冶金企业是耗能大户,为了节能,世界各国钢铁企业都采用各种新技术以减少能源消耗,而连续铸钢是冶金行业采用的节能新技术之一。它的特点是改变传统的铸锭—开坯工艺,将冶炼合格的钢水通过连铸机连续浇铸成接近最终产品形状的铸坯,从而减少中间加工工序,降低金属损失和能耗。据1984年国际钢铁协会技术委员会对109个钢铁企业调查的结果表明,连铸工艺与传统工艺相比每吨钢可节能20～50千克标准煤。
Metallurgical enterprises are energy-hungry. In order to save energy, various steel enterprises in the world adopt various new technologies to reduce energy consumption. Continuous casting is one of the new energy-saving technologies adopted by the metallurgical industry. Its characteristic is to change the traditional ingot - billet process, the smelting of molten steel through the continuous casting machine into the shape of the final product near the slab, thereby reducing the intermediate processing steps to reduce metal loss and energy consumption. According to a survey conducted by the International Iron and Steel Institute’s Technical Committee on 109 steelmakers in 1984, the continuous casting process can save 20 to 50 kilograms of standard coal per ton of steel compared to conventional processes.
