【摘要】 根据岩相显微分析和化学分析的结果,计算了宝钢1#高炉在进行常村贫煤工业实验时炉尘中未消耗煤粉中的含碳量,确定了常村煤的加入量在20%～40%的条件下炉尘中的含碳量和未消耗煤粉含碳量.给出了宝钢高炉在不同喷煤条件下煤粉在高炉内的利用率.更多还原

【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 sludge and dust and of unused coal were determined in the condition that the mass fraction of Changcun coal was about 20%～40%. The utilization ratio of pulverized coal was calculated in different conditions of pulverized coal injection in Baosteel’s BF.更多还原
