摘　　要：济钢在特厚容器钢板开发中应用叠轧工艺,成功试制出160 mm厚度Q345R压力容器钢板。组织分析和力学性能检验证明试制钢板的复合界面接触良好,复合界面与基体的组织、性能一致,具有良好的抗层状撕裂和剪切能力,各项性能优异。Jigang applies pack rolling process in development of extra heavy steel plate for pressure vessel,trial-produces 160 mm thick Q345 R steel plate successfully. The microstructure analysis and mechanical properties test prove that the bonding interface of clad steel plate has sound contact with consistent microstructure and properties in bonding interface and base metal. The cladding interface attains good lamellar tearing and shearing resistance.
