中文摘要:

击碎那的团结发生在 1Cr13 不锈钢的连续的扔期间有或没有期末考试被调查电磁激动人心(F-EMS ) 。裂开的结果表演开始并且宣传碳和硫的元素被充实的谷物边界。最后的 stirrer 应该适当地被放在是离开新月的 7.5 m 的一个地点,并且在激动人心的地区的液体核心的适当厚度是 50 公里。当 250 A 的激动人心的水流被强加,它能支持 columnar-equiaxed 转变,减少第二等的树突手臂间距,和还原剂碳和硫的分离。F-EMS 能有效地减少在 1Cr13 不锈钢的裂缝的数量。

英文摘要:

Solidification cracking that occurs during continuous casting of 1Cr13 stainless steel was investigated with and without final elec- tromagnetic stirring (F-EMS). The results show that cracks initiates and propagates along the grain boundaries where the elements of carbon and sulfur are enriched. The final stirrer should be appropriately placed at a location that is 7.5 m away from the meniscus, and the appropri- ate thickness of the liquid core in the stirring zone is 50 ram. As a stirring current of 250 A is imposed, it can promote colurnnar-equiaxed transition, decrease the secondary dendrite arm spacing, and reduce the segregation of both carbon and sulfur. F-EMS can effectively de- crease the amount of cracks in 1Cr13 stainless steel.
