在使用 雷蒙磨时，长时间未添加润滑剂或润滑油，但添加的润滑剂或润滑油选择错误。如果填充不到位，机器将会损坏，轴承变形，安装不到位。磨辊向外摆动，压迫磨环，导致刀片铲起磨辊与磨环之间的物料。雷蒙磨磨环磨损，钢锭固化冷却，体积收缩，最终固化的液态金属部件无法添加，将形成孔状缺陷。
     
大的集中孔称为收缩腔。空间称为骨质疏松症，是小而分散的。其内表面粗糙，周围有许多杂质和微孔。由于热胀冷缩的规律，收缩是不可避免的，尺寸和位置，或者当其延伸到锭时，它就是体的缺陷。为了提前防止这些缺陷的发生，我们可以从源头尽量减少它们。
     
雷蒙磨's grinding roller grinding ring fails to escape the gas during metal solidification process. The metal is formed in a small hole, the ultrasonic wave has a high reflectivity, and because of its substantially spherical or elliptical shape, the porosity of the steel ingot is forged. Or after rolling, it is flattened into area type defects and found to benefit from ultrasonic testing. Ultrafine grinding of the grinding ring during the reaction of the grinding ring, or the addition of some components of the metal parts of the material to form incompletely molten metal inclusions, such as high density, high melting point, such as tungsten, molybdenum.
