七十年代初期,国际上出现推广高炉汽化冷却的热潮.我国从1970年到1976年,据不完全统计,全国有8个厂15座大小高炉采用了汽化冷却(附表).可是到七十年代末,除首钢2号高炉外,大高炉不但没有发展,反而原来用汽化冷却的高炉,也多改回以水冷却.小高炉在缺水地区仍然坚持使用.目前,对于高炉汽化冷却的可行性问题,存在较大的争议.这里就鞍钢高炉汽化冷却实践的总结,谈谈个人对汽化冷却必要性和可行性的看法.
In the early 1970s, there was an international boom in the promotion of blast furnace gasification and cooling.China from 1970 to 1976, according to incomplete statistics, the country has 8 plants 15 size blast furnace using evaporative cooling (schedule), but to seventy In addition to blast furnace No. 2 at the end of the 1950s, large blast furnaces not only failed to develop, but instead the blast furnaces that were cooled by vaporization were also changed back to water for cooling. Small blast furnaces were still used in water-scarce areas. Sexual problems, there is a big controversy here to summarize the practice of the Anshan Iron and Steel Blast Furnace cooling to talk about the individual’s views on the necessity and feasibility of vaporization cooling.
