七十年代后期,连铸生产发展迅速。由于转炉炼钢炉外精炼,连铸过程防止钢液二次氧化和高速连铸技术的进展,使连铸生产弱氧钢(或称标准沸腾钢)成为可能,从而为扩大连铸生产品种,特别是为可以生产各类品种的全连铸车间提供了保证。因为连铸 The late seventies, continuous casting production developed rapidly. As the converter outside the furnace refining, continuous casting process to prevent secondary oxidation of molten steel and high-speed continuous casting technology, continuous casting production of weak steel (or standard boiling steel) as possible, so as to expand the production of continuous casting varieties, Especially for the production of various types of all-continuous casting plant provides a guarantee. Because of continuous casting
