摘　　要：介绍了湘钢宽厚板厂试制开发E40级高强度船板的主要技术要求和工艺路线。通过适当的成分设计以及控轧控冷工艺得到了充分细化的针状铁素体和准多边形铁素体及极少量珠光体的复合组织,这种复合组织具有优异的综合力学性能,满足船级社对E40级船板的认证要求。The main specification and process route during production and exploitation of E40 high strength hull structure steel made in Xiangtan Iron ＆ Steel Co., Ltd. were introduced. Based on the design of alloy composition and thermomechanical control process, a mixed microstmcture dominated by acicular ferrite was obtained. The mixed microstmcture has the excellent mechanical properties and can satisfy the demands of E40 hull structure steel with high strength and toughness.
