Isishwankathelo sokuBearing Steel

Ukuthwala intsimbi kusetyenziselwa ukwenza iibhola, ii-roller kunye namakhonkco okuthwala.Ukuthwala intsimbi kunobunzima obuphezulu kunye nobukhulu obufanayo, ukuxhathisa ukugqoka kunye nomda ophezulu we-elastic.Iimfuno zokufana kokwakheka kweekhemikhali, umxholo kunye nokuhanjiswa kwe-non-metallic inclusions, kunye nokuhanjiswa kwee-carbides zentsimbi ezithwele zingqongqo kakhulu.Ngomnye wemigangatho yentsimbi engqongqo kakhulu kuyo yonke imveliso yentsimbi.

Amabakala ensimbi yeentsimbi eziqhelekileyo ezixhaphakileyo ziphezulu ze-carbon chromium ezithwele uchungechunge lwensimbi, njenge-GCr15, Gcr15SiMn, njl. Ukongeza, iintsimbi ezithwala i-carburized, ezifana ne-20CrNi2Mo, 20Cr2Ni4, njl., zingasetyenziselwa ngokweemeko zokusebenza ezahlukeneyo, ezingenasici. iintsimbi zentsimbi, ezifana ne-9Cr18, njl., kunye ne-high-temperature bear steels, njenge-Cr4Mo4V, i-Cr15Mo4V2, njl.

Izinto eziphathekayo

Iimpawu ezibonakalayo zentsimbi yokuthwala ikakhulu ziquka i-microstructure, i-decarburized layer, inclusion non-metallic kunye ne-macrostructure.Ngokubanzi, iimveliso zihanjiswa nge-annealing eshushu yokuqengqeleka kunye ne-annealing ebandayo yokuzoba.Ubume bokuhanjiswa buya kuboniswa kwikhontrakthi.I-macrostructure yentsimbi kufuneka ingabikho kwi-shrinkage cavity, i-bubble subcutaneous, indawo emhlophe kunye ne-micro pore.I-porosity ephakathi kunye ne-porosity jikelele ayiyi kudlula i-grade 1.5, kwaye ukuhlukana akuyi kudlula i-grade 2. Isakhiwo se-annealed yensimbi siya kuhanjiswa ngokufanayo i-pearlite ecocekileyo.Ubunzulu bomaleko we-decarburization, inclusions non-metallic kunye nokungalingani kwe-carbide kuya kuhambelana nemigangatho yelizwe efanelekileyo.
