武钢4高炉在渣量500kg/tFe左右实现了不放上渣作业。本文简要地介绍了不放上渣生产操作上采取的措施。并通过计算分析,论证了4高炉在现有生产条件下不放上渣工艺的合理性及效果。生产实践证明4高炉不放上渣,不仅可提高产量53～75t/d,降低焦比62～17.3kg/tFe,提高一类铁种3.8％左右,而且还改善了炉前的工作环境,减轻了工人劳动强度。
WISCO 4 blast furnace slag in the amount of about 500kg / tFe do not put slag operations. This article gives a brief introduction of the measures taken without slagging production operations. And through the calculation and analysis, it proves the reasonableness and effect of 4 blast furnaces not putting slag technology under the existing production conditions. Production practice has proved 4 blast furnace without slag, not only can increase the output 53 ~ 75t / d, reduce the coke ratio 62 ~ 17.3kg / tFe, improve a class of iron about 3.8%, but also improve the working environment in front of the furnace, reduce The labor intensity of workers.
