Don Marteeny, Technical Director at Seco Vacuum Technologies, Meadville, Pa., will present a discussion of multi-chamber vacuum systems developed for high-throughput, highly precise low-pressure carburizing applications at Heat Treat 2019.
Compared with traditional gas carburizing in continuous or batch integral quench atmosphere style furnaces, low-pressure carburizing (LPC) run in modern vacuum furnaces reduces carburizing gas consumption while providing more consistent results when considering case depth, surface hardness, and core hardness. Multi-chamber furnaces provide this level of precision, while also maintaining the high production level required in automotive or aerospace applications.
To understand the potential benefits of these systems, two sample applications will be presented using a triple chamber semi-continuous vacuum carburizing system. Both oil and gas quenching capabilities are considered. The results show the semi-continuous, triple chamber design is capable of similar results, if not superior, while providing increased productivity and uptime versus more traditional multi–furnace or continuous furnace systems.
