半镇静钢和化学封顶沸腾钢采用快速浇注可以减少轧后废品和降低钢坯处理量。快速浇注法亦适合于浇注不重要的普通定货的镇静钢。在克里沃罗格冶金厂的平炉车间里采用实底钢锭模(长宽比1.16;高:宽=3.1;锥度38％),用上铸法把碳素镇静钢铸成8.5吨重的钢锭。铸沸腾钢采用两种矩形截面(k=8和113)座在单锭底板上的上小下大无底钢锭模;钢 Semi-killed steel and chemical-capped boiling steel with fast pouring reduce scrap and reduce billet throughput. Fast pouring method is also suitable for pouring unimportant ordinary ordered sedate steel. In the hearth workshop at the Krivoy Rogo Metallurgical Plant, a solid steel ingot mold (aspect ratio 1.16; height: width = 3.1; taper 38%) was used. The carbon killed steel was cast into an 8.5 ton ingot . Cast ingot steel using two rectangular cross-section (k = 8 and 113) seat in the single spindle base plate on the small bottom large bottomless ingot mold; steel
