Setting method, device and system for trimming width of cold rolled strip steel

Abstract

The invention relates to the technical field of cold rolling, in particular to a setting method, device and system for a trimming width of cold rolled strip steel. The method comprises the steps of acquiring calculation data in a strip steel production data packet; calculating a strip steel elongation coefficient according to a strip steel elongation coefficient calculation model; calculating a strip steel trimming width set value; and sending the strip steel trimming width set value to a cold rolling control device for setting. The device comprises a data acquisition unit, a first calculation unit, a second calculation unit, a sending unit and a modification unit. The system comprises a cold rolled strip steel trimming width setting device, an upper computer and the cold rolling control device. According to the setting method, the device and the system for the trimming width of cold rolled strip steel provided by the invention, the trimming width of cold rolled strip steel is automatically calculated and set, the accuracy of the cold rolled strip steel trimming width set value is improved, and a lot of manpower and material resources are saved.

Description

technical field [0001] The invention relates to the technical field of cold rolling, in particular to a method, device and system for setting trimming width of cold-rolled strip steel. Background technique [0002] Cold-rolled steel strips generally have a thickness of 0.1-3mm and a width of 100-2000mm. They are all made of hot-rolled steel strips or steel plates, and are rolled into products by cold rolling mills at room temperature. Cold-rolled steel strip has the advantages of smooth surface, high dimensional accuracy and good mechanical properties. Most of the products are coiled, and a large part of them are processed into coated steel plates before leaving the factory. Coiled cold-rolled strip steel has high production efficiency, is convenient to use, and is beneficial to subsequent processing, so it is widely used and has gradually replaced hot-stacked rolled sheets of the same thickness. The output of cold-rolled strip has accounted for about 30% of the total steel...
