Kakaretso ea Bearing Steel

Ho roala tšepe ho sebelisoa ho etsa libolo, li-rollers le mehele ea ho roala. Ho jara tšepe ho na le boima bo phahameng le bo lekanang, ho hanyetsa ho roala le moeli o phahameng oa rekere. Litlhoko tsa ho lumellana ha lik'hemik'hale tsa lik'hemik'hale, likahare le ho ajoa ha li-inclusions tse se nang tšepe, le ho ajoa ha li-carbides tsa tšepe e nang le tšepe li thata haholo. Ke e 'ngoe ea limaraka tse thata ka ho fetisisa tsa tšepe tlhahisong eohle ea tšepe.

Mekhahlelo ea tšepe ea litšepe tse tloaelehileng ke letoto la tšepe le nang le carbon chromium e phahameng, joalo ka GCr15, Gcr15SiMn, joalo-joalo. Ho feta moo, litšepe tse nang le carburized, joalo ka 20CrNi2Mo, 20Cr2Ni4, joalo-joalo, li ka sebelisoa ho latela maemo a fapaneng a ts'ebetso, litšepe tse sa hloekang, joalo-joalo. litšepe tse kang Cr4Mo4V, Cr15Mo4V2, joalo-joalo.

Thepa ea 'mele ea tšepe e nang le tšepe e kenyelletsa haholo sebopeho sa microstructure, decarburized layer, non-metallic inclusion le macrostructure. Ka kakaretso, lihlahisoa li tsamaisoa ka ho kolobisoa ho chesang le ho taka ka mokhoa o batang. Boemo ba ho pepa bo tla bontšoa konteraka. The macrostructure tšepe e lokela ho ba ntle ho shrinkage cavity, subcutaneous bubble, letheba tšoeu le micro pore. Bohareng ba porosity le porosity e akaretsang e ke ke ea feta sehlopha sa 1.5, 'me karohano e ke ke ea feta sehlopha sa 2. Sebopeho se entsoeng ka tšepe se tla aroloa ka mokhoa o ts'oanang pearlite e ntle. Botebo ba lera la decarburization, li-non-metallic inclusions le ho se lekane ha carbide li tla lumellana le litekanyetso tsa naha tse amehang.
