Embodiment Construction
[0019] The present invention will be further described through the embodiments below in conjunction with the accompanying drawings.
[0020] Refer to attached figure 1 , in an embodiment, after the rolled steel strip 2 on the uncoiler 1 passes through 1# frame 3, 2# frame 4, 3# frame 5, and 4# frame 6, it is coiled by the coiler 7 .
[0021] Refer to attached figure 2 , the present invention is divided into three grades according to the thickness of the steel strip at the exit of the rolling mill, the first grade is the thickness h0.80mm; it is determined according to the thickness grade δ 1 ,δ 2 、D 1 、D 2 Tension compensation parameters, establish a database of tension compensation parameters.
[0022] The automatic realization of the present invention is that the corresponding PLC writing control program of rolling mill coiler reaches T 1 , T 2 , T 3 Calculation, output and control. Set tension T S The initial value of is imported from the model calculation valu...
