一、前言连铸技术与模铸相比,具有节约能源、提高金属收得率等优越性,故在工业发达国家得到迅猛发展。目前,日本的连铸比已达到90%;西德达到77%;美国约占50%。我国的连铸技术起步并不晚,但直至1985年全国的连铸比仅有10.79%。为了改变这种状况,“七五”要求发展连铸生产,使连铸比达到30%。当前,世界不锈钢产量约为800×10~4t、 I. INTRODUCTION Continuous casting technology has the advantages of saving energy and increasing metal yield compared with molding. Therefore, it has been rapidly developed in industrialized countries. At present, Japan’s continuous casting ratio has reached 90%; West Germany reached 77%; the United States accounted for about 50%. China’s continuous casting technology started not too late, but until 1985 the proportion of continuous casting only 10.79%. In order to change this situation, “Seventh Five-Year” requires the development of continuous casting production, so that the continuous casting ratio of 30%. At present, the world stainless steel output is about 800 × 10 ~ 4t,
