钢件热处理质量无损测试仪的基本测量原理是直流矫顽力法。应用于机械零件的淬硬层深度,表面和心部硬度,预先热处理状态,碳素钢的含碳量和鉴别异材等的无损检测。特别适合大批量、工艺稳定的零件检验。测量迅速、操作简便。本文还简单地介绍了仪器的结构和使用方法。 Heat treatment of steel quality non-destructive tester basic measurement principle is the DC coercivity method. Applied to mechanical parts hardened layer depth, surface and core hardness, pre-heat treatment state, the carbon content of carbon steel and identification of non-destructive testing of different materials. Particularly suitable for high-volume, process-stable parts inspection. Rapid measurement, easy to operate. This article also briefly introduces the structure and use of the instrument.
