日前 ,湖北大冶特钢集团高炉、2号连铸机、连轧二期工程等“三大工程”全面竣工。高炉工程投资 1 4 0 0 0万元 ,采用环型烧结机、富氧喷煤ＤＣＳ仪控系统等成熟的先进技术。高炉建成后 ,冶钢在国内特钢行业最先形成了铁水红送热装工艺路线 ,既优化冶炼工艺、大幅降低生产成本 , Recently, Hubei Daye Special Steel Group blast furnace, No. 2 continuous casting machine, rolling two projects such as “three major projects” fully completed. Blast furnace project investment 140 million yuan, the use of ring sintering machine, oxygen-rich coal injection DCS control system, and other mature advanced technology. After the completion of the blast furnace, the rule of steel in the domestic steel industry was the first to form a hot metal red hot charging process line, both to optimize the smelting process, significantly reduce production costs,
