本文第一部分阐述了为达到“七·五”规划要求的生铁增产目标可以有两个途径:一是使规划中准备新建的9座1200～4063m~3高炉及24座255～750m~3高炉的50%于1989年以前陆续建成投产。1990年正式发挥效益;二是通过改造配套使现有高炉利用系数普遍提高0.23。并且论述了全部依靠老厂挖潜、改造、扩建即可满足2000年预测钢、铁产量规模,不需另建新厂的观点。第二部分阐述中型高炉新建和大修改造的适当装备水平,根据现有300m~3及600m~3高炉设备能力,只要重点解决原料条件和更换或改造现有风机,分别将其护容到350m~3和750m~3,即可最大限度地发挥设备能力,提高生铁产量和降低能耗。
The first part of this article states that there are two ways to achieve the goal of increasing pig iron production in the “July 5” Plan: First, to prepare 9 new 1200-1263m3 blast furnaces and 24 255-750m3 blast furnaces 50% put into operation one after another in 1989. 1990 formally play an effective; the second is through the transformation of the existing blast furnace utilization coefficient generally increased 0.23. It also discusses the viewpoint of relying on the old factory to tap the potential, transform and expand to satisfy the forecast of the output of steel and iron in 2000 and not to build a new factory. The second part elaborates the proper equipment level for new and overhauled mid-sized blast furnaces. According to the existing capacity of 300m ~ 3 and 600m ~ 3 blast furnaces, as long as the key raw material conditions are resolved and the existing ones are replaced or rebuilt, 3 and 750m ~ 3, you can maximize the equipment capacity, improve pig iron production and reduce energy consumption.
