向连铸结晶器内喂入金属丝是近年内出现的一项新技术.根据不同需要喂入稀土、铝、钙、钛、铁等丝状物,可作为补充脱氧、合金化、改善凝固组织、控制夹杂物形态以提高连铸钢材性能的有效手段.为适应国内连铸工艺技术发展和改善连铸钢质量的实际要求,首钢和包头冶金研究所在首钢试验厂的小方坯连铸机上做了向结晶器内喂入混合稀土金属丝和铝丝的工业性试验.经过两年来的开发
Feeding wire to continuous casting mold is a new technology emerging in recent years.According to the different needs of feeding rare earth, aluminum, calcium, titanium, iron and other filaments, can be used as supplementary deoxidation, alloying, to improve the solidification organization , To control the morphology of inclusions to improve the performance of continuous casting steel effective means.In order to meet the domestic continuous casting process technology development and improve the quality of continuous casting steel, Shougang and Baotou Metallurgical Institute in Shougang pilot plant billet caster Made to the mold mixed with rare earth metal wire and aluminum wire industrial test. After two years of development
