Analysis of Grinding Process for Composite Roll Surface

复合材料辊是冷轧板材生产线中用于去除带钢表面油液和铁屑的重要部件,使带钢表面光整以提高带钢表面质量。通过ABAQUS软件仿真单颗粒磨粒与复合材料辊的材料无纺布磨削的过程;分析磨削参数和磨削力之间的联系;得出影响复合材料挤油辊表面质量的主要因素为磨削深度和砂轮转速。通过VMC1060B加工中心进行单颗粒磨粒划擦的试验,验证分析结论,证明ABAQUS分析复合材料辊的磨削力是可行的,为复合材料辊的理论和研究提供了数据。

The composite roll is an important component that used in the cold rolling production line to remove the oil and iron scraps on the strip surface.They could improve the surface quality of strip steel.The grinding process of single particle abrasive and non-woven fabric is simulated by large simulation software ABAQUS;analysis the relationship between grinding depth and grinding wheel speed and grinding force;through the analysis of grinding force obtain the influence of grinding factors on the surface quality of material roll.Reducing the grinding depth and increasing the rotational speed of the grinding wheel can improve the quality of the machined surface.Through the VMC1060 B machining center,the single-grain abrasive scratch test was conducted,and the test data was obtained to verify the analysis conclusion.It is proved that it is feasible to analyze the grinding force of the composite roller by ABAQUS.It provides data for theoretical and experimental study of composite rolls.
