串列式轧机

控制系统的主要特点:

1.多台直流电动机的速度、必要的逻辑控制。

2.主机通过张力传感器实现各机架间的张力闭环控制。

3.卷取的张力给定、自动降速甩尾;卸卷、运卷控制。卷径计算、动补、空补、张力控制、断带保护等功能。

4.通过HMI在线更改机列各种工艺参数,监视系统各部分状态和过程数据,集中显示并可监控并记录各种工艺数据、历史趋势;

5.故障诊断。内部设有专门的诊断程序,并将各种重要信号的状态在HMI中动态地显示出来。大大缩短维护人员判断故障和寻找故障所在点的时间。


The main features of the control system:

1. Multiple speed DC motor, tension control, and necessary logic control. 

2. The unwinding and winding tension is given with automatic deceleration flick. The unloading and transporting of the roll are under control. All products are equipped with diameter calculation, movable fill, static fill, tension control, and belt protection. 

3. Cooperated with the pressure sensors and displacement sensors, the encoders can achieve automatic liter deceleration and braking functions. The unit is also equipped with the functions of calculation of coil diameter, turns, and belt length. 

4. On the HMI operation screen, there is an input function of the rolling process table. During the automatic rolling process, according to the parameters established in the automatic rolling process, the system can set parameters according to each of these variables, thus achieving automatically completion of the production of the strip of each volume. The operator can adjust some of the rolling process parameters, such as front and back tension value. 

5. Troubleshooting. The products have been equipped with specialized diagnostic procedures. The status of various important signal can be dynamically displayed in the HMI screen, which can greatly reducing the time of the maintenance personnel to determine the fault and to find the point of failure.
