一、铸轧一体化技术产生的背景 二次大战后,欧、美、日等发达国家的钢铁工业在本国政府特殊优惠政策扶持下,加上良好的外部环境,很快得到恢复并通过改扩建和新建迅速得到发展。生产规模至70年代中期达到顶峰。70年代中期以后,这些国家的钢铁工进入停滞和萎缩时期。 如何使钢铁工业走出困境?传统的工艺技术由于其 I. The Background of the Integrated Technology of Casting and Rolling After the Second World War, the steel industry in developed countries such as Europe, the United States, Japan and other developed countries supported by the special preferential policies of their own governments, coupled with a good external environment, was quickly restored and expanded through reconstruction And newly built rapidly developed. The scale of production peaked in the mid-1970s. After the mid-1970s, steelworkers in these countries entered a period of stagnation and contraction. How to make the steel industry out of the woods? Because of its traditional technology
