| Abstract | Koyo Thermo Systems Co., Ltd. and JTEKT Corporation have jointly developed an energy-saving highperformance continuous carburizing furnace with the aim of achieving energy conservation and high functionality. To reduce energy consumption, measures were taken to reduce the amount of heat energy dispersed from various furnace areas (frame surface, inner passageways). To improve functionality, variations in in-furnace temperature and gas uniformity were reduced. This was accomplished by optimizing the inner structure utilizing a 3D fluid simulator to improve flow speed within the furnace and by adopting a new temperature control method (multicontrol). By these measures, the developed furnace exhibits advantages over conventional furnaces in energy costs, surface carbon concentration consistency, and heat treatment cycle time. |
