直线导轨防护罩的硬度检验方式您了解吗?

来源:http://www.jngongrun.com/ 日期:2019-12-31 发布人:admin

  直线导轨防护罩的性能直接影响其加工质量,其中硬度值是决定铸件加工质量的重要指标。

  The performance of linear guide protective cover directly affects its processing quality, and the hardness value is an important index to determine the processing quality of castings.
  布氏硬度:主要用于测定铸造、锻造、有色金属零件、热轧钢坯的硬度和退火,测量范围≯HB450。
  Brinell hardness: it is mainly used to determine the hardness and annealing of casting, forging, non-ferrous metal parts and hot-rolled steel billets, and the measurement range is no more than hb450.
  2. 洛氏硬度:HRA主要用于高硬度试件,用于测定材料和表面硬度高于HRC67的材料,如硬质合金、氮化钢等。测定范围为HRA>70。HRC主要用于钢件(如碳钢、工具钢、合金钢等)淬火、回火后的硬度测定。测量范围为HRC20~67。

  2. Rockwell hardness: HRA is mainly used for high hardness test pieces, for measuring materials and materials with surface hardness higher than hrc67, such as cemented carbide, nitriding steel, etc. The determination range is HRA > 70. HRC is mainly used for hardness measurement of steel parts (such as carbon steel, tool steel, alloy steel, etc.) after quenching and tempering. The measurement range is hrc20 ~ 67.
  3.维氏硬度:用于测定薄壁件和导轨护罩的硬度,也可用于测定渗碳、氰化、氮化等表面硬化机床铸件的硬度。
  3. Vickers hardness: it is used to measure the hardness of thin-walled parts and guide rails, and also used to measure the hardness of surface hardening machine castings such as carburizing, cyaniding, nitriding, etc.
