1.采用PLC内置温度控制功能控制热辊温度

热辊的加热是由主加热和副加热组成，二者的控制是独立的，但热辊是一体的，由于温度传导的作用，主加热和副加热互相影响，因此对温度控制器的性能要求很高，传统的热辊温度控制方案都是采用比较的温控表控制，价格较高。

合信技术根据热辊的温度控制特点要求，设计了的模糊温度控制算法，采用这种算法合信的PLC即可胜任，其控制效果到达了热辊的要求，精度为?1?C，超调量≤3%。由于省却了温度控制仪表，显著降低了系统 成本，改善整体电气系统结构，减少故障率。

1. Use PLC built-in temperature control function to control the temperature of the hot roll

The heating of the hot roll is composed of the main heating and the secondary heating, the control of the two is independent, but the hot roll is one, due to the effect of temperature conduction, the main heating and the secondary heating affect each other, so the performance of the temperature controller is very high, the traditional hot roll temperature control scheme is the use of comparative temperature control meter control, the price is high.

According to the requirements of the temperature control characteristics of the hot roll, the fuzzy temperature control algorithm is designed, and the PLC can be competent by using this algorithm. The control effect reaches the requirements of the hot roll, and the accuracy is. 1? C, overshoot ≤3%. Because the temperature control instrument is avoided, the system cost is significantly reduced, the overall electrical system structure is improved, and the failure rate is reduced.
