为适应目前国内小方坯连铸迅速发展的需要,包冶所和首钢共同协作,经过两年努力,研制成功了小方坯连铸结晶器喂丝机及其工艺,1981年12月份由冶金部钢铁司组织了鉴定。这项国内首次研究成功的方法,不仅解决了小方坯连铸添加稀土的设备和工艺,而且为连铸结晶器中进行钢液铝含量的定 In order to meet the current needs of the rapid development of continuous casting billet, Baoting and Shougang work together, after two years of hard work to develop a successful billet continuous casting mold feeding machine and its technology, in December 1981 by the metallurgical Department of Steel Division organized the identification. This is the first successful research in China, not only solved the billet rare earth added continuous casting equipment and technology, but also for the continuous casting mold for aluminum content of liquid steel
