Our roller hearth furnaces, model DORES, are suitable for the heat treatment of flat, thin-walled components, beginning at a diameter of 42mm. These parts, which are used for e.g. rolling bearings, automotive clutches and motors, or as disc springs, run without grates or any further foundational structures on small, individually powered rollers through the furnace chamber with inert gas. The discharge of parts from the furnace into the connected quenching device is cycled in high speed.
Here, it is possible to combine this process with a hardening press or a gas quenching station. We use Rollmod® as the high-temperature transport system. Depending on your required throughput, type of heat treatment and part geometry, we will design the furnace or recommend the optimal furnace design.
