目前国内外浇注沸腾钢除采用大型模拟提高生产能力外,还在提高成坯率和降低铸件消耗上不断探索,取得了不少成功经验,如采用瓶口模、ZF法、凹形底板等。攀钢自投产以来,浇注沸腾钢一直使用FX8.5敞口钢锭模。随着四号高炉的投产和转炉装入量扩大,钢铁生产大幅度增加。为解决FX8.5钢锭模浇钢容量偏小造成注余回炉的问题,在不改 At present, the domestic and foreign pouring boiled steel not only increases the production capacity by using large-scale simulation, but also continuously explores improving the blank-forming rate and reducing the consumption of castings. Many successful experiences have been obtained such as bottle die, ZF method and concave bottom plate. Panzhihua Iron and Steel since production, pouring boil steel has been used FX8.5 open ingot mold. With the fourth blast furnace put into operation and the converter into the expansion, steel production increased significantly. In order to solve the FX8.5 steel ingot die cast steel capacity is too small, the problem of excess injection furnace return, do not change
