摘要
介绍了莱钢炼钢厂开发的第二代定径水口快速更换保护浇注技术的工艺措施以及在莱钢 3 #、4#连铸机的推广应用情况。该快换水口保护浇注工艺克服了塞棒控制工艺的不足 ,使钢水收得率由 95 .72 %提高到 99.60 % ,具有提高钢水收得率、减少耐材消耗、提高铸坯质量、稳定生产组织等优点。
The technology means of rapid change of second generation fixed diameter nozzle developed by Laigang Steelmaking Plant and protecting casting and popularized and applied conditions in No.3 and No.4 continuous casting machine of Laigang are introduced. The protecting casting technology of this rapid changing nozzle overcomes the deffciency of stopper control technology,so that the yield of liquid steel is increased from 95.72%to 99.60%. It has the advantages of improving the yield of liquid steel, reducing the consumption of refractory, increasing the quality of continuous casting slab and stabilizing the production organization, etc.
