摘　　要：沸腾钢、半镇静钢的生产费用略低于连铸钢。建议一些有生产沸腾钢条件，特别有生产沸腾钢上铸条件的厂，可继续利用原有设备发挥其优势，而将有限的资金投向镇静钢改造连铸上。ince the operating cost for the rimmed and semi-rimmed steel is relatively lower than that for the continuous casting steel it is recommended that those that have capabilities of producing rimmedsteel,especially those having up casting ability should continue to bring into full play the superiorityof their existing equipments while putting their limited capital investment in the continuous casting for the killed steel.
