摘要
在连铸过程中,由于受多种因素的影响,钢坯表面会不可避免地形成周期性排列的横裂纹,如果这些横裂纹能在轧制中消失,将会大大提高生产效率和经济效益。通过DEFORM-3D软件和实验室轧制模拟了棒材轧制过程,分析了孔型对钢坯表面横裂纹的影响,得到了钢坯表面横裂纹在棒材轧制过程中的演变规律。
Affected by many factors in the billet continuous casting,periodic transverse cracks on the surface of the billet is formed inevitably.If these transverse cracks can disappear in rolling process,the production efficiency and economic benefit will be greatly improved.The effect of pass on surface transverse crack was analyzed by DEFORM-3 Dsoftware and laboratory simulation of bar rolling process.The evolution law of surface transverse cracks in bar rolling process was obtained.
