一、概述连续铸钢是50年代以来,冶金工业得以迅速发展的一项新技术,深受各工业发展国家的重视。1986年全世界的钢产量虽有下降,但连铸坯的产量却增至32400万吨,比1985年增长了2.2％;连铸比从1985年的49.9％提高到52.0％。一些主要产钢国家的连铸比已达90％以上,不少著名钢厂已实现全连铸。我国已把大力发展连铸工艺作为钢铁工业的一项重要技术政策,应用连铸技术乃是
I. Overview Continuous casting is the steel industry since the 1950s, the rapid development of metallurgical industry is a new technology, by all industrial development countries attention. Although the world’s steel output dropped in 1986, the output of slab increased to 324 million tons, an increase of 2.2% over 1985; the continuous casting ratio increased from 49.9% in 1985 to 52.0%. Some major steel producing countries has reached more than 90% continuous casting ratio, many well-known steel mills have achieved full continuous casting. China has made great efforts to develop continuous casting process as an important steel industry policy, the use of continuous casting technology is
