Preventative Maintenance for your Conveyor Oven

In the world heat treating, a conveyor oven is a very unique piece of equipment that must be maintained to mitigate large break downs. Processes like tempering, preheating, quenching and annealing all require an efficiently functioning unit to maintain production deadlines. While some downtime is expected when working with large pieces of machinery, less time lost is better. This is why preventative maintenance is so paramount. Compared to the price of purchasing a new conveyor oven, the cost of regular repairs is much more reasonable. A little fiscal planning can go a long way when it comes to taking care of your equipment and your business.

Before scheduling maintenance on your conveyor oven, make sure that the technician is a qualified maintenance mechanic that has experience working with heat treating equipment.

The benefits of regular maintenance on your conveyor oven are numerous. For starters, you are able to schedule repairs at a time when production will be least affected. Regular care will also extend the life of a conveyor furnace. A well maintained unit will also protect your business by ensuring quality production and deadlines met on time.

Here are some helpful guidelines for the preventative maintenance of your heat treating or conveyor oven unit.

Preventative maintenance on your conveyor furnace begins with a regularly scheduled and thorough inspection of the entire unit. These inspections are able to catch small issues before they become large and costly problems. Any amount of energy loss is problematic for these conveyor furnace or other heat treating units whose processes are performed continuously.

The best rule of maintenance is keeping your equipment clean. The front and rear louvers and ventilation ports require regular cleaning. Before touching the temperature controller or control panel make sure that your hands are clean from oil, chemicals and dirt. Always clean any spills or other deposits from the chamber walls. Be careful when loading and unloading the chamber so that the thermocouples and heating elements are not damaged.

Another important task is to lubricate the moving parts of your conveyor oven. The fan shaft bearings need to be lubricated with high-temperature lithium grease every 3 months. The fan belt also needs to be regularly inspected for cracks and worn areas. Be sure to never exceed the maximum temperature of your furnace.

Be mindful of the amount of energy being used during production. A change in the amount of energy being used could mean your conveyor furnace is not running at optimal efficiency. Lastly, be sure to regularly inspect the door seal for any heat or energy loss.

These easy maintenance tips can help prevent costly repairs and maintain production schedules. Be sure to refer to your Operating and Maintenance Manual from the manufacturer when performing any repairs or maintenance on your conveyor furnace.

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.

What is an Enclosed Ground Flare?

An Enclosed Ground Flare, also known as a thermal oxidizer or vapor combustor, is a combustion system that takes exhaust gases which are potentially toxic or flammable and converts them into less harmful vapors without using a stack.

There are two main types of ground flares, enclosed ground flares and open ground flares. The advantage of having an enclosed ground flare is that it does not require supports or a stack, like an elevated flare would. The removal of the stack portion of the system allows pilots and other weather sensitive equipment, which has a tendency to corrode, to be easily replaced and cleaned.

An enclosed ground flare is much more common than an open ground flare. This combustion system utilizes a refractory shell to enclose the incineration process. This essential shell shields radiation, the internal blaze and noise. The internal processes of the enclosed ground flare are the same as that of the elevated flare.

While an enclosed ground flare has a higher price tag, they are less expensive to operate and are easier to maintain. The handling capacity of an enclosed flare is between 50,000 and 250,000 lb/h and most units are smokeless.
An open ground flare can come in several different configurations. Most systems have multiple burners working together ignite large amounts of gas. Open ground flares are able to burn larger quantities at a time. These units are almost completely smokeless and have a very high gaseous conversion rate.
The open ground flare units contain a limited amount of space for the burners. This means that the units must be kept at a distance for safety reasons. These systems also require a gas pressure of 3-5 psi, which is much higher than any other type of flare system. While open ground flare units are effective, their bright light, noise and heat emissions require that the unit be used in a more secluded area.

Enclosed Ground Flares emit less noise, light and heat.

System Comparisons

Type Enclosed Open Elevated
Height Ground Level Ground Level Elevated
Price Higher Median Median
Operating Costs Lower Lower Highest
Disturbance Rating Lower High Low
Capacity Limited High High
Special Operating Issues No Yes Yes
Safety Rating Higher Lower High
Ease of Maintenance Easy Easy Harder
