Abstract

The invention discloses a method for calculating and predicting the tensile strength of hot-rolled wire rods. The measured value of carbon equivalent and the change of the average value of steel types are set as independent variables; the statistics and sorting of the measured values ​​of tensile strength of various steel types and the change of the average value are set as dependent variables; the mathematics of carbon equivalent and tensile strength is established Relational formula to obtain the regression equation; correction processing to obtain the optimal regression equation; use the established optimal regression equation of carbon equivalent and tensile strength to calculate and predict the change of tensile strength of hot-rolled wire. The invention provides technical support for the selection, design and process preparation of new steel products through the prediction of the tensile strength of the hot-rolled wire rod.

Description

A method for calculating and predicting tensile strength of hot-rolled wire rods technical field The present invention relates to steel tensile strength calculation field, be specifically related to a kind of calculation and prediction of hot rolled wire tensile strength Judgment method. Background technique [0002] With the improvement of product design mechanical performance requirements, the number of new steel grades developed or introduced is also increasing. But due to Due to many factors, the information or data of these new steel grades cannot be obtained in time, which affects the selection, design and process of products. system has brought difficulties. Among the many performance indicators of steel, tensile strength is an important measure of the design and mechanical properties of hot-rolled wire products. To a certain extent, the index parameters determine the usability of the material. During the tensile test, the specimen is drawn from the beginnin...
