Questions & Answers
FAQ – Aichelin Ring Hearth Furnace Systems
The system eliminates reheating, reduces energy consumption, and delivers more precise hardening results.
Aichelin ring hearth furnace systems use gas and/or electric heating systems. The atmosphere control is precisely matched to the process using endogas or nitrogen/methanol with additional gases. All protective atmosphere systems are equipped with a nitrogen safety system.
In the Aichelin ring hearth furnace system, the three-ram hardening press is fully integrated into the control and automation system, enabling reproducible press hardening results.
The system is primarily used to treat gears and other transmission components made of typical case-hardening steels.
The system offers reduced operating costs, lower maintenance effort, a compact layout, and an energy-efficient, process-stable overall system.
