立辊锥角对H型钢翼缘宽展的影响

Effect of Vertical Rolled Cone Angle on H-beam Flange Lateral Spread

在分析和研究万能法轧制 H型钢的基础上 ,利用有限元的方法建立了 H型钢的轧制模型 ,分析相同的轧制规程 ,不同的立辊锥角时 ,翼缘金属的流动情况 ,结果表明 :轧制 H型钢的过程中 ,翼缘和腹板间的金属有流动现象 ,随着立辊锥角的增加 ,这种流动情况有减弱的趋势。翼缘的宽展量随立辊锥角的增加而减小。分析试验室轧制铅试件的测试数据可知 ,模拟值与实测值吻合良好。对 H型钢的轧制有参考意义。

On the base of studying and analysing universal method rolling H-beam, rolling model of H-beam was established using finite-element method and the flange metal's flowing was analyzed under same rolling regulations and different vertical roller cone angle. The results indicate that the flange and web's metals can flow. This tend is weaken with increase of vertical roller cone angle. Flange lateral spread minimizes with increment of vertical roller cone angle.By analysing the datum of test and measurement of rolling lead samples in laboratory, the calculation result is very inosculated with the measured value, which have provided the references for the rolling of H-beam.
