Furnace rollers made from Kanthal APMT, an iron-chromium-aluminium (FeCrAl) alloy, for heat treatment furnaces with operating temperatures up to 1250°C (2280°F). Kanthal furnace rollers are available in outside diameters from 26 to 350 mm (1 to 13.8 inch), according to customer design.
The Kanthal program includes, for example:
- Furnace rollers for continuous furnaces
- Furnace rollers for roller hearth furnaces
- Furnace rollers for walking beam furnaces
Longer service life compared to conventional materials
Furnace rollers made from Kanthal APMT provide considerably longer service life and reduced maintenance compared to furnace rollers made from conventional materials such as nickel-chromium (NiCr) alloys and ceramic materials. This is due to the material's excellent creep rupture strength at high temperatures. Furnace rollers made from Kanthal APMT are also characterized by a very smooth surface which ensures a consistently high-quality finish of the manufactured products
