采用80年代出现的成熟的新技术,改造现有热带钢轧机或新建高质量、多品种、高产量的热带钢连轧机,是发展我国钢材生产的有效途径。改造现有轧机费用仅为新建轧机投资的6～13%,产量可增加30～50%;新建轧机投资为常规热带钢轧机投资的1.2～1.3倍,而产量可为常规轧机的1.5～2.0倍。我国现有及正在建的热带钢轧机是满足不了国民经济发展需要的,必须加以改造,并且再上一套生产能力为1100万t的热带钢轧机。
It is an effective way to develop the steel production in our country by adopting the mature new technology appearing in the 80’s to transform the existing hot strip mill or to build a new high quality, multi-variety and high-output hot strip mill. The cost of retrofitting existing mills is only 6-13% of the investment in new mills and the output can be increased by 30-50%. The investment in new mills is 1.2-1.3 times that of conventional hot-strip mills and the output can be 1.5-2.0 times that of conventional rolling mills . The existing and under construction of the hot strip mill in our country can not meet the needs of the development of the national economy and must be rebuilt. A hot strip mill with a production capacity of 11 million tons should be rebuilt.
