Introduction to packaging steel strip production mill operation control method

Packaging steel strip production mill operation control method introduction to Zagreb machine safe and high efficiency, high speed operation, has one batch of sequence control for automatic operation, the operation of the mill this includes automatic acceleration, deceleration, automatic parking and includes pickling - Mill unit in control of the pickling line, coordination control and the entire production line speed. If the main control function of a cold rolling automatic position/pressure control, the thickness of the main speed cascade, automatic control, automatic flatness control functions always called operation control, other than the operation control includes the following two functions: ( 1) Associated with rolling mill automatic control speed control. ( 2) The speed control of associated with manual operation. Belong to the first category has a population of loop speed control, loop control car, looping export period of speed control, weld automatic deceleration and BianTong cold rolling with the automatic speed, automatic deceleration control and automatic parking. Belong to the second class is carried out by operators rise speed, constant speed, lower speed, wear, spin, abrupt stop, calibration of weld and the operations, the switching mode as shown in figure 2 - of all kinds of operating status 4. Table 2 - 5 lists the different speed choice jostle for condition. Below is an object with the continuous cold rolling narration looping population, period of speed control for export. In order to keep the cold tandem rolling unit steady speed rolling at high speed, the continuous cold rolling in tandem mill set population capacity of the loop, and set up welding machine and other equipment in looping population to strip continuous constant supply raw materials. In order to reduce the length of loop area, the whole loop is divided into 3 layers, each layer with looping car to traction strip ( Looping the car by the traction steel wire tie) , when the live set of district 120 m, can store 720 m strip steel.
