15Cr1Mo1V高压锅炉管的开发及其高温组织稳定性研究
|
摘要
15Cr1Mo1V是俄罗斯标准的高压锅炉管用钢牌号,该钢种具有较高的热强性和高温抗氧化性,在俄罗斯以及我国的电厂均有应用。介绍15Cr1Mo1V钢管的生产工艺,检验成品钢管的室温力学性能、四象限硬度性能及金相组织,分析其组织稳定性。试验结果表明:15Cr1Mo1V钢管的成分设计和热处理工艺合理,产品性能优良,全部检验性能符合ТУ14-3P-55—2001标准要求;成品15Cr1Mo1V钢管组织为F+B,组织均匀,无黄块状组织;该产品在高温下的组织稳定性好。
The 15 Cr1 Mo1 V steel specified as a steel type in relevant Russian standard for hi-pressure boiler pipe.This steel is in possession of rather high heat resistance and high-temperature oxidation resistance,having been widely used in power plants both in China and Russia. Elaborated here in the paper are the main aspects of the 15 Cr1 Mo1 V steel tube,including the manufacturing process,inspection and testing of the ambient mechanical properties,the 4-quarant hardness and the metallographic structure. Moreover the structural consistency of the tube is analyzed. The test results show that both the chemical composition design of and the heat treatment process for the tube are proper,and the product performances are excellent,all the properties as tested are up to the requirements as specified in Specification ТУ 14-3 P-55—2001; micro-structure of the finished tube is F +B, being homogeneous, and free of any yellow block structure;and at high temperature the tube presents satisfactory structural stability.
