西冶新材料公司研制的十三五国家重点研发计划“高性能桥梁用钢”项目Q690qENH耐候桥梁钢配套焊接材料
顺利通过专家评审
 
        4月18日,十三五国家重点研发计划“高性能桥梁用钢” 项目Q690qENH耐候桥梁钢配套焊接材料研制技术评审会在成都隆重召开,重点研发计划相关单位宝钢股份中央研究院武汉分院、中铁大桥勘测设计院、中冶建筑研究总院有限公司、中铁宝桥集团有限公司、中铁九桥工程有限公司的专家与代表参加了会议,西冶新材料公司董事长周正带领公司领导及相关人员出席了会议。


        本次评审专家组由来自重点研发计划相关单位的资深专家组成,组长由宝钢股份中央研究院武汉分院副总工程师、教授级高级工程师缪凯(享受国务院津贴)担任,副组长由中铁大桥勘测设计院副总工程师、教授级高级工程师易伦雄担任。评审组听取了西冶新材料公司产品开发部部长何秀所做的《耐候桥梁钢Q690qENH配套焊接材料研制技术报告》,查阅了相关文件资料,经过提问、答辩,***后一致认定:
        西冶新材料公司用于Q690qENH耐候桥梁钢的三种焊接方法(手工焊条XY-J80QNH,埋弧焊丝+焊剂XY-S80QNH+XY-AF80QNH、XY-S80QNH+XY-AF85QNH,富氩气体保护焊实心焊丝XY-ER80QNH)五种焊接材料的所有技术指标,均达到了十三五国家重点研发计划“高性能桥梁用钢”项目及其国家示范工程应用Q690qENH耐候桥梁钢配套焊接材料的技术要求,并成功通过中铁宝桥(扬州)公司的焊接评定,为国家示范工程——江汉七桥提供了重要的技术支撑。


        “高性能桥梁用钢”项目于2017年列入国家重点研发计划,并纳入国家“十三五”重点科研项目,毛新平院士为团队负责人。项目涉及钢材和配套焊接材料研发、工程建造、服役评价等系列技术,旨在构建一整套国际先进的钢结构桥梁设计建造体系。江汉七桥作为国家重点研发计划“高性能桥梁用钢”项目的示范工程,将首次使用Q690qE钢板和首次采用全新结构,双向八车道设计,空间结构复杂、施工难度极大,建成后将成为一条跨越武汉汉江的国际知名桥梁,具有重大的示范效应。
        当前,我国桥梁行业由于受设计水平、材料制造、配套部件、应用技术等因素限制,与美日等先进国家还存在较大的的差距,耐候桥梁钢还处于萌芽阶段。据统计,我国公路钢结构桥梁占比不足1%,美国为35%,日本41%,法国85%。因此,在世界桥梁业流行着这样一句话:世界桥梁建设20世纪70年代以前看欧美,90年代看日本,21世纪看中国。
       本次Q690qENH耐候桥梁钢配套焊材的成功研制并顺利通过评审,极大地丰富和完善了西冶新材料公司桥梁系列焊材,与水电焊材、石化压力容器焊材共同构筑了公司的三大明星系列产品。另一方面,也标志着“高性能桥梁用钢”项目取得重要进展,钢材和焊材完成了研发,为我国耐候桥梁钢发展和桥梁建设事业提供了重要支撑。
