煤焦油深加工项目中的核心设备沥青预处理塔设计材料为Incoloy825（复层）+12Cr2Mo1R（基层）复合板。由于材料的特殊性和使用工况的复杂性，要求成形后封头即耐热又耐蚀。封头成形是本设备制造中的难点。采用高温热冲压成形和随后的正火加回火热处理，封头的各项技术指标达到了设计要求。文中介绍了复合板Incoloy825+12Cr2Mo1R材料特性，封头成形工艺，热处理工艺和合格指标。“,”Designed materials for asphalt pretreatment tower which the core equipment in coal tar deep processing project is Incoloy825 clad 12Cr2Mo1R. Due to the particularity of the material and the complexity of the working condition, the vessel heads shall possess heat resistant and corrosion resistant. The head forming is the difficulty in this equipment manufacturing. Uses the high temperature hot stamping and subsequent normalizing and tempering heat treatment, the technical indicators of the head meet the design requirements. This paper introduces the material properties of Incoloy825 clad 12Cr2Mo1R, head forming process, heat treatment process and qualified indicators.
