在全国烧结工作者的共同努力下,近几年我国烧结工作取得很大进步。从表1可见各重点企业平均烧结主要指标逐年改善。含铁量、转鼓指数、碱度逐年提高,FeO逐年下降,作业率和利用系数逐年提高,固体燃料消耗逐年下降,总的趋势是朝着优质、高产、低耗迈进。与此相对应,高炉技术经济指标亦逐年改善。
With the joint efforts of sintering workers nationwide, great progress has been made in our sintering work in recent years. It can be seen from Table 1 that the major indicators of average sintering of key enterprises are improving year by year. Iron content, drum index, alkalinity increased year by year, FeO decreased year by year, operating rate and utilization coefficient increased year by year, solid fuel consumption decreased year by year, the general trend is towards high quality, high yield, low consumption forward. Corresponding to this, blast furnace technical and economic indicators have also been improved year by year.
