摘要
通过分析连铸坯在宽面形成的偏离角凹陷的形貌和形成机理,讨论了板坯偏离角凹陷产生的原因。为了避免这类缺陷的产生,除冶炼好钢水成分、控制钢中[S]、[P]含量外,还要选择性能好、与钢种相适应的保护渣,采用弱的冷却方式并调整好结晶器的各项工艺参数。
By analyzing the figuration and forming mechanism, the forming reasons for the deviation angle longitudinal dishing on wide side of the slab are discussed. In order to avoid this defaults, besides the final metal analysis, the contents of the sulfur and phosphor in steel are well controlled,the protecting slag that has good properties and in accordance with the steel grade should be applied, the weak type of cooling should be adopted,and the process parameters of the mould should be adjusted well.
