The whole equipment consists of three parts, the furnace body, the network belt transmission system and the temperature control system. The furnace body consists of a feeding section, a burning section, a sintering section, a slow cooling section, a water cooling section and a discharging section. The network belt transmission system is composed of high temperature resistant mesh belt and transmission device. The operation speed of the network belt is adjusted by the frequency converter, and the digital network belt speed measuring device is configured, and the direct reading network belt velocity is adopted, and the temperature control system is composed of a thermocouple. Digital explicit intelligent PID regulator and SCR, which form a closed-loop controlling system to realize automatic precise temperature control.
