摘要: 采用非线性有限元分析软件ABAQUS,通过建立的线材与轧辊的3维热机耦合模型,对钢厂82B钢(/%:0.79~0.86C、0.15~0.35Si、0.60~0.90Mn、≤0.030S、≤0.030P)φ20mm至φ16.5mm 4道次预精轧过程中轧件的温度场、应力-应变场和轧制力进行数值模拟和分析。结果表明,数值模拟结果与实测结果相符;预精轧过程轧件心部温度和表面温度的差值为~130℃;运用该模型对现场轧制过程中的前滑进行了分析,得出了影响前滑的因素主要有延伸系数、轧制孔型尺寸、轧制速度以及辊径与轧件厚度比值。

Abstract: The numerical simulation and analysis on temperature field, stress-strain field and rolling force for <I)20 mm to 616. 5 mm 4 pass pre-finishing rolling process of steel 82B (/% : 0.79-0.86C, 0.15-0.35Si, 0.60 -0.90Mn, ≤0.030S, ≤0.030P) at steelworks are carried out by using nonlinear finite element method analysis software ABAQUS and an established 3-demensional thermo-mechanical coupling model between wire and roller. Results show that the simulated results conform to the measured results ; The difference between center temperature and surface temperature of stock during pre-finishing rolling process is 130 ℃ ; and with using this model to analyze front-sliding during rolling at worksite, it is obtained that main factors to influence the front-sliding are elongation coefficient, rolling groove size, rolling speed and ratio between roll diameter and stock thickness.
