摘要
由于409L铁素体不锈钢的物理特性和稳定化元素的加入,使得连铸过程中存在水口堵塞、板坯宽度不稳定、柱状晶发达、板坯易断裂等问题。针对上述情况,不锈钢分公司炼钢厂针对该钢种凝固特点、高温物理特性、析出物析出行为等方面进行了研究,解决了409L钢种浇铸过程中的工艺问题,保证了产品的质量。
The SEN clogging,slab width variation, developed columnar crystals, and slab fracture of 409L steel are caused by special physical properties and stabilization element addition. The study of solidification, elevated temperature physical properties and precipitation of 409L was carried out. The preliminary solution was got to solve these technical problems, and the product quality was enhanced.
