Abstract

A carbon loss mathematical model was established based on the Fe–O–C balance and traditional engineering method. The coke carbon loss and carbon loss of coupled direct reduction are calculated based on this model and actual production data of B# blast furnace in Bayisteel. And then, the model is applied to research the effect of coal ratio, burden metallization rate, blast temperature, oxygen enrichment rate and blast humidity on carbon loss of direct reduction and carbon loss of coupled direct reduction. The results show that burden metallization rate and oxygen enrichment rate have significant influences on carbon loss of direct reduction. The burden metallization rate, oxygen enrichment rate and coal ratio have significant influences on carbon loss of coupled direct reduction. In addition, comparing with 4# blast furnace in Baosteel, the high-quality coke can observably reduce carbon loss of coupled direct reduction .
