| 摘 要： | 对连铸结晶器振动过程进行了有限元模拟,获得了结晶器振动过程连铸坯表层应力分布,分析了结晶器锥度、结晶器与连铸坯间摩擦系数、拉速和连铸坯厚度对连铸坯表层应力分布的影响。振动过程结晶器末端附近区域连铸坯表层出现应力集中。随结晶器锥度减小和连铸坯宽度增加,连铸坯表层最大应力增加;拉速和连铸坯与结晶器间摩擦对连铸坯表层最大应力影响很小。研究结果对分析和认识连铸坯表面振痕的产生原因和结晶器磨损具有指导作用。

| Abstract: | The vibrating process of crystallizer during continuous casting was carried out by using the finite element method,and the stresses near slab surface at different stages were analyzed under various taper ratios of crystallizer,friction coefficients between crystallizer and slab,pulling speeds of slab,and slab widths.Results show that the stress concentration appears in the slab surface near the tail end of crystallizer.The maximum stress in slab surface increases with decreasing the taper ratio of crystalli... |
