中国钢铁工业转型发展时期炼钢科技进步的展望
|
摘要
中国钢铁业经过30多年快速发展后已进入转型阶段,之后产量不再有较大增加、会停滞数年然后逐年减少。科技进步重点将转向进一步降低生产成本、提高资源利用效率、提高钢材品质性能、加强生态环境保护等方面。以转炉炼钢溅渣护炉、顶底复合吹炼、高废钢比炼钢、快速RH真空精炼、高级钢生产工艺技术等为例,对钢铁工业进入转型期后炼钢科技进步取得的进展和发展趋势进行了分析论述。
The Chinese steel industry has entered the transition period after more than 30 years of rapid development. In the transition period,output of steel will no longer have significant increase,become stagnate for several years and then start to decrease. Emphasis of the R & D will shift to minimizing production cost,enhancing utilization efficiency of natural resources,raising properties of steel products,improving environment protection,etc. In this article,by taking examples of technologies of slag splashing,top and bottom combined blowing,high scrap ratio steelmaking,fast RH degassing,high grade steel production,etc,progress of steelmaking technology achieved recently after the Chinese steel industry had entered in the transition period is discussed.
