摘　　要：为防止常规ＣＡＳ－ＯＢ铝热法精炼钢水时［Ａｌ］ｓ和Ｔ［Ａｌ］过高而导致连铸时中间包水口 堵塞，对用Ａｌ－ＣａＯ处理钢水进行了实验结果表明：用Ａｌ－ＣａＯ脱氧能够同时降低钢中溶解氧、 总氧（１０×１０－６～３０×１０－６）和酸溶铝量（７×１０－６～１２×１０－６），并能控制钢中夹杂物的形态、数量和分布．Molten steel of high solube Al conten and total Al content can result in the tundish nozzle blockage in continuous casting when heated by Al with CAS-OB refining technology. Some experiments have been made to treat molten steel by Al-CaO complex. The results Show that deoxidization by Al-CaO complex can not only reduce [Al]s (10x 10-6-30x 10b,[O] (7x10-12x 10-6) and T.O content simultaneously, but also control the morphology, amounts and distribution of the remaining inclusions in the Steel.
