在连续浇铸过程中,对大包到中包之间的钢流采用无氧化保护浇铸措施,是提高铸坯和钢材质量的有效途径。特别是对含铝量高的深冲钢、硅钢和低合金钢等品种的连铸生产,更是必要的工艺条件。为了解决连铸生产中大包到中包的钢流保护浇铸问题,第二炼钢厂和钢铁研究所合作,从1981年起在参考国外保护浇铸技术和设备的基础上,开始对此课题进行研究,并列为公司近几年来重点科技攻关项目之一。1984～1986年经多次试验,终于成功地研制
In the continuous casting process, the package to the middle of the steel flow between the non-oxidation protection casting measures is to improve the quality of slab and steel an effective way. In particular, the high content of aluminum deep-drawn steel, silicon steel and low alloy steel and other varieties of continuous casting production is even more necessary process conditions. In order to solve the problem of steel flow protection and casting in large package to medium package in continuous casting, the second steelworks cooperated with the Institute of Iron and Steel and started to carry out this project based on the reference of foreign protection casting technology and equipment since 1981 Research, tied for the company in recent years one of the key scientific and technological projects. 1984 to 1986 after many tests, and finally successfully developed
