Roller Hearth (High Speed Output Application)
Therser Wellman supply both gas-fired and electrically heated Roller Furnaces, suitable for a wide range of industrial applications and over a wide range of load shapes and sizes.
This furnace concept offers a continuous product processing line, with entry and exit doors at either end of the furnace. A continuous bed of high temperature rollers, driven by individual motors or ganged chain drives, moves the product along the furnace and through the required heating profile specific to the product requirements. Given the lighter duty, high speed nature of the products being processed the rollers are typically manufactured in a suitable load bearing ceramic material. However metallic rollers are also available in this type of furnace design.
The High-Speed design concept is suitable for high output component parts, typically 1 part every 10 seconds, and has been used in hot press forming applications or similar high speed lines. Depending on the furnace heating profile and speed of travel continuous furnaces of 50 metres long have previously been supplied.
In addition to the furnace, downstream processes such as air-blast cooling and water quench can also be provided.
These can be applied with protective/reactive atmospheres to prevent oxidization (In process) or enhance metallurgical properties within parts.
All of our robust and energy efficient furnace designs would be built around your process requirements/needs to give a solution tailored to getting the best out of your process.
