Steel-sticking edging control method for edging mill

Abstract

The invention discloses a steel-sticking edging control method for an edging mill. The steel-sticking edging control method comprises the following steps: step 1, executing roughing and tailing-out processes on edging rolls; step 2, enabling the edging rolls to enter a tail clamping mode, and performing tail clamping site propping; step 3, judging whether the edging rolls are in contact with a steel plate or not; step 4, saving a roll gap value as the width of a plate blank; step 5, judging the size relationship between the width of the plate blank and a set roll gap; and step 6, adjusting a working site set value. The steel-sticking edging control method for the edging mill avoids steel sticking caused by excessively large rolling reduction when the steel plate enters the edging mill to be subjected to normal rolling, can guarantee that the edging mill realizes successful steel biting, and achieves the purposes of protecting the edging mill, accurately controlling the rolling reduction and improving the yield.

Description

technical field [0001] The invention relates to an automatic control method of an vertical roller mill, more specifically, to a method for controlling edge rolling of steel jammed by the vertical roller mill. Background technique [0002] Such as Figure 1 ~ Figure 3 As shown, the traditional vertical roll rolling method is as follows: receiving the steel plate information and setting values ​​of the host computer, setting the roll gap and the main drive speed of the vertical roll according to the setting values ​​of the host computer, and the roll gap of the steel plate before entering the vertical roll mill Set it in place and implement the biting speed, implement the rolling speed after the steel plate head exits the vertical roller mill, execute the steel throwing speed when the steel plate exits the vertical roller, and the vertical roller rolling pass is completed. [0003] However, in actual use, the following special situations will occur: [0004] In the traditiona...
