Cov kabmob yeeb nkab yog ib homseamless steel yeeb nkablos ntawm kub-dov los yog txias-kub (txias kos), siv rau kev tsim cov kabmob zoo tib yam.Sab nraud txoj kab uas hla ntawm cov yeeb nkab feem ntau yog 25-180 hli thiab nrog phab ntsa thickness ntawm 3.5-20 hli.Cov kabmob steel yog siv los ua cov pob, cov menyuam thiab cov kabmob ntawm cov hlau.Bearings ua hauj lwm nyob rau hauv lub siab loj thiab kev sib txhuam, nws yuav tsum tau ib tug siab thiab uniform bearing steel hardness thiab hnav tsis kam, thiab siab elastic txwv.Cov kabmob steel chemical muaj pes tsawg leeg tsis sib xws, cov ntsiab lus tsis yog xim hlau suav nrog thiab kev faib tawm, kev faib tawm ntawm cov carbides thiab lwm yam kev xav tau yog cov kev cai nruj heev ntawm tag nrho cov hlau ntau lawm hauv ib qho ntawm cov qib steel xav tau tshaj plaws.

Cov kabmob steel muaj cov kev xav tau zoo smelting zoo, lub sijhawm no, thiab yuav tsum muaj kev tswj xyuas nruj ntawm cov sulfur, phosphorus, hydrogen cov ntsiab lus, thiab tsis yog xim hlau inclusions thiab carbides ntawm tus naj npawb, qhov loj me thiab kev faib tawm, tsis yog xim hlau inclusions thiab carbides raws li tus naj npawb, qhov loj thiab tis kev pab cuam lub neej ntawm cov kabmob steel zoo cuam tshuam, feem ntau bearing tsis ua hauj lwm yog nyob rau hauv loj carbide inclusions los yog micro-cracks generated nyob ib ncig ntawm lub extension rau.Cov ntsiab lus suav nrog thiab cov ntsiab lus oxygen hauv cov hlau yog ze ze rau cov ntsiab lus ntawm cov pa oxygen ntau dua, ntau qhov kev suav nrog, lub neej luv dua.Thiab carbide suav nrog qhov loj me me, kev faib tawm ntau dua, lub neej ua haujlwm luv dua, thiab lawv qhov loj me, kev faib tawm thiab kev siv cov txheej txheem smelting thiab smelting zoo yog ze ze rau, tam sim no bearing steel ntau lawm thiab cov txheej txheem tseem ceeb yog kev nruam. casting EAF + ESR smelting txheej txheem, nrog rau ib qho me me ntawm lub tshuab nqus tsev induction arc ob lub tshuab nqus tsev lossis + rov qab nqus cov khoom siv thiab lwm yam thev naus laus zis los txhim kho qhov zoo ntawm cov kabmob steel.

Txij li thaum cov kabmob yuav tsum muaj lub neej ntev, siab precision, tsis tshua muaj cua sov, kev kub ceev, siab rigidity, tsis tshua muaj suab nrov, siab hnav tsis kam thiab lwm yam ntxwv, yog li xav tau cov kabmob yeeb nkab yuav tsum muaj: siab hardness, uniform hardness, siab elastic txwv, siab. hu rau qaug zog, yuav tsum toughness, hardenability yuav tsum nyob rau hauv atmospheric corrosion kuj ntawm lubricant.Yuav kom ua tiav cov kev ua tau zoo no, cov tshuaj muaj pes tsawg leeg ntawm steel bearings homogeneity, non-metallic inclusion cov ntsiab lus thiab hom, qhov loj thiab faib ntawm carbides, decarburization xav tau.Zuag qhia tag nrho cov kabmob steel kom zoo, kev ua haujlwm siab thiab ntau hom kev taw qhia.Cov kabmob steel raws li cov yam ntxwv thiab kev siv ib puag ncig tau muab faib ua: siab carbon chromium bearing steel, carburizing bearing steel, kub bearing steel, stainless hlau thiab tshwj xeeb bearing tshwj xeeb bearing khoom.Yuav kom ua tau raws li qhov kub thiab txias, kev kub ceev, siab load, corrosion, tiv thaiv hluav taws xob yuav tsum tau tsim kom muaj kev ua tau zoo tshwj xeeb ntawm cov kabmob tshiab.Txhawm rau txo cov pa oxygen ntawm cov kabmob steel, kev txhim kho ntawm lub tshuab nqus tsev smelting, electroslag remelting, electron beam remelting bearing steel smelting technology.Qhov ntau ntawm cov kabmob steel smelting los ntawm arc melting, los txhim kho rau txhua hom Canadian refining rauv thaum ntxov.
