摘　　要：根据装配式钢结构住宅使用需求,采用低碳铜铬镍微合金成分体系包晶钢设计、近终型异型坯连铸技术、型钢万能轧制技术,自主开发了420 MPa级高强度厚规格耐候抗震专用热轧H型钢,该产品主要应用于钢结构住宅框架结构的立柱。通过连铸工艺及轧制工艺优化,解决了铸坯翼缘内侧皮下裂纹及中间裂纹,以及轧制过程中氧化铁皮压入带来的成品表面缺陷。成品各项力学性能均满足技术协议要求,外形尺寸及表面质量满足GB/T 11263—2017标准要求,最终实现了厚规格高强耐候抗震热轧H型钢批量稳定供货。According to the use requirements of prefabricated steel structure residence,the 420 MPa grade high-strength weather-resistant anti-seismic special hot-rolled H beam with thick gauge is developed independently with the peritectic steel design of microalloy composition system of low carbon,copper and nickel as well as near-net-shape casting technology of beam blank and universal rolling technology of section steel,which is mainly applied for stand column of frame structure for steel structure residence.The subcracks and intermediate cracks inside flange of ingot blank as well as surface defects of finished product caused by rolled-in scale during rolling process are eliminated through optimizing the continuous casting and rolling processes.All the mechanical properties of finished product could satisfy the requirements of technical agreement as well as the dimension and surface quality could satisfy the requirements of standard GB/T 11263—2017 so that its stable bulk supply is realized.
