摘要
通过600℃高温持久试验和透射电镜研究了(％):0～0.49W、0.01～0.13Mo、0.01～0.47Nb对(％) 0.03C、0.99～1.01Mn、0.005～0.028Ti耐火建筑钢耐火性能的影响。试验结果表明,复合添加0.05％～0.13％Mo- 0.47％Nb的耐火钢在600℃230 MPa载荷保持5 h不发生断裂,能满足耐火钢的设计要求,单独添Mo、W的耐火钢的耐火性能不能满足设计要求。
The effect of 0 -0.49W, 0. 01 -0. 13Mo, 0.01 -0. 47Nb on fire resistant steel 0.03C,0. 99-1.01Mn, 0. 005 - 0. 028Ti for building has studied by 600 ℃ high temperature stress-rupture test and TEM. Test results showed that there were no-rupture for the fire-resistant steels containing compound addition 0.05% - 0. 13% Mo-0.47% Nb with stress 230 MPa at 600℃ for 5 h which meet the design requirement for fire-resistant steel, and the fire-resistant properties of fireresistant steel singly added Mo, W could not satisfy the design requirement.
