The Calculation Method of the Limit and Strain of the Strip Material Yield in Cold Rolling
Proposed a method of calculating the limit of yield strength and yield stress of the material strip in cold rolling. Taken into account when developing the methodology jointly influence the chemical composition of the wrought alloy, hardening, strain rate and temperature in the cold rolling on limit of yield strength and yield stress of the strip material. Presents data on quantitative effect of temperature and strain rate on the yield stress of the material strip in cold rolling. Shown that neglecting the influence of these factors leads to errors of up to 15 - 45% at forecasting yield stress for cold rolling mills. This article contains all the necessary data for the implementation of the proposed methodology for calculating the limit of yield strength and yield stress of the material strip in cold rolling, which gives reason to recommend it for practical application.
