STUDY ON NUMERICAL SIMULATION OF CONTROLLED COOLING MEDIUM STEEL PLATE AND ANALYSIS ON ITS DEFORMATION

Abstract

Abstract: The basic theory of analyzing thermo-elasto-plastic behavior is described by finite-element method and the causes of transverse deformation are explained. Based on convective heat transfer boundary conditions of steel plates subjected to large density impingement jets, the thermal field of medium steel plate is computed numerically. And by the indirect coupling method of thermal stress, a mathematical model incorporating thermo-elasto-plastic behavior is developed to analyze the causes of plate deformation. Compared thermal stress with corresponding time-dependent temperature history, defective shapes can be prevented by the appropriate control of water flow ratio between top and bottom headers.

Key words: Controlled cooling, Finite element methood, Medium steel plate, Numerical simulation, Transverse deformation
