To the steel used in furnace mantle of blast furnace and complement hot-blast furnace, against the request of bearing thermal fatigue and pressure under the condition .of service, with the compiling of Chinese Standard Technical Specification for Smelting Processing Blast of Iron and Steel Enterprise, the thermal fatigue and strain-aging property of steel Q345-(B,C, GJC) and Q390-(GJC, D)are studied. Furthermore, the contrast analysis on the corresponding property of steel BB502 and BBS03 which originally used in the furnace mantle has been done. The research results 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.
