金属粉末轧制工艺及装置研究

Research on metal powder rolling and powder application roll

概述金属粉末轧制工艺,分析金属粉末的性能、轧制速度、辊径、辊缝、给料方式等工艺参数对粉末轧制性能的影响。设计一台金属粉末专用轧制试验装置,采用有限元软件对轧制装置进行模态分析和静力分析,计算结果表明,轧制装置工作时的变形趋势小,对轧件精度影响小,装置机械结构满足材料的强度条件和刚度条件要求。

The arts of powder rolling, including the nature of the metal powder, the rolling velocity, the roll＇s diameter, the gap of the rolls, the feeding mode etc. Were analyzed. A metal powder application roll was developed. Finite element software was used to analyze the mode and static force of the equipment. Simulation results show that the equipment can satisfy the requirement of the strength, stiffness and the precision of green rolls.
