摘　　要：介绍了陶瓷磨具工艺试验炉温度控制系统的设计方法。该试验炉由炉体、热电偶、发热元件和温度控制系统组成。发热元件选用硅钼棒，使得硅钼炉温度可从室温-1400℃任意控制，试验炉的功率3 kW。采用钨铼热电偶作为测量高温的器件，系统测量误差≤0.1℃。使用8031单片机作为温度控制系统的核心；控制算法采用经验规则＋PID控制方法，使控制稳态误差≤1℃，较好的解决了试验炉时变惯性特性。A temperature control system of technology testing furnace for vitrified abrasive tools was designed in this paper. It is consist of body of furnace, thermocouple, component of heater and temperature control system. Silicon - molybdenum was chosen as heater component and temperature of furnace can be controlled from indoor temperature to 1400 ℃. The rated power of furnace is 3 kW. Wolfram - rhenium thermocouple which is of small transport lag was used to measure the high temperature of the furnace. Single chip microprocessor 8031 plays role of core of temperature control system. Combination of experiment rules based control strategy and PID was employed to solve time - variant, transport lag drawback of the furnace. The steady state error of the system is less than 1℃.
