Zvigadzirwa Zvedu
Mhete Yokukuya yeGayo
Zvakanakira zvehunyanzvi
Kusapera kwezvishongedzo zvemugayo kwakakosha. Kazhinji, vanhu vazhinji vanofunga kuti kana chigadzirwa chakaoma, chinowanzo shandiswa, saka, mafekitori mazhinji anozivisa kuti zvinhu zvavo zvine chromium, huwandu hwacho hunosvika 30%, uye kuomarara kweHRC kunosvika 63-65. Zvisinei, kana kupararira kwacho kwakapararira, mukana wekugadzira maburi madiki nemakatsemuka panosangana matrix nemacarbides unowedzera, uye mukana wekutyoka uchavawo wakakura. Uye kana chinhu chakaoma, zvinova zvakaoma kucheka. Naizvozvo, kugadzira mhete yekukuya isingapfeki uye inogara kwenguva refu hakusi nyore. Mhete yekukuya inonyanya kushandisa mhando mbiri dzezvinhu zvinotevera.
65Mn (65 manganese): chinhu ichi chinogona kuvandudza kusimba kweringi yekukuya. Chine hunhu hwekuomarara kwakanyanya, kuramba kupfeka zvakanaka uye kuramba simba remagineti zvakanaka, chinonyanya kushandiswa mumunda wekugadzirisa hupfu uko chigadzirwa chinofanira kubvisa simbi. Kuramba kupfeka uye kusimba kunogona kuvandudzwa zvakanyanya nekugadzirisa uye kudzikamisa kupisa.
Mn13 (13 manganese): kusimba kwe grinding ring casting neMn13 kwavandudzika zvichienzaniswa ne65Mn. Ma castings echigadzirwa ichi anobatwa nekusimba kwemvura mushure mekudururwa, ma castings ane simba guru rekudhonza, kuomarara, plasticity uye zvinhu zvisina simba remagineti mushure mekuomarara kwemvura, zvichiita kuti grinding ring igare kwenguva refu. Kana ikakuvadzwa zvakanyanya uye kudzvanywa kwakasimba panguva yekumhanya, pamusoro payo pachaomarara uye pachagadzirwa martensite, nokudaro ichigadzira jira repamusoro rinodzivirira kupera, jira remukati rinochengetedza kusimba kwakanaka, kunyangwe rakapfekwa kusvika panzvimbo yakatetepa, grinding roller inogona kuramba yakatakura zvinhu zvakawanda.
