全国炼铁高炉有效容积利用系数比去年有很大降低,今年1月到8月,每炼一吨铁所占用的高炉有效容积,全国平均比1954年减少了4.7％以上。至此,炼铁工业中的这一项主要经济技术指标,已超过了第一个五年计划所规定的水平。目前,广大炼铁工人正继续挖掘潜力,争取进一步降低这项指标。我国高炉利用系数的降低,表示着炼铁工人用同样的高炉炼出了更多的生铁。在今年头八个月内,全国炼铁厂降低高炉利用系数的 The effective volume utilization factor of the nationwide ironmaking blast furnace has dropped significantly from last year. From January to August this year, the effective volume of blast furnace occupied by one ton of iron per refining decreased by 4.7% or more over the national average in 1954. At this point, the iron and steel industry in this one major economic and technical indicators, has exceeded the level of the first five-year plan. At present, the majority of iron-making workers are continuing to tap the potential and strive to further reduce this indicator. The reduction of utilization factor of blast furnace in our country indicates that the iron-smelters used more of the same blast furnace to produce more pig iron. In the first eight months of this year, the national ironworks reduced the blast furnace utilization factor
