Pfupiso yeBearing Steel

Simbi yebheya inoshandiswa kugadzira mabhora, maroller nemabheya rings. Simbi yebheya ine kuomarara kwakafanana, kuramba kupfeka uye muganho we elastic wakakwira. Zvinodiwa kuti makemikari aenzane, huwandu uye kupararira kwezvinhu zvisiri zvesimbi, uye kupararira kwema carbides esimbi yebheya zvakanyanyisa. Ndiyo imwe yemhando dzakasimba dzesimbi mukugadzirwa kwesimbi dzese.

Magiredhi esimbi esimbi dzinoshandiswa pamwe chete isimbi dzakatevedzana dzine chromium yakawanda, dzakadai seGCr15, Gcr15SiMn, nezvimwewo. Pamusoro pezvo, simbi dzine carburised bearing, dzakadai se20CrNi2Mo, 20Cr2Ni4, nezvimwewo, dzinogona kushandiswawo zvichienderana nemamiriro akasiyana ekushanda, simbi dzine simbi dzisina ngura, dzakadai se9Cr18, nezvimwewo, uye simbi dzine tembiricha yepamusoro, dzakadai seCr4Mo4V, Cr15Mo4V2, nezvimwewo.

Zvivakwa zvemuviri

Hunhu hwesimbi ine bearing hunonyanya kusanganisira microstructure, decarburised layer, non-metallic inclusion uye macrostructure. Kazhinji, zvigadzirwa zvinounzwa ne hot rolling annealing uye cold drawing annealing. Mamiriro ekutumira anofanira kuratidzwa muchibvumirano. Macrostructure yesimbi inofanira kunge isina shrinkage cavity, subcutaneous bubble, white spot uye micro pore. Central porosity uye general porosity hazvifanirwe kudarika grade 1.5, uye separation haifanirwe kudarika grade 2. Annealed structure yesimbi inofanira kugoverwa zvakaenzana fine-grained pearlite. Kudzika kwe decarburisization layer, non-metallic inclusions uye carbide unevenness zvinofanira kutevedzera mitemo yenyika.
