摘要
针对Q420qE桥梁用钢板,研究了不同温度下火焰矫正对其微观组织及力学性能的影响.结果表明矫正温度在800℃以下时,钢的力学性能和微观组织均无明显变化;当矫正温度大于900℃时,钢的微观组织有长大的倾向.
Abstract
In this paper,the influence of flame correction on the microstructure and mechanical properties of Q420qE bridge steel plate at different temperatures is studied.The results show that when the correction temperature is below 800 ℃,the mechanical properties and microstructure have no significant changes.When the correction temperature is greater than 900 ℃,the microstructure tends to grow.
