Abstract: In order to fulfill the application requirements of foundry industry, especially for the bulky casting sand, a kind of desiccations resolution using the air heater was put forward. The realization of kernel parts, including the temperature collection circuit and the control arithmetic, was described in detail. By the simulation in the open environment, it is proved that the design has the perfect speed of response and the high superposition of heat curve, and also, it can be fit for the design requirements of the air heater temperature control in foundry industry.
Key words: foundry; air heater; temperature collection; PID control
