compound roll是什么意思

用法例句

In order to make tungsten carbide/steel composite roll rings of low cost,based on the relationship between required bonding strength and rolling torque and the bonding strength of different glues,the tungsten carbide/steel composite roll rings were developed by use of chemical bonding,and the composite rolls were tested on the Pomini mill.

为了制造低成本的硬质合金/钢复合辊环,根据对复合强度与轧制扭矩关系的计算及对不同胶结剂复合强度研究,用化学胶结工艺制造了硬质合金复合辊环,与辊轴装配成复合轧辊,在Pomini棒材轧机上进行了轧制性能试验,与冶金工艺制造的复合辊环进行了对比。
