    西冶公司Q690qENH耐候橋梁鋼配套焊接材料 順利通過專家評審

    西冶新材料公司研制的十三五國家重點研發計劃“高性能橋梁用鋼”項目Q690qENH耐候橋梁鋼配套焊接材料
    順利通過專家評審
     
            4月18日,十三五國家重點研發計劃“高性能橋梁用鋼” 項目Q690qENH耐候橋梁鋼配套焊接材料研制技術評審會在成都隆重召開,重點研發計劃相關單位寶鋼股份中央研究院武漢分院、中鐵大橋勘測設計院、中冶建筑研究總院有限公司、中鐵寶橋集團有限公司、中鐵九橋工程有限公司的專家與代表參加了會議,西冶新材料公司董事長周正帶領公司領導及相關人員出席了會議。


            本次評審專家組由來自重點研發計劃相關單位的資深專家組成,組長由寶鋼股份中央研究院武漢分院副總工程師、教授級高級工程師繆凱(享受國務院津貼)擔任,副組長由中鐵大橋勘測設計院副總工程師、教授級高級工程師易倫雄擔任。評審組聽取了西冶新材料公司產品開發部部長何秀所做的《耐候橋梁鋼Q690qENH配套焊接材料研制技術報告》,查閱了相關文件資料,經過提問、答辯,***后一致認定:
            西冶新材料公司用于Q690qENH耐候橋梁鋼的三種焊接方法(手工焊條XY-J80QNH,埋弧焊絲+焊劑XY-S80QNH+XY-AF80QNH、XY-S80QNH+XY-AF85QNH,富氬氣體保護焊實心焊絲XY-ER80QNH)五種焊接材料的所有技術指標,均達到了十三五國家重點研發計劃“高性能橋梁用鋼”項目及其國家示范工程應用Q690qENH耐候橋梁鋼配套焊接材料的技術要求,并成功通過中鐵寶橋(揚州)公司的焊接評定,為國家示范工程——江漢七橋提供了重要的技術支撐。


            “高性能橋梁用鋼”項目于2017年列入國家重點研發計劃,并納入國家“十三五”重點科研項目,毛新平院士為團隊負責人。項目涉及鋼材和配套焊接材料研發、工程建造、服役評價等系列技術,旨在構建一整套國際先進的鋼結構橋梁設計建造體系。江漢七橋作為國家重點研發計劃“高性能橋梁用鋼”項目的示范工程,將首次使用Q690qE鋼板和首次采用全新結構,雙向八車道設計,空間結構復雜、施工難度極大,建成后將成為一條跨越武漢漢江的國際知名橋梁,具有重大的示范效應。
            當前,我國橋梁行業由于受設計水平、材料制造、配套部件、應用技術等因素限制,與美日等先進國家還存在較大的的差距,耐候橋梁鋼還處于萌芽階段。據統計,我國公路鋼結構橋梁占比不足1%,美國為35%,日本41%,法國85%。因此,在世界橋梁業流行著這樣一句話:世界橋梁建設20世紀70年代以前看歐美,90年代看日本,21世紀看中國。
           本次Q690qENH耐候橋梁鋼配套焊材的成功研制并順利通過評審,極大地豐富和完善了西冶新材料公司橋梁系列焊材,與水電焊材、石化壓力容器焊材共同構筑了公司的三大明星系列產品。另一方面,也標志著“高性能橋梁用鋼”項目取得重要進展,鋼材和焊材完成了研發,為我國耐候橋梁鋼發展和橋梁建設事業提供了重要支撐。
