2007年我国重点钢铁业平均喷煤比为137kg/t,比上年度提高2kg/t,创出我国历史最好水平;长钢喷煤比为192kg/t,宝钢集团为186kg/t,武钢为173kg/t,太钢为162 kg/t,尚有两个企业没有喷煤,有5个企业年喷煤比低于100 kg/t。这说明,我国高炉喷煤处于多层次阶段,尚有较大的提升潜力。
In 2007, the average ratio of coal injected by China’s key steelmakers was 137kg / t, up 2kg / t from the previous year, setting the highest level in history in our country. The coal injection ratio for long steel was 192kg / t, that for Baosteel Group was 186kg / t, 173kg / t, TISCO is 162kg / t, there are two companies did not PCI, five enterprises in the coal injection rate of less than 100kg / t. This shows that China’s blast furnace coal injection at a multi-level stage, there is still greater potential for improvement.
