近日(ri)，中(zhong)國中(zhong)冶所屬中(zhong)國三冶集團有限公(gong)司承建(jian)的(de)鞍鋼8號JNX3-70-1型60孔7米焦爐項目開工。
鞍(an)鋼(gang)8號焦(jiao)(jiao)(jiao)(jiao)爐(lu)(lu)是(shi)(shi)(shi)(shi)(shi)鞍(an)鋼(gang)化工(gong)(gong)(gong)總廠焦(jiao)(jiao)(jiao)(jiao)爐(lu)(lu)四期(qi)改造(zao)工(gong)(gong)(gong)程的(de)重(zhong)點(dian)，被列為國家(jia)863計(ji)劃項目。該(gai)焦(jiao)(jiao)(jiao)(jiao)爐(lu)(lu)是(shi)(shi)(shi)(shi)(shi)中冶焦(jiao)(jiao)(jiao)(jiao)耐工(gong)(gong)(gong)程技(ji)術有限公司研(yan)發設計(ji)的(de)新(xin)一代60孔JNX3-70-1型(xing)7米(mi)(mi)焦(jiao)(jiao)(jiao)(jiao)爐(lu)(lu)，年(nian)產(chan)冶金焦(jiao)(jiao)(jiao)(jiao)炭75萬(wan)噸。與上一代相比(bi)，新(xin)焦(jiao)(jiao)(jiao)(jiao)爐(lu)(lu)擁有多(duo)項技(ji)術亮點(dian)：一是(shi)(shi)(shi)(shi)(shi)其(qi)炭化室(shi)寬(kuan)度大(da)(da)于500毫米(mi)(mi)，在(zai)7米(mi)(mi)級焦(jiao)(jiao)(jiao)(jiao)爐(lu)(lu)中最(zui)大(da)(da)；二是(shi)(shi)(shi)(shi)(shi)高爐(lu)(lu)煤氣(qi)采用(yong)(yong)三(san)段加(jia)(jia)熱(re)方式；三(san)是(shi)(shi)(shi)(shi)(shi)在(zai)燃燒(shao)室(shi)隔(ge)墻上又設置了兩段空煤氣(qi)出口；四是(shi)(shi)(shi)(shi)(shi)采用(yong)(yong)了大(da)(da)連重(zhong)工(gong)(gong)(gong)的(de)最(zui)新(xin)專利——大(da)(da)型(xing)7米(mi)(mi)推焦(jiao)(jiao)(jiao)(jiao)車（帶除塵(chen)(chen)裝置）。新(xin)焦(jiao)(jiao)(jiao)(jiao)爐(lu)(lu)不僅在(zai)爐(lu)(lu)體設計(ji)、焦(jiao)(jiao)(jiao)(jiao)爐(lu)(lu)機械﹑焦(jiao)(jiao)(jiao)(jiao)爐(lu)(lu)工(gong)(gong)(gong)藝等(deng)方面(mian)達到了國際先進水平，而且具有結(jie)構嚴(yan)密(mi)、加(jia)(jia)熱(re)均勻、熱(re)供效率(lv)高、投(tou)資省、壽命(ming)長(chang)等(deng)優點(dian)，投(tou)產(chan)后無煙、無塵(chen)(chen)、無味，多(duo)項指標達到綠色環保(bao)要求，是(shi)(shi)(shi)(shi)(shi)適合我國國情(qing)的(de)新(xin)一代大(da)(da)型(xing)焦(jiao)(jiao)(jiao)(jiao)爐(lu)(lu)。
中國三冶(ye)集團(tuan)在工(gong)(gong)程中主要承擔8號焦爐(lu)及(ji)(ji)煙道(dao)等砌筑工(gong)(gong)程、8號焦爐(lu)煉(lian)焦工(gong)(gong)藝的全部安(an)裝及(ji)(ji)焦爐(lu)熱態的施工(gong)(gong)任務。該焦爐(lu)預計于(yu)11月(yue)建成投產。
