[0013] Such as Figure 4 As shown, in the traditional control mode, the first tension roller group 2 measures the actual value of the entrance tension of the heat treatment furnace through the first tension meter 3, and the first tension roller group 2 is adjusted in real time through the first tension closed loop control unit 4 to realize the heat treatment The inlet tension of furnace 5 is stable. The second tension roller group 6 is speed controlled to keep the speed of the process section stable. The fourth tension roller group 10 measures the actual value of the outlet tension of the pickling section 8 through the fourth tension meter 9. The fourth tension roller group 10 is adjusted in real time through the fourth tension closed-loop control unit to realize the stability of the pickling section outlet tension.
[0014] In recent years, the production of metallurgical strips in the world, especially stainless steel strips, has developed rapidly. In order to increase product...
