炉外喂钙丝与连铸水口堵塞的改善

Ca-Wire Feeding in Ladle and the Improvement of Submered Nozzle Stopping on Continuous Casting

针对连铸生产过程中水口堵塞现象，从炉外喂钙丝，改变非金属夹杂物形态，提高钢液洁净度，从而改善水口堵塞方面进行了分析研究．并论述了喂钙丝的主要控制参数及效果．为解决连铸水口堵塞问题提供了一条有效、经济的途径．

Studies on the changes of submerged nozzle stopping on the continuous casting has been carried out by Ca-wire feeding in ladle. The results showed that the form of non-metallic inclusions was changed and the molten steel was cleaner than before. Therefore the continuous casting was improved. The main factors and the effect of Ca-wire feedng were also discussed in this paper. It was a efficient and economical way to solve the problem of submerged nozzle stoppning on continuous casting.
