滑板挡渣系统在安钢150t转炉上的应用

Application of skateboard type slag blocking system in 150 t converter in Angang Steel

简述了转炉挡渣工艺技术及滑板挡渣法的原理、结构和控制过程,并结合安阳钢铁集团公司150 t转炉滑板挡渣系统的应用,介绍了适应性改造的措施和实际效果。滑板挡渣工艺的应用有效地减少了回磷及出钢过程的下渣量,达到优化钢质,提高经济效益的目的。

The technological process of the converter slag blocking and the prlnclpte, structure and control process of the skateboard type slag blocking method are briefly de- scribed and the adaptable revamp measures and practical results introduces in connection with application of skate board type slag blocking system in the 150 t converter in Anyang Iron ＆ Steel Group Corporation. By application of the skateboard type slag bloc- king process phosphor pick-up is dramatically reduced and the amount of the outlet slag in tapping lowered as well and thus the steel quality is optimized and the purpose of im- provement in the economic efficiencies achieved.
