Ipsen designed, and delivered, an atmosphere heat-treating three-row pusher system for Mercedes-Benz. It will be used for the thermal processing of gearbox parts, crown wheels and drive pinion wheels. The pusher furnace utilizes three rows in all of its main operating zones and is the first continuous heat-treatment furnace from Ipsen to feature the new, patented Lock-Up system. This system incorporates an entrance vestibule and an oil bath, both of which are separated from the furnace’s heat-treatment chamber by gas-tight doors. Therefore, the furnace atmosphere fluctuates less in terms of temperature and carbon potential, resulting in precise, steady characteristics that are easy to monitor.
