| Abstract: | In order to improve the temperature system of the infrared oven in 24 heads rolling mill,software and hardware have been combined in the designing scheme of the temperature controlling system.The main hardware is composed of thermal resistor as temperature sensor,87C51 single chip processor,as main control computer,together with amplifier and A/D transfer.Integrator-discrete PID algorithm is adopted in software to prevent the temperature from over-high or over-low and make it invariable.After innovation,the fluctuation of temperature for the new system is less than ±0.5℃/30min and the mean error is less than ±1℃.It can fix the pipelining very well. |
