工作辊局部缺陷定量化磨削方法

针对宝钢集团新疆八钢公司热轧薄板厂缺陷辊磨削耗时、砂轮消耗量大、磨削效率低、辊耗高的问题，提出一种简单且对裂纹等缺陷定量准确的操作方法，可对缺陷大小、深浅进行客观、准确的判断和定量化，从而可以有效控制缺陷辊的磨削量，保证缺陷辊的磨削合格率，节约砂轮消耗，降低辊耗，提高磨削效率。

Quantitative Grinding Method for Work Roll with Partial Defects

In view of the problems of low efficiency and long time grinding, large consumption of roll and abrasive wheel at defect roll grinding, a useful method was put forward, which can accurately judge the size and depth of defect of roll, and the grinding process can be controlled well.
