三年多来,吴县钢铁厂小高炉一直坚持采用将刨花铁屑打成捆直接加入铁水包中,利用铁水潜热熔化的办法来增产生铁,目前每吨铁水已加到80公斤,几年来共为本厂增产生铁3000吨,节焦1700吨,增盈5万元。炉外增铁后只要铁屑加入量控制合适不会影响生铁质量。注意事项如下: 1.出铁前先将铁屑捆加入铁水包内予热,以防打炮。2.加入量应视铁水量、铁水温度和铁水成分而定。一般每吨铁水加100公斤铁屑,
For more than three years, the small blast furnace in Wuxian Iron and Steel Plant has always insisted on using the shaving iron filings to join the ladle directly into the ladle, and using the latent heat melting of hot metal to increase the production of iron. At present, it has been added to 80 kg per ton of hot metal, The factory increased production of 3,000 tons of iron, section coke 1700 tons, an increase of 50,000 yuan. As long as the addition of iron outside the furnace control of iron filings will not affect the quality of pig iron. Matters needing attention are as follows: 1 iron before the iron scrap bundles into the hot metal to prevent fire. 2. The amount should be considered as hot metal, hot metal temperature and hot metal components may be. General per ton of molten iron plus 100 kilograms of scrap iron,
