The whole set of equipment consists of three parts: furnace body, mesh belt drive system and temperature control system. The furnace body consists of a feeding section, a pre-sintering section, a sintering section, a slow cooling section, a water cooling section and a discharging section. The mesh belt transmission system is composed of high temperature resistant mesh belt and transmission device. The running speed of the mesh belt is adjusted by the frequency converter, equipped with a digital display mesh belt speed measuring device; the mesh belt speed can be directly read; the temperature control system is composed of thermocouples, digital display intelligent PID regulators and thyristors, forming a closed-loop control system , which can realize automatic and precise temperature control.Heat Treatment of DZ4 Alloy in High Pressure Gas Quenching Vacuum Furnace
