日报《铁钢新闻》三月八日刊登题为《日本大钢铁公司炼钢技术革新》的综述文章,现摘要如下:以1973年的石油危机为转机,日本钢铁工业特别是大钢铁公司的技术战略,从以往的注重大量生产转向降低成本和提高质量。近来钢铁技术面貌有了很大改观,尤其是炼钢技术。炼钢技术变迁的特征,可以用“进入了搅拌技术时代”来表示。转炉复合吹炼法。此法是西德、法国、卢森堡、比利时、英国和日本在大体相同的时间内研制的。复合吹炼法具有降低低碳钢的生产成本、提高钢水收得率和使用废钢比例高、节省铁合金、减少渣量、钢中含氧量少、钢质清洁等优点,而且在现有顶吹转炉上改造,其投
The daily newspaper Iron Steel News published a review article titled “Technological Innovation of Steelworks in Japan’s Big Steel Industry” on March 8. The summary is as follows: Taking the 1973 oil crisis as a turning point, the technology of the Japanese steel industry, especially the big steel companies Strategy, from the previous emphasis on mass production to reduce costs and improve quality. Recently the face of steel has changed a lot, especially steelmaking. The characteristics of the steelmaking technology change can be expressed by “Entering the Age of Stirring Technology”. Converter compound blowing method. The law was developed by West Germany, France, Luxembourg, Belgium, the United Kingdom and Japan at about the same time. The compound blowing method has the advantages of reducing the production cost of the low-carbon steel, improving the yield of the molten steel and using the high proportion of the scrap, saving the ferroalloy, reducing the amount of slag, reducing the oxygen content in the steel, cleaning the steel, etc. Moreover, Converter transformation, its investment
