摘要: 调查了连铸工序敞浇因素对冷轧板“孔洞”缺陷的影响,结果表明大包敞浇时间过长 (≥ 16min),可使冷轧成品中的“孔洞”缺陷率明显提高。敞浇时若有多种连铸异常操作因素同时作用,可使连铸坯中的夹杂量增加,对应的成品更容易出“孔洞”。

Abstract: Effect of casting factors in continuous casting process on “cavity” defect of cold rolled sheet is investigated.It is concluded that longer ladle casting time (≥16 min) will obviously increase the “cavity” defect rate in the cold rolled products.Under open casting,if various anomalous operation factors act at same time,the amount of inclusion in continuous cast slab will be increased to form more “cavity” defects in the products.
