唐山钢厂炼钢车间于今年2月28日在20吨/时的化铁炉上试用了热风操作。根据初步使用情况统计,使用热风操作可较正常提高30°～40℃(正常为1370～1380℃),而且风口便于维护不易结渣。试用情况如下:(1)热风使用情况:新开炉前20炉效果最好,以后由于抽气孔被焦炭堵塞,效率渐低。热风温度:最高270℃,一般180～210° ,最低50～90℃。热风燃烧室温度:最高1000℃,一般800～750℃,最低250～350℃。
Tangshan Iron and Steel Works steel plant on February 28 this year in the 20 tons / hour of iron stove trial hot air operation. According to preliminary usage statistics, the use of hot air operation can be increased more than normal 30 ° ~ 40 ℃ (normal 1370 ~ 1380 ℃), and the outlet is easy to maintain easy to slag. Trial conditions are as follows: (1) hot air usage: the best 20 furnaces before the new open the best, because after the exhaust hole is blocked by coke, the efficiency is getting lower. Hot air temperature: up to 270 ℃, generally 180 ~ 210 °, the lowest 50 ~ 90 ℃. Hot air combustion chamber temperature: up to 1000 ℃, usually 800 ~ 750 ℃, the lowest 250 ~ 350 ℃.
