Mhedziso yeBearing Steel

Kutakura simbi inoshandiswa kugadzira mabhora, rollers uye zvindori zvinotakura.Kutakura simbi kune yakakwirira uye yunifomu kuoma, kupfeka kuramba uye yakakwirira elastic muganho.Izvo zvinodiwa zvekufananidzwa kwemakemikari ekugadzirwa, zvinyorwa uye kugoverwa kwezvisina-metallic inclusions, uye kugoverwa kwecarbides yekutakura simbi yakaoma zvikuru.Ndiyo imwe yeakanyanya kuomesesa simbi mamakisi mune zvese kugadzirwa kwesimbi.

Magiredhi esimbi emasimbi akajairika akakwira kabhoni chromium inotakura simbi dzakatevedzana, dzakadai seGCr15, Gcr15SiMn, nezvimwewo. Pamusoro pezvo, masimbi ane carburized, akadai 20CrNi2Mo, 20Cr2Ni4, nezvimwewo, anogonawo kushandiswa zvinoenderana nemamiriro ekushanda akasiyana, asina tsvina. simbi inotakura simbi, yakadai se9Cr18, nezvimwewo, uye yakakwirira-yekushisa inotakura simbi, dzakadai seCr4Mo4V, Cr15Mo4V2, nezvimwewo.

Pfuma yenyama

Izvo zvemuviri zvimiro zvekubereka simbi zvinonyanya kusanganisira microstructure, decarburized layer, isiri-metallic inclusion uye macrostructure.Kazhinji, zvigadzirwa zvinounzwa nekupisa kutenderedza annealing uye kutonhora kudhirowa annealing.Mamiriro ekutumira acharatidzwa muchibvumirano.Iyo macrostructure yesimbi inofanira kunge isina shrinkage cavity, subcutaneous bubble, white spot uye micro pore.Iyo yepakati porosity uye general porosity haingapfuuri giredhi 1.5, uye kupatsanurwa hakuzopfuure giredhi 2. Iyo annealed chimiro chesimbi ichagoverwa zvakafanana fine-grained pearlite.Kudzika kwe decarburization layer, non-metallic inclusions uye carbide kusaenzana kunoenderana nemitemo yenyika.
