摘要
研究了厚壁热轧H型钢翼缘宽度方向低温冲击功及显微组织的变化规律。结果表明:从翼缘端部到翼缘根部,铁素体晶粒尺寸逐渐增大,尺寸均匀性变差,低温冲击功大幅下降。
The transformation on low - temperature impact energy and microstructure along the flange of hot - rolled H - beam with thick flange has been studied in this artical. The result indicates that low - temperature impact energy has fallen dramatically when sampling from the edge of flange to the root. Ferrite grain size increase and homogeneity of grain size becaom worse follow the same law.
