Dab tsi yog qhov txhais ntawm bearing steel?
Cov kabmob hlau tseem hu ua high-carbon chromium steel, cov ntsiab lus carbon ntawm Wc yog li 1%, cov ntsiab lus chromium ntawm Wcr yog 0.5%-1.65%. Cov kabmob hlau tau muab faib ua 6 pawg: high-carbon chromium bearing steel, non-chromium bearing steel, carburized bearing steel, stainless bearing steel, nruab nrab thiab kub bearing steel thiab anti-magnetic bearing steel.
High carbon chromium bearing steel GCr15 yog lub ntiaj teb loj tshaj plaws ntawm cov kabmob steel, carbon Wc yog li 1%, chromium cov ntsiab lus Wcr yog li 1.5%, txij xyoo 1901 mus txog rau hnub yug ntau tshaj 100 xyoo, cov ntsiab lus tseem ceeb tsis hloov pauv, nrog rau kev kawm ntawm kev tshawb fawb thiab thev naus laus zis, kev tshawb fawb ua haujlwm txuas ntxiv, cov khoom lag luam zoo txuas ntxiv txhim kho, Nws suav rau ntau dua 80% ntawm lub ntiaj teb tag nrho cov kabmob steel ntau lawm. Yog li ntawd yog tias tsis muaj cov lus piav qhia tshwj xeeb ntawm cov kabmob hlau, nws hais txog GCr15.
Bearing steel yog cov hlau siv los ua cov pob, cov menyuam thiab cov kabmob rings. Cov kabmob steel muaj qhov siab thiab tsis sib xws hardness thiab hnav tsis kam, nrog rau kev txwv siab elastic. Cov kev cai rau kev sib xyaw ntawm cov tshuaj muaj pes tsawg leeg ntawm cov kabmob steel, cov ntsiab lus thiab kev faib tawm ntawm cov khoom tsis yog xim hlau, thiab kev faib tawm ntawm cov carbides yog nruj heev, thiab nws yog ib qho ntawm cov qib steel nruj tshaj plaws nyob rau hauv tag nrho cov hlau ntau lawm.

Classification ntawm bearing steel
Cov kabmob hlau tau muab faib ua cov pa roj carbon chromium bearing steel, carburized bearing steel, stainless hlau bearing thiab lwm yam. Carburized bearing steel hardenability thiab toughness yog zoo dua li carbon bearing steel, tsis yooj yim rau overheat, thiab quenching deformation yog me me, hnav tsis kam. Stainless hlau bearing muaj siab corrosion kuj thiab acid overcorrosion kuj nyob rau hauv ib co xov xwm, uas yog 2 zaug siab dua 18-8 stainless hlau.

Qhov zoo ntawm bearing steel
Bearing steel qib thiab nws daim ntawv thov
GCr15 bearing hlau
GCr15 yog lub siab carbon chromium bearing steel, dav siv nyob rau hauv bearings, linear bearings thiab kis iav thiab lwm yam teb. Cov hlau muaj kev hnav zoo heev thiab hardness, thiab haum rau kev kub ceev, siab load thiab kub kub ua haujlwm. Tib lub sijhawm, GCr15 kuj muaj qee yam hardenability, rigidity thiab qaug zog ua haujlwm.
G20CrNiMo cov kabmob steel
G20CrNiMo yog ib qho nruab nrab carbon chromium-nickel bearing steel yam ntxwv los ntawm lub zog siab, toughness thiab qaug zog tsis kam. Haum rau cov kabmob thiab cycloidal iav rau cov khoom loj thiab hnyav.
GCr9SiMn bearing hlau
GCr9SiMn yog ib hom manganese-silicon bearing steel, uas muaj kev ua haujlwm zoo ntawm kev poob siab, thiab siv dav hauv cov kabmob thiab cov kab bearings nrog kev sib hloov ceev hauv lub sijhawm luv luv. Cov hlau muaj lub zog siab, nruj thiab qaug zog, thiab tsim nyog rau kev kub ceev, siab-load thiab nruab nrab-siab kub ib puag ncig.

G20Cr2Ni4A cov kabmob steel
G20Cr2Ni4A yog ib qho nruab nrab carbon steel haum rau kev kub ceev thiab lub teeb load, nrog siab hardness thiab lub zog, kuj yooj yim rau txheej txheem thiab kev kho cua sov. Haum rau cov kabmob me me, cov iav loj thiab cov kabmob uas tsis tshua muaj siab nrog ntau hom thiab cov kev xav tau precision.
GCr15SiMn cov kabmob steel
GCr15SiMn yog ib hom kev ua haujlwm siab, siab hnav tsis kam ntawm chromium silicon manganese bearing steel, nrog kev qaug zog zoo, feem ntau yog siv hauv cov kabmob hnyav thiab ceev ceev thiab cycloidal iav, tsav ncej thiab lwm yam.
GCr18MoS2 tsis tshua muaj suab nrov bearing steel
GCr18MoS2 yog lub suab nrov qis uas muaj kev tiv thaiv zoo corrosion, siab zog thiab siab hardness, haum rau bearing qhov chaw nyob rau hauv high-speed thiab high-load ua hauj lwm ib puag ncig.
GCr15VA tsis tshua muaj kub bearing steel
GCr15VA yog ib yam ntawm Cr-Mo bearing steel nrog zoo kub tsis tshua muaj toughness thiab hnav tsis kam, uas yog haum rau tshwj xeeb bearings thiab kis iav qhov chaw nyob rau hauv qis kub ib puag ncig.

Kub hlau npaj
Kev tsim cov kabmob steel feem ntau yog siv ob txoj hauv kev ntawm lub tshuab hluav taws xob thiab hloov pauv smelting, txawm tias siv txoj kev twg, cov hlau kub yuav tsum tau npaj raws li qhov yuav tsum tau ua, suav nrog cov hlau kub kub, cov ntsiab lus carbon, cov ntsiab lus sulfur, suav nrog, thiab lwm yam. yuav tsum tau kuaj thiab tshuaj xyuas ua ntej lub qhov cub kom ntseeg tau tias qhov zoo ntawm cov hlau kub ua tau raws li qhov yuav tsum tau ua.

Kev npaj cov alloys ntxiv
Feem ntau ntxiv cov alloys ntxiv nrog rau silicon, manganese, chromium, npib tsib xee, molybdenum, potassium, calcium, thiab lwm yam, yuav tsum tau suav cov feem ntawm cov khoom xyaw alloy ua ntej, thiab tom qab ntawd ntxiv rau tus nqi raws li qhov yuav tsum tau ua.

smelting
Ntxiv cov nqi --- Melting --Tempering
Ntxiv cov nqi: Maj mam hliv cov hlau kub npaj thiab cov hlau ntxiv rau hauv lub cub tawg, ua tib zoo saib xyuas qhov kev sib txuas ntxiv, zam qhov kub ntawm qhov kub los yog qis, thaum ntxiv ntau dhau yuav ua rau tus nqi txaws lossis dhau. Tus nqi ntxiv rau lub cub tawg yog yaj kom ncav cuag qhov kub thiab txias thiab lub xeev ntawm cov tshuaj tiv thaiv los xyuas kom meej qhov zoo ntawm cov hlau. Los ntawm kev kho cov ntsiab lus ntawm carbon thiab sulfur nyob rau hauv tus nqi, ntxiv txiv qaub, titanium nitride, acicular boron nitride thiab lwm yam tshuaj, kho cov nplej, theem qauv thiab tis nyob rau hauv cov hlau tuaj yeem txhim kho cov kev ua tau zoo ntawm cov hlau.

Casting thiab forging
Casting: Cov khoom tsim nyog molten hlau yog tshuaj ntsuam xyuas, purified, nchuav rau hauv pwm, txias thiab solidified rau hauv cov duab uas xav tau ntawm lub billet. Forging: Lub billet yog rhuab mus rau lub microstructure ntawm lub ncua sij hawm, thiab tom qab ntawd los ntawm forging ua los hloov cov duab, loj thiab txhua yam khoom ntawm lub billet, zoo dua casting steel kev ua tau zoo, feem ntau siv nyob rau hauv zus tau tej cov bearings loj.
5
Kev kho cua sov
quenching: Cov hlau qhov chaw yog rhuab mus rau qhov sib thooj quenching kub, thiab cov hlau qhov chaw yog txias sai sai tom qab ib lub sij hawm ntawm lub sij hawm, kom cov hlau qhov chaw tau siab hardness thiab tej yam brittleness. Tempering: Tom qab quenching, steel qhov chaw yog rhuab mus rau ib tug qis kub, thiab cov hlau qhov chaw yog txias maj mam tom qab ib tug sib xws cua sov rau ib lub sij hawm, kom cov hlau qhov chaw tau ib tug tej yam toughness. Yog tias tsim nyog, nws tuaj yeem quenched thiab tempered ob peb zaug kom tau txais qhov kev xav tau.
