早在1964～1972年,“日本三菱重工业公司即与日本研究与开发公司共同搞过连续炼钢,并申请了专利。此后又有若干改进。 1980年,他们又与广岛公司合作,共同开发了利用废汽车及其他废钢的连续炼钢法. 1981年3月,建起了能力为15t/h的连续炼钢机组,试验一直进行到1982年11月。效果良好。该机组经改造后,已成为能力为20t/h的工业生产线。这条生产线包括:废钢熔化、精炼、二次精炼与连铸。工艺流程大体如下:
As early as 1964-1972, "Mitsubishi Heavy Industries, Ltd., Japan, engaged in continuous steelmaking with Japanese research and development company and applied for a patent. Since then, there have been some improvements. In 1980, they worked with Hiroshima Corporation to jointly develop Continuous steelmaking using waste motor vehicles and other scrap steel In March 1981, a continuous steelmaking unit with a capacity of 15 t / h was built and the test was carried out until November 1982. The unit has been rebuilt and has been upgraded Become a capacity of 20t / h of the industrial production line.The line includes: scrap melting, refining, secondary refining and continuous casting.The process flow is as follows:
