The invention provides a roll gap control method based on the mechanical parameters of the rolling contact interface segmentation model. The specific implementation steps are: S1. The characteristics are divided into microelements in different deformation zones; S2. According to the microelements in the rolling deformation zone, the volume expression of the metal flow in the rolling contact interface is established; S3. According to the contact arc length l and The ratio of the average thickness of the rolled piece, divide the rolling contact interface into sections and calculate the unit rolling pressure in each section; S4, calculate the corresponding total rolling force P according to the unit rolling force calculated in S3 i ; S5, the total rolling force P calculated by S4 i The value is compared with the set allowable deviation range e value for dynamic adjustment. The invention can accurately calculate the rolling force in rolling, and timely find out the deviation between the actual rolling force and the set rolling force in on-site production, and make adjustments.
Description
technical field [0001] The invention relates to the technical field of iron and steel metallurgy, in particular to a roll gap control method based on mechanical parameters on a segmented model of a rolling interface. Background technique [0002] With the rapid development of my country's economy, the process of transformation from traditional industries to new industries is accelerating, and the technological level of industries such as automobile manufacturing, aerospace, and precision instruments is increasing day by day, and the demand for high-quality hot-rolled plates and strips in various industries has also increased significantly. . In actual production, there are still many problems. For example, surface quality problems of plate and strip products caused by rolling mill vibration. Continuous, high-speed, heavy-duty and stable rolling are the ultimate goals of steel rolling production, but almost all rolling mill equipment cannot avoid the problems of rolling mill...
