前言连续铸钢从六十年代得到迅速发展以来,以其显著的经济效果,促使钢材生产部门直接采用连铸坯作原料生产板材和型材。近年来,随着连铸工艺的日趋完善,连铸钢种的增多与铸坯质量的改善,各种类型的无缝钢管机组也已陆续地采用连铸坯生产管子,同时进行了广泛的研究工作。一九七二年首钢和包钢共同承担了冶金部下达的“连铸坯生产无缝钢管的工艺研究”的科研课题,其目的在于探索直接采用连铸圆坯在自动轧管机组上生产无缝钢管的工艺特点,并为大批生产提供直接经验。我们于七三年九月进行了第一次小批量
Preface Continuous casting steel has been rapidly developed since the 1960s, with its significant economic effect, prompted the steel production sector to use continuous casting slabs as raw materials for the production of sheet metal and profiles. In recent years, with continuous improvement of continuous casting process, continuous casting steel grades and improvement of slab quality, various types of seamless steel pipe units have successively adopted continuous casting slab production pipelines and conducted extensive research jobs. In 1972, Shougang and Baotou Steel jointly assumed the research project of “Research on Process of Seamless Steel Tube Production for Continuous Casting Billet” issued by the Ministry of Metallurgy. The purpose of this project was to explore the direct production of continuous round billet on automatic tube rolling mill Steel pipe process characteristics, and for large-scale production to provide direct experience. We conducted the first small batch in September 1993
