“十五”期间中国冶金工业科技进步主要方向有四大点 :第一　优化钢铁工业流程 ,节能降成本 ,提高经济效益 ;实现“炼钢———精炼———连铸———连轧”的技术改造 ,注重各工序间的生产匹配与协调 ,提高连浇炉数 ,充分发挥整条生产线的的生产能力 ,提高技术水平。使吨钢综合? During the Tenth Five-Year Plan, there are four main directions for the progress of science and technology in China’s metallurgical industry. The first is to optimize the industrial process of iron and steel industry so as to save energy and reduce costs and increase economic benefits. The “steelmaking --- refining --- continuous casting --- continuous rolling ”The technical transformation, pay attention to the matching between production and coordination of processes, improve the number of continuous casting furnace, give full play to the production capacity of the entire production line and improve the technical level. So tons of steel integrated?
