Method for predicting rolling force and thickness of each layer of cold-rolled metal composite plate

Abstract

The invention discloses a method for predicting the rolling force and the thickness of each layer of a cold-rolled metal composite plate, and belongs to the technical field of composite plate rolling.The method comprises the following steps that firstly, composite plate rolling process parameters are obtained; the roller radii of a soft metal plate blank and a hard metal plate blank used in the calculation of the rolling force of respective equivalent veneer rolling are set, and the total reduction rate of composite rolling, the reduction rates of the soft metal plate blank and the hard metalplate blank, and the outlet thicknesses at the reduction rates are calculated respectively; rolling force generated when the soft metal and hard metal plate blanks is rolled from the inlet thicknessto the outlet thickness in the equivalent veneer rolling process is calculated; whether the rolling force meets the convergence condition or not is judged, and if not, recalculation is conducted tillthe convergence condition is met; the rolling force during production of the bimetal cold-rolled composite plate is obtained; and the final outlet thicknesses of the soft metal and hard metal plate blanks are calculated. According to the method, the rolling force and the thickness of each layer of the cold-rolled metal composite plate are predicted, and the rolling force and the thickness of eachlayer obtained through calculation are basically close to actual values.

Description

technical field [0001] The invention relates to the technical field of composite plate rolling, in particular to a method for predicting the rolling force and the thickness of each layer of a cold-rolled metal composite plate. Background technique [0002] Metal layered composite materials can not only save a large amount of rare and precious metals, but also have the excellent characteristics of the base and clad materials, which can meet the special requirements of different environments and use conditions, and are widely used in electronic packaging, petrochemical, marine engineering, aerospace and other fields. The rolling composite method is a typical layered metal composite technology. The rolling composite method has high production efficiency, is easy to realize mass production, and can produce products with large length and width. The obtained products have good consistency and stable performance. Therefore, the rolling composite method Compounding method is widely...
