日本钢铁工业由于连铸比的增加,工序的连续化和工序全面管理,使十年来的节能工作有了显著进步.高炉等用煤代替重油,使1985年的用油量比1973年减少了86%。但是,随着最近钢铁生产发展速度的下降、设备利用率的降低和产品的优质化、多样化,估计在能源消费方面不会有很大的降低。 Japan’s steel industry has made significant improvements in energy conservation over the past decade due to the continuous casting process, the continuous process and the overall management of processes. The replacement of heavy oil by coal, such as blast furnace, reduced the amount of oil used in 1985 by 86 %. However, with the recent slowdown in the development of steel production, lower equipment utilization and product quality and diversification, it is estimated that there will be no significant reduction in energy consumption.
