摘要

摘要: 由于锆管磨削的特殊理化性能,运用传统磨削工艺,导致其磨削热大,工件表面易灼伤,而砂带由于具有磨削温度低,工件表面不易出现烧伤等特点,而有"冷态磨削"之称。采用3种不同磨料砂带对锆管进行工艺试验,对磨削后工件的标准切除率和表面粗糙度及砂带磨损表面形貌进行了观测,得出适合磨削锆管的最优砂带和次优砂带。利用ImageProPlus专业图形处理软件处理计算由相机采集的图片,很好的对砂带的堵塞情况进行了分析。讨论了砂带线速度对标准材料切除率的影响,经试验砂带线速度为12 m/s,材料切出率达到最大值,并且砂带磨损较合理。

Abstract: Because of special rationalized performances of Zircaloy grinding,using conventional grinding technology will bring about the grinding hot and the workpiece to surface burning,but the abrasive belt has mush characteristics,for example,the grinding temperature is much low and the workpiece of surface is not easy to be burned,so it is called as"cold grinding".This article adopts three different abrasive belts doing experimental process about zirconium tube,observing the workpiece of the standard of material removal rate,the surface roughness and the surface of the worn belt after grinding,and finding out which is most suitable for the abrasive belt grinding of Zircaloy tube.The professional graphic processing software Image-Pro Plus is used to process and calculate the pictures that are collected by the camera for analyzing the situation of belt plug.Also,the influence of belt speed on the standard material removal rate is investigated,when the belt speed is 12 m/s with the experiment,the material removing efficiency achieves maximum value,and the belt wear is more reasonable.
