本期重点刊登了我省从原料到炼铁生产技术领域中,大中小型高炉精料、高风温以及其他强化冶炼的部分生产实践和科研成果。同时节选了兄弟省小高炉使用球式热风炉的经验,《四川冶金科技情报简讯》第14期还介绍了国内外高炉炼铁和直接还原技术发展概况,从而清楚地看到了我省的差距。炼铁生产的目标是:优质、高产、低消耗、低成本。在质量第一的前提下,降低焦比(燃料比)是中心,而成本是衡量生产效果的综合指标。1978年12月攀钢高炉利用系数达到1.516,焦比降到629公斤,1979年3月重钢高炉利用系数达到1.213,焦比下降
This issue focuses on the province from raw materials to iron and steel production technology, medium and small blast furnace concentrate, high wind temperature and other intensive smelting part of the production practices and scientific research. At the same time excerpts from the experience of using blast furnaces in small blast furnaces in other provinces, the 14th edition of “Briefing of Sichuan Metallurgical Science and Technology Information Bulletin” also introduced the general situation of blast furnace ironmaking and direct reduction technologies at home and abroad, so as to clearly see the gap in our province. Ironmaking production goal is: high quality, high yield, low consumption, low cost. In the premise of quality first, to reduce the coke ratio (fuel ratio) is the center, and cost is a measure of the comprehensive effect of production. December 1978 Panzhihua blast furnace utilization factor reached 1.516, coke ratio dropped to 629 kilograms, March 1979 heavy steel blast furnace utilization factor reached 1.213, coke ratio decreased
