Quality Control Strategy for Hot-rolled High-strength Steel Plate Shape
In order to explore the methods for controlling the shape quality of hot-rolled high-strength steel plates,eliminate adverse factors,and optimize production levels,taking the X70 steel pipe line production as an example,based on the existing edge wave problem in the production of hot-rolled high-strength steel plates,a three-dimensional finite element model was established using ANSYS parameter language to analyze the factors affecting the shape quality of hot-rolled high-strength steel plates.Targeted methods were proposed to control the thickness and width of hot-rolled steel plates,compensate for rolling force fluctuations,control rolling temperature,and control roll shape,in order to control the shape of hot-rolled high-strength steel plates.Through example verification,the load distribution power has been reduced by 3.37％,the flatness has been increased by 56％,and the convex hit rate has been increased by 11％,achieving good results.
