冷铁两座100m~3高炉几年来生产进步较快,生铁产量有较大幅度提高,炼铁能耗大幅度下降。1984年实产生铁11.0944万吨,比最高年产量的1979年增长19.04%;燃料比降低144.5kg,创造了历史最好水平。生产改观的原因是多方面的,但根本原因是实行了一系列技术改造措施,其中主要有以下几方面。一、改善原料质量长期以来,我厂高炉主要用外购矿,来源广、质量差,给生产带来了很大困难。在1977年实行了高架料仓和槽下筛分技术措施的基础上,对现有原料系统又进一步采取了 Cold iron two 100m ~ 3 blast furnace production in recent years improved rapidly, a substantial increase in pig iron production, iron smelter energy consumption dropped significantly. In 1984, iron production was 110,944 tons, an increase of 19.04% over the highest annual output in 1979; the fuel ratio was reduced by 144.5kg, creating the best record in history. There are many reasons for the improvement of production. However, the fundamental reason is that a series of technical renovation measures have been put in place, mainly in the following aspects. First, to improve the quality of raw materials For a long time, I plant the main use of outsourced blast furnace, a wide range of sources, poor quality, to the production of great difficulties. On the basis of the technical measures for sifting silos and troughs in 1977, the existing raw material system was further taken
