1 前言新余钢铁公司炼铁厂6号高炉(600m~3)投产于1985年,经简易大修后于1997年2月开始了第二代炉役。在这之前焦比一直居高不下。1998年虽有所下降,但仍高达637kg/t。1999年依靠炼铁科技进步,重视精料,挖掘风温潜力,强化操作管理等手段,高炉指标取得了突破,见表1。全年平均人炉焦比521kg/t,比上年下降116kg/t,其中1999
1 Introduction Xinyu Iron and Steel Company Iron Works 6 blast furnace (600m ~ 3) put into operation in 1985, after a simple overhaul in February 1997 began the second generation of furnaces. Before this coke has been high. Although the decline in 1998, but still up to 637kg / t. In 1999, relying on the progress of iron and steel science and technology, focusing on fine materials, exploring the potential of air temperature and strengthening operation and management, a breakthrough was made in the blast furnace index (Table 1). The average annual furnace coke ratio 521kg / t, down 116kg / t over the previous year, of which 1999
