Project Background
Hyco International is a world leader in the supply of hydraulic cylinders for the mobile equipment market. With 6 manufacturing facilities on three continents and a dedicated and highly motivated team of employees, Hyco makes the industry's most complete range of cost competitive hydraulic cylinders. The engineers had a specific preheating application that was required for their hydraulic telescopic and rod cylinders. The casings needed to be preheated to a temperature of 600F within a period of 2 hours before they moved on to the assembly phase. The items to be preheated would rest inside the oven upright to ensure even, quick preheating. The customer wanted the oven to be top-loading and forced-convection.
For this particular application we designed a custom industrial preheating oven from scratch and called it the K-TL-FC6. It had to be top-loading, and because of the size of the unit, we designed unique, split top-loading doors with heavy duty handles to allow for the easy loading and unloading of the parts. A 1HP blower was installed at the back of the oven for forced convection, allowing the parts to be heated quickly in the time frame required. The preheat oven is insulated all around, including the doors to ensure containment of heat and rapid preheating of the cylinder casings. The K-TL-FC6 preheating oven rests on lockable casters to enable free movement of the oven around the workplace and to different workstations.
This custom oven is useful for a variety of purposes, not just for cylinder casings. The temperature range can be modified for any application. A miniature programmable digital controller was installed for this oven so the temperature reading would remain very accurate.

Oven Construction
Exterior
The K-TL-FC6 heat treating oven is constructed of carbon steel throughout. The oven exterior has a highly durable, powder-coat finish in blue that is resistant to scratching and corrosion. This a top-loading, floor-positioned preheating oven and is designed to be stored on a floor for ease of access to the parts being preheated. The 1HP blower is installed at the back of the oven and is protected by a steel cover. Lockable casters underneath the oven allow for easy transport to various workstation areas. The door hinges are tack-welded to ensure smooth operation for many years. The control panel which houses the digital PID is mounted on the side of the oven with heavy-duty rivets. A standard "ON/OFF" indicating light was also provided, which is bright enough to be seen from a distance. A variety of temperature control methods are available at preheatovens.com.
Interior
The interior of the K-TL-FC6 preheat oven is fairly simple. No shelves were needed, but various shelving styles are available at preheatovens.com suitable for almost any custom preheating application. The elements are installed in the the sides of the oven which allows the heat to radiate inwards and around the oven. The interior of the K-TL-FC6 preheating oven is painted with a reflective, galvanized paint and the interior welds are touched up with high-temperature aluminum paint.
All our preheating ovens are made in the USA and feature a 1-year limited manufacturer's warranty. Parts are readily available.
Design And Build Your Own Custom Industrial And Welding Ovens
Each customer often has a specific process that requires the heat treating of parts, components or materials prior to assembly. Their parts are unique in size and shape, and a customized heat treatment oven specific to the part and application is often the only solution to streamline the process. Keen is your solution.
Frequently Asked Questions
What is a preheat oven?
We use the term preheat oven to describe an oven that is used for preheating parts before they are used in some type of application. Most of our preheat ovens are custom-designed according to the specific application being performed by a client. Many processes require the preheating of weldments before they are bonded to some other type of metal. This preheating is required to change the property of the metal part and enable it to be installed onto another part. Our ovens are used in many applications. The K-450TL hatchable oven used on ships is just one example. We have designed ovens for bowl shafts, cylinder heads, cylinder blocks, military tank transmissions and for many other types of parts.
Why is preheating steel before welding a necessary procedure?
It depends on the application requirements. Many steel components for a variety of industries require preheating to prevent problems in the weld after the job is complete. Keen's custom preheat ovens are an excellent preheating solution to many welding applications. Rather than heat each part at a time, we often have customers that load an oven with many parts at once and leave the oven on all the time. This way they have parts ready whenever they need them, at the right temperature. Each welding application has its own thermal treatment requirements, so be sure to check what is need for your next procedure.
Can this oven be modified for other applications?
Yes, absolutely. Many of our custom ovens have resulted from client requests to modify an existing oven they have seen on our website, or to one of our standard welding electrode ovens that a client may be using for welding applications. The process usually begins like this: a client finds one of our ovens that has an interior size close to what can accommodate the parts that need to be preheated, and then inquires if modifications can be done. Our engineers get to work to provide suggestions to the client as to what modifications can be done. If the modifications are not suitable, we design a new oven from scratch to fit the users needs.
Do you provide CAD drawings for review?
Yes. Keen's custom oven design process typically begins with a discussion of the various solutions we are able to provide to the client. If the client wants to proceed, we then do a CAD drawing for review that clearly outlines the custom oven design for the client to review.
Do you manufacture gas-fired ovens?
No. We only manufacture electrical ovens with a maximum temperature range of 1000°F
Are your products made in USA?
Yes. We manufacture our ovens in Louisiana.
How long have you been in business?
