Kana tichiyedza kuomarara kwekabhoni simbi yakatenderedza mabhawa nekuomarara kwakaderera, isu tinofanirwa kusarudza yekuomarara tester zvine musoro kuti tive nechokwadi chekuti mhedzisiro yebvunzo ndeyechokwadi uye inoshanda. Tinogona kufunga kushandisa HRB chiyero che Rockwell kuomarara tester.
Chikero cheHRB cheRockwell hardness tester chinoshandisa indenter yesimbi ine dhayamita ye1.588mm uye simba rekuyedza rinoenderana re100KG. Iyo kuyerwa kwechiyero cheHRB chikero chakaiswa pa20-100HRB, iyo inokodzera kuongororwa kuomarara kweakawanda kabhoni simbi yakatenderedza bar zvinhu zvine kuderera kuomarara.
1.Kana iyo carbon steel round bar yakadzimwa uye ine kuoma kwepamusoro kwepamusoro peHRC40 - HRC65, unofanira kusarudza Rockwell hardness tester. Rockwell hardness tester iri nyore uye inokurumidza kushanda, uye inogona kuverenga zvakananga kukosha kwekuoma, iyo yakakodzera kuyera yakakwirira kuomarara zvinhu.
2.Kune mamwe carbon steel round bars akabatwa ne carburizing, nitriding, etc., kuoma kwepamusoro kwakakwirira uye kuoma kwepakati kwakaderera. Pazvinenge zvakakodzera kuyera kuoma kwepamusoro, Vickers hardness tester kana microhardness tester inogona kusarudzwa. Iyo indentation yeVickers kuomarara bvunzo yakaenzana, uye kukosha kwekuoma kunoverengerwa nekuyera kureba kwediagonal. Iko kuyerwa kwechiyero kwakakwira uye kunogona kunyatso ratidza kuoma kushanduka pane zvinhu.
3.Kuwedzera kune HRB chiyero cheRockwell hardness tester, Brinell hardness tester inogonawo kushandiswa kuedza yakaderera-yakaoma carbon steel round bar zvinhu. Paunenge uchiyedza kabhoni simbi yakatenderedza mabara, indenter yayo inosiya nzvimbo yakakura yekumisikidza pamusoro pechinhu, icho chinogona kunyatso ratidza uye nekunyatso kuratidza avhareji kuoma kwezvinhu. Panguva yekushanda kweiyo hardness tester, Brinell hardness tester haina kukurumidza uye nyore se Rockwell hardness tester. Brinell hardness tester ndicho chikero cheHBW, uye ma indenters akasiyana anofananidza simba rekuyedza. Kune kabhoni simbi yakatenderera mabara ane kazhinji kuomarara kwakaderera, seaya ari munzvimbo yakavharwa, kuomarara kunowanzo kutenderedza HB100 - HB200, uye Brinell kuomarara tester inogona kusarudzwa.
4.Kune kabhoni simbi yakatenderedza mbariro ine dhayamita yakakura uye chimiro chenguva dzose, akasiyana-siyana ekuomarara testers anowanzo kushanda. Zvisinei, kana dhayamita yebhawa yakatenderera iri diki, senge isingasviki 10mm, Brinell hardness tester inogona kukanganisa kuyerwa kwechiyero nekuda kweiyo indentation yakakura. Panguva ino, Rockwell hardness tester kana Vickers hardness tester inogona kusarudzwa. Saizi yavo yeindenter idiki uye inogona kunyatso kuyera kuomarara kwemasample madiki-saizi.
5.Nekuda kwemaitiro asina kuumbwa kabhoni simbi yakatenderedza mbariro iyo yakaoma kuisa pabhenji rebasa rekare rekuomarara tester yekuyera, inotakurika yakaoma tester, yakadai seLeeb hardness tester, inogona kusarudzwa. Inoshandisa mudziyo wekuita kuti utumire muviri unobata pamusoro pechinhu chiri kuyerwa, uye inoverengera kukosha kwekuomarara zvichienderana nekumhanya kunodzokororwa nemuviri. Zviri nyore kushanda uye zvinogona kuita pa-saiti kuyerwa pane workpiece yemhando dzakasiyana uye saizi.
