1.绪言 近年来炼钢技术的进步是非常惊人的,无论是转炉炼钢或电炉炼钢都有许多新技术被采用,在目前无论那种场合都有200-300T的炉子在开动,而且400T的炉子现在也已经运转,连铸技术也在普及,在工序的合理化和生产率的提高方面正在发挥着重大的作用。 一方面,在本世纪中叶,把炼钢 1. INTRODUCTION Advances in steelmaking technology in recent years have been phenomenal. Many new technologies have been adopted in converter steelmaking or electric steelmaking. At present, 200-300T furnaces are in operation at any one occasion, and 400T Of the furnaces are now running and continuous casting technology is also gaining ground and is playing a major role in rationalizing processes and improving productivity. On the one hand, steelmaking is to be made by the middle of this century
