本文研究了25SiMnMoV钢在不同奥氏体优化温度、加热速度及冷却速度下组织变化规律.并分析了D级矿用圆环链焊接接头组织.可为矿用圆环链焊接、热处理生产提供组织转变理论依据。
In this paper, the microstructure variation of 25SiMnMoV steel at different austenite temperature, heating rate and cooling rate was studied, and the structure of D-level mine ring chain welded joint was analyzed. It can provide the organization for the production of circular chain welding and heat treatment Change the theoretical basis.
