一、前言发展连铸是我国钢铁工业既定的一项重要技术政策,而以连铸为中心,增加连铸坯产量,提高铸坯质量,是保证提高经济效益的有力措施。近几年来,我国连铸生产发展迅速。武钢第二炼钢厂在七十年代末,建成了三台板坯连铸机。对连铸坯的生产采取了一系列的措施,使各种缺陷率不断下降,以提高连铸坯的产量和质量。但是,由于连铸机是新设备,采用新工艺、新技术,经历短,实践经验少,难免在
I. Preface The development of continuous casting is an important technical policy set by our country’s iron and steel industry. With continuous casting as the center, increasing the output of continuous casting slabs and improving the quality of slab is a powerful measure to ensure economic benefits. In recent years, China’s continuous casting production has developed rapidly. WISCO No.2 Steelmaking Plant built three slab caster in the late seventies. The continuous casting slab production has taken a series of measures to make various defect rates continue to decline in order to improve the production and quality of slab. However, due to the continuous casting machine is a new equipment, the use of new technology, new technology, experience short, less practical experience, inevitably
