截至1978年1月为止,世界上已投产和正在兴建的连铸机共875台,2519流,其中方坯连铸机478台,1546流;板坯237台,379流;初轧坯160台,594流。近年来,连铸技术有显著发展,主要有:1.为提高钢水质量,采用各种钢液予处理技术,如真空脱气、钢包净化、用铝脱氧和喷石灰粉等。2.防止处理后的钢水再次氧化,在浇包和中间罐之间采用各种形式的封闭浇
As of January 1978, the world has put into operation and are under construction a total of 875 caster, 2519 stream, of which 478 billet caster, 1546 stream; slab 237, 379 flow; initial slab 160 , 594 stream. In recent years, continuous casting technology has been significantly developed, are: 1. In order to improve the quality of molten steel, using a variety of molten steel pretreatment technology, such as vacuum degassing, ladle purification, with aluminum deoxidation and spray lime powder. 2. To prevent the treated molten steel oxidation again, between the ladle and the intermediate tank using various forms of closed pouring
