Top 10 Roller‑bottom Tempering Furnace Manufacturers Worldwide

Roller‑bottom tempering furnace (roller‑hearth tempering furnace) is continuous‑type heat‑treatment equipment for high‑temperature and low‑temperature tempering of steel workpieces. Featuring uniform temperature field, stable roller transmission, low workpiece deformation and high continuous production efficiency, it is widely used in automotive parts, hardware tools, bearing components, steel pipes, fasteners and machinery manufacturing industries. It can operate independently or integrate with quenching lines to realize full‑process heat‑treatment production. Below is an overview of top global manufacturers of roller‑bottom tempering furnaces.
