寶鋼“十五”重大項目
我國最大寬厚板工程“中國軋機之王”投產

　　由中冶集團寶冶建設承建的寶鋼“十五”重大項目5米寬厚板軋機一期工程已圓滿建成，于近期進行熱負荷試車獲得成功，軋出第一塊寬厚板。這項被稱為“中國軋機之王”的我國最大的寬厚板工程的建成投產，對提升我國綜合國力和國際競爭能力，具有重要的戰略意義。

　　寶鋼寬厚板軋機工程建在寶鋼一煉鋼區域內，鋼水由一煉鋼3座300噸轉爐經二次精煉后供應。工程分兩期建設，一期建設一架四輥可逆精軋機，一架立輥軋機，軋制最大寬度4.8米，長25米，厚150毫米，年產140萬噸寬厚板。二期增建一架粗軋機，生產規模擴展到180萬噸，最大軋制厚度可達400毫米。產品以船用板及管線板為主，同時還生產建筑、鍋爐容器、模具等國內緊缺鋼板品種，專用板約占90%左右。這項工程的建設將改變我國5米級造船用板，大口徑、長距離、高鋼級、抗硫化氫管線用板長期依賴進口的狀況。中國造船巨頭中國船舶工業集團公司已與寶鋼簽訂戰略合作協議，借助寶鋼的5米級寬厚板軋機造船板的供板能力，擴大造船規模和造船能級，其目標是今年將躋身世界造船業前5強，2010年進入前3強，至2015年成為世界第一造船集團。
