在包钢历年炼钢产品的品种构成中,中高碳钢的比例一直大,一直是由平炉冶炼,转炉还不能冶炼。从“七五”计划开始,包钢炼钢的立足点要逐步转移到转炉上来,转炉如何既经济又可靠地冶炼中高碳钢成了实现这一转移中最关键的一步。这一问题的解决不仅直接涉及炉后精炼设备的选择,也将为包钢炼钢工艺未来的发展提供依据。本文提出
In the history of Baotou steel products in the composition, the proportion of high-carbon steel has been large, has been smelting by open hearth, the converter can not smelt. Starting from the “Seventh Five-Year Plan”, Baosteel’s steelmaking foothold should be gradually transferred to the converter. How to economically and reliably smelt medium and high carbon steel has become the most crucial step in realizing this shift. The solution to this problem not only directly relates to the choice of after-furnace refining equipment, but also will provide the basis for the future development of Baotou Steelmaking Technology.
