摘要/Abstract

摘要： 通过对钢厂高速线材热连轧过程的传热分析,借助ABAQUS软件建立了线材与轧辊的3维热机耦合模型,对42A钢(0.39%～0.46%C)从Φ16 mm精轧至Φ5.5 mm轧材的10道次精轧过程的温度场,应力-应变场和轧制力进行了模拟。得出精轧后轧件心部温度升高130℃,表面温度降低10℃,轧件降温主要是轧件的热辐射和水冷造成的。10道次轧制力的计算值与实测值的相对误差为1.88%～4.50%。

Abstract: The simulation of temperature field, stress-strain field and rolling force of stock during 10 passes finishing rolling process from Φ16 mm rolling to Φ5. 5 mm wire of steel 42A (0. 39% ~0. 46% C) has been carried out by analysis on heat transfer in high speed continuous rolling process at steel works and by means of established 3D thermo-mechanical coupling model between wire and roller with ABAQUS software. It is obtained that after finishing rolling the temperature of center of stock increases by 130 °C while the temperature of surface of stock decreases by 10℃ , which is caused by radiation of stock-self and water cooling. The relative error between calculated and measured value of rolling force in 10 passes is 1.88% -4. 50%.
