Chidule cha Bearing Steel

Kunyamula zitsulo kumagwiritsidwa ntchito popanga mipira, odzigudubuza ndi mphete zoberekera. Kunyamula zitsulo kumakhala ndi kuuma kwakukulu ndi yunifolomu, kuvala kukana ndi malire apamwamba zotanuka. Zofunikira pakufanana kwa mankhwala, zomwe zili ndi kugawa kwazinthu zopanda zitsulo, komanso kugawa kwa carbides zitsulo zokhala ndi zitsulo zimakhala zovuta kwambiri. Ndi imodzi mwamagiredi olimba kwambiri pakupanga zitsulo zonse.

Zitsulo zazitsulo zazitsulo zomwe zimagwiritsidwa ntchito ndi carbon chromium yokhala ndi zitsulo zambiri, monga GCr15, Gcr15SiMn, etc. zitsulo zokhala ndi zitsulo, monga 9Cr18, etc., ndi zitsulo zotentha kwambiri, monga Cr4Mo4V, Cr15Mo4V2, etc.

Katundu wakuthupi

Zomwe zimapangidwira zitsulo zokhala ndi zitsulo makamaka zimaphatikizapo microstructure, decarburized layer, non-metal inclusion and macrostructure. Nthawi zambiri, zinthuzo zimaperekedwa ndi kugudubuzika kotentha komanso kuzizira kojambula. Mkhalidwe wobweretsera udzawonetsedwa mu mgwirizano. Ma macrostructure achitsulo ayenera kukhala opanda shrinkage patsekeke, subcutaneous kuwira, banga loyera ndi yaying'ono pore. Pakati pa porosity ndi general porosity sichidzapitirira kalasi ya 1.5, ndipo tsankho silingathe kupitirira kalasi ya 2. Mapangidwe a annealed a zitsulo adzagawidwa mofanana bwino-grained pearlite. Kuzama kwa decarburization layer, non-metal inclusions ndi carbide kusagwirizana kumagwirizana ndi zofunikira za dziko.
