Angle rolling process parameter determination method, device and equipment and readable storage medium

Abstract

The embodiment of the invention provides an angle rolling process parameter determination method, device and equipment and a readable storage medium, and the method comprises the following steps: starting from an initial rolling pass, circulating the following steps to determine the rolling pass of angle rolling: calculating the maximum steel rotating angle under the current rolling pass; according to the maximum steel rotating angle, the width of the plate blank after rolling of the current rolling pass is calculated, and a first corner of the plate blank after rolling of the current rolling pass is calculated; when the number of the current rolling passes is an odd number, whether the rolling passes are increased or not is determined according to the relation between the width of the rolled plate blank and the target width; when the current rolling pass is an even number, whether the rolling pass is increased or not is determined according to the relation between the first corner and 90 degrees, when the first corner is equal to 90 degrees and the width of the rolled plate blank is smaller than the target width, the rolling pass is increased, and when the first corner is equal to 90 degrees and the width of the rolled plate blank is larger than or equal to the target width, circulation is ended; and determining that the current rolling pass is an angular rolling pass.

Description

technical field [0001] The invention relates to the technical field of rolling, in particular to a method, device, equipment and readable storage medium for determining parameters of an angle rolling process. Background technique [0002] With the rapid development of my country's economy and military, the demand for large-scale medium and thick plates is increasing day by day. The thickness control of medium and heavy plates is mainly through increasing the thickness of the billet or adopting technologies such as water-cooled steel ingots; while the width control technologies of medium and heavy plates mainly include: horizontal rolling (widening) + longitudinal rolling technology and angle rolling-longitudinal rolling technology. [0003] Among them, horizontal rolling + longitudinal rolling technology is currently the main widening process for medium and heavy plates. Such as figure 1 As shown, after the slab is dephosphorized, it is rotated by 90 degrees, rolled and st...
