上海工业大学最近研制出电脑剩磁硬度分选仪,它具有较好的实用价值。检测零件表面硬度是了解热处理质量、保证产品性能的重要一环。目前多用破坏性方法进行检测,这种手工操作,既费力、费料,且精度也难于保证。该新型电脑硬度分选仪用无损检测、分选检测,重复性低,精度高。 Shanghai University of Technology recently developed computer residual magnetic hardness sorting device, it has good practical value. Detecting the surface hardness of parts is to understand the quality of heat treatment, an important part of ensuring product performance. At present, more methods are used to detect destructive, this manual operation, both laborious, costly, and accuracy is difficult to guarantee. The new computer hardness sorting with nondestructive testing, sorting testing, low repeatability, high precision.
