繼今(jin)年4月(yue)(yue)(yue)、6月(yue)(yue)(yue)兩(liang)次刷(shua)新(xin)世(shi)界紀錄(lu)(lu)后，11月(yue)(yue)(yue)份(fen)，中(zhong)冶(ye)(ye)實久承建的武(wu)鋼七號(hao)3200立方米高(gao)(gao)爐又以月(yue)(yue)(yue)利(li)用(yong)(yong)系數2.940t/m3.d的成績再次創(chuang)造新(xin)的世(shi)界紀錄(lu)(lu)。日前(qian)，中(zhong)國(guo)金屬學會在《中(zhong)國(guo)冶(ye)(ye)金報》推出的全國(guo)鋼鐵生產經(jing)濟技術指(zhi)標“排行(xing)榜”中(zhong)，武(wu)鋼煉鐵廠(chang)以大型高(gao)(gao)爐利(li)用(yong)(yong)系數位(wei)居榜首(shou)。
2004年12月17日(ri)，中冶實久開(kai)始(shi)武(wu)(wu)鋼(gang)七(qi)號高(gao)爐本(ben)體工(gong)(gong)(gong)(gong)(gong)程建設，歷時558天(tian)(tian)，比(bi)合同(tong)工(gong)(gong)(gong)(gong)(gong)期提前(qian)12天(tian)(tian)完(wan)成(cheng)全部(bu)建設任(ren)務，創(chuang)(chuang)造國內同(tong)類(lei)型高(gao)爐施工(gong)(gong)(gong)(gong)(gong)的(de)(de)最(zui)短工(gong)(gong)(gong)(gong)(gong)期，高(gao)爐本(ben)體工(gong)(gong)(gong)(gong)(gong)程被湖北省(sheng)冶金建設工(gong)(gong)(gong)(gong)(gong)程質量(liang)監(jian)督(du)站、冶金工(gong)(gong)(gong)(gong)(gong)業工(gong)(gong)(gong)(gong)(gong)程質量(liang)監(jian)督(du)總站武(wu)(wu)鋼(gang)監(jian)督(du)站評為武(wu)(wu)鋼(gang)結構(gou)優(you)質工(gong)(gong)(gong)(gong)(gong)程。2006年6月28日(ri)，武(wu)(wu)鋼(gang)七(qi)號高(gao)爐投產(chan)(chan)(chan)，至7月2日(ri)，高(gao)爐利(li)用系(xi)數達(da)(da)到2.0t/m3.d，實現(xian)日(ri)產(chan)(chan)(chan)鐵水6400噸，比(bi)設計(ji)要求的(de)(de)7天(tian)(tian)達(da)(da)產(chan)(chan)(chan)目標提前(qian)3天(tian)(tian)，創(chuang)(chuang)造同(tong)類(lei)型高(gao)爐達(da)(da)產(chan)(chan)(chan)的(de)(de)最(zui)快記(ji)錄。
據悉，武鋼(gang)煉(lian)鐵(tie)(tie)(tie)廠(chang)還在爐(lu)(lu)前(qian)科學管(guan)理，不斷摸(mo)索(suo)適宜的炮(pao)泥強度的同時(shi)，調整出(chu)鐵(tie)(tie)(tie)間隔時(shi)間及鉆頭大小，結合廠(chang)調度室的配(pei)(pei)罐(guan)情況，將出(chu)鐵(tie)(tie)(tie)次(ci)數由(you)原來的每天(tian)(tian)13-14次(ci)減少(shao)為每天(tian)(tian)12次(ci)，鐵(tie)(tie)(tie)次(ci)的減少(shao)，緩解了(le)(le)七號(hao)高爐(lu)(lu)配(pei)(pei)罐(guan)的困難，也有(you)利于渣鐵(tie)(tie)(tie)的及時(shi)排放。有(you)效的措施確(que)保了(le)(le)七號(hao)高爐(lu)(lu)爐(lu)(lu)況穩定順行。11月份，七號(hao)高爐(lu)(lu)平均日產鐵(tie)(tie)(tie)水9406.8噸。武鋼(gang)煉(lian)鐵(tie)(tie)(tie)廠(chang)依(yi)靠技(ji)術(shu)創新，促進了(le)(le)號(hao)高爐(lu)(lu)屢建奇功，推(tui)動了(le)(le)武鋼(gang)煉(lian)鐵(tie)(tie)(tie)技(ji)術(shu)走向世界領先水平。
