根据我国国民经济发展的需要,热宽带钢需求量必然不断增长,于是存在热宽带钢轧机如何改造和新建的问题。本文介绍了当前国内外热宽带钢轧机的发展情况,根据已有资料分别从生产能力、轧机布置的改进及新技术的应用,半连轧机的再受重视,节能措施及分期建设等方面进行了探讨。认为不必采用全连或四分之三连轧,应研究采用紧凑布置轧机方案,用盘卷箱等新设备,用热装、直接轧制和分期建设的办法,以节约投资而获得最好的经济效益。
According to the needs of our country’s national economic development, the demand for hot broadband steel is bound to continue to grow, so there is a problem of how to reform and build new hot-strip mills. This paper introduces the current development of hot strip mill in China and abroad. According to the existing data, we have carried out the research on production capacity, the improvement of mill layout and the application of new technology, the re-emphasis of semi-continuous rolling mill, energy saving measures and staging construction Discussion. Considering that it is not necessary to adopt all-aluminum or three-quarter rolling, research should be conducted on the use of a compact mill layout, the use of new equipment such as coil boxes, hot-fill, direct rolling and staged construction to save money and obtain the best Economic benefits.
