Embodiment Construction
[0055] In order to better understand the above technical solutions of the present invention, a further detailed description will be given below in conjunction with the drawings and embodiments.
[0056] figure 1 It is a control flow diagram of an embodiment of the method for controlling the variable speed at the entrance of the hot rolling mill finish rolling of the present invention. The control method of the present invention is used in the flying shear shear speed control software of the continuous rolling mill during the hot rolling process. The described Flying shears are placed before the F1 stand at the entrance of the finishing rolling of the hot tandem rolling mill. The incoming strip passes through the deceleration point and enters the deceleration section, decelerates to the shearing speed of the flying shears, and is sent to the F1 stand after being cut by the flying shears. In the field of hot rolling, the definitions of steel grades by different manufacturers in...
