【摘要】 本文针对高炉及热风炉炉壳用钢在服役条件下所承受热疲劳和压力的要求,结合国标《钢铁企业冶炼工艺炉技术规范》的编制要求,对Q345(B,C,GJC)、Q390(GJC,D)钢的热疲劳性能和应变时效性能进行了研究,并和原使用钢种BB502、BB503钢的相应性能进行了对比分析,本文的研究成果不仅为规范的编制提供了大量可靠的试验数据,也为高炉及其配套热风炉炉壳用钢种的拓展进行了可行性分析。更多还原

【Abstract】 To the steel used in furnace mantle of blast furnace and complement hot-blast furnace, against the request of bearing fatigue and pressure under the condition of service, with the establishing request of Chinese Standard <Technical Specification for smelting Processing Blast of Iron and Steel Enterprise>, we did some research on the thermal fatigue and strain-aging property of steel Q345(B,C,GJC) and Q390(GJC,D) in this article. Furthermore, we also did some contrast analysis on the corresponding property of steel BB502 and BB503 which originally used in the furnace mantle. The research production of this article supply not only large reliable test data for the establishing of Chinese Standard, but also feasibility analysis for development research of steel used in furnace mantle of blast furnace and complement.更多还原
