In recent years at iron - making plant of pangang , the coke ratio of pig iron has reduced evidently by insisting on “ burden preparation ” course , improving quality of sinter , raising wind temperature , increasing rich oxygen quantity and injecting abundant pulverized coal into bf . the solid fuel consumption of sinter has been decreased greatly through insisting on using high - quality calces , practising high feed sintering , actualizing many techniques in solving key problems . at the same time , the energy source base management has been strengthened , and energy - saving work has made great progress , profits generated by energy - saving have exceeded a hundred million yuan 近年煉鐵廠通過堅持“精料”方針,改善燒結(jié)礦質(zhì)量,提高風(fēng)溫,增大富氧,實施大噴煤,使入爐焦比有明顯下降;燒結(jié)堅持用好生石灰,推行厚料層燒結(jié),實施多項技術(shù)攻關(guān),固體燃耗大幅度下降;同時加強能源基礎(chǔ)管理,節(jié)能工作取得長足進(jìn)步,節(jié)能創(chuàng)效益1億元以上。
