet, find a manufacturer that will guarantee their doors for the life of the oven.  If they won’t guarantee the doors, you should be skeptical.

4. Is the Control Panel approved by an accredited Agency?  Any good manufacturer will be accredited by the U.L. The U.L. is an independent, global accredited safety science company aimed at maintaining s high standard of safety in the workplace and quality of the product being manufactured. Control Panels have a U.L. Classified Sticker affixed inside. All components in the U.L. Classified Control Panel are U.L. listed or recognized.

5. Is the Combustion System rated to meet Safety Standards: Factory Mutual, IRI and NFPA 86?  A Heat Treat Furnace should include numerous safety components including redundant Gas safety shut off valves, Isolation gas cocks, High/Low Gas Pressure Switches, Air Proving switches and flame supervision with Ultra Violet (U.V.) Scanners.  Burners should not light until a purge air cycle has been completed at start up. The burners light on low fire and modulate safely to high fire via linkage and drive component.

6. Will I receive Installation/Start up/Training assistance?  A standard Heat Treating Furnace should be supplied with detailed general arrangement drawings as well as installation drawings.  Make sure the manufacturer has engineers on staff that will assist on site with the installation, training and start up of your furnace.

Depending on your requirements, there are several other questions that may come up, but we hope this helps you in your initial stages.  If you need more information, you are always encouraged to call one of our Heat treat Furnace specialists, that are happy to answer your questions with no obligation.
