Abstract

Abstract

The carbon amount of unused pulverized coal in dust and sludge during the industrial experiment of Changcun coal in Baosteel's 1^# blast furnace (BF) was investigated by microscopic and chemical analysis. The carbon amounts of s udge and dust and of unused coal were determined in the condition that the mass fraction of Changcun coal was about 20%-40%. culated in different conditions of pulverized coal injection in The utilization ratio of pulverized coal was cal Baosteel's BF.
