Cov kabmob steel feem ntau yog siv los tsim cov khoom dov thiab cov nplhaib ntawm cov kabmob dov.Vim tias cov kabmob yuav tsum muaj lub neej ntev, siab precision, tsis tshua muaj cua sov, kev kub ceev, siab nruj, tsis tshua muaj suab nrov, siab hnav tsis kam, thiab lwm yam., cov kabmob steel yuav tsum muaj: siab hardness, uniform hardness, siab elastic txwv, siab tiv taus qaug zog. Lub zog, tsim nyog toughness, tej yam hardenability, corrosion kuj nyob rau hauv lubricants nyob rau hauv cov huab cua.Txhawm rau ua kom tau raws li qhov xav tau ntawm kev ua haujlwm saum toj no, cov kev xav tau rau kev sib koom ua ke ntawm cov tshuaj muaj pes tsawg leeg ntawm cov kabmob steel, cov ntsiab lus thiab hom tsis yog xim hlau suav nrog, qhov loj thiab kev faib tawm ntawm carbides, thiab decarburization yog nruj.Cov kabmob hlau feem ntau yog tsim los ntawm kev ua haujlwm siab, kev ua haujlwm siab thiab ntau yam.Cov kabmob hlau tau muab faib ua cov pa roj carbon siab chromium bearing steel, carburizing bearing steel, kub bearing steel, stainless bearing steel thiab tshwj xeeb tshwj xeeb bearing cov ntaub ntawv raws li cov yam ntxwv thiab daim ntawv thov ib puag ncig.Txhawm rau ua kom tau raws li qhov yuav tsum tau muaj ntawm qhov kub thiab txias, kev kub ceev, siab load, corrosion kuj thiab hluav taws xob tsis kam, yuav tsum tau tsim cov txheej txheem tshiab ntawm cov kabmob steel nrog cov khoom tshwj xeeb.Txhawm rau txo cov pa oxygen cov ntsiab lus ntawm cov kabmob steel, smelting thev naus laus zis rau cov kabmob steel xws li lub tshuab nqus tsev, electroslag remelting, thiab electron beam remelting tau tsim.Lub smelting ntawm ntau qhov bearing steel tau tsim los ntawm hluav taws xob arc rauv smelting mus rau ntau hom thawj smelting furnaces thiab sab nraud rauv refining.Tam sim no, bearing steel nrog lub peev xwm ntawm ntau tshaj 60 tons + LF / VD los yog RH + nruam casting + nruam dov txheej txheem yog siv los tsim bearing steel nyob rau hauv thiaj li yuav ua tau lub hom phiaj ntawm high quality, high efficiency thiab tsawg zog noj.Nyob rau hauv cov nqe lus ntawm kev kho cua sov txheej txheem, lub tsheb hauv qab lub cub tawg thiab lub hood rauv tau tsim rau hauv ib tug tsis tu ncua tswj qhov chaw annealing rauv rau kev kho cua sov.Tam sim no, kev kho cua sov tsis tu ncua ntawm lub tshuab hluav taws xob muaj qhov ntev tshaj plaws ntawm 150m, thiab cov qauv nodular ntawm cov kabmob steel yog ruaj khov thiab tsis sib xws, txheej decarburization yog me me, thiab lub zog noj tsawg.
Bearing steel yuav tsum muaj cov khoom nram qab no:
1. Kev tiv tauj siab qaug zog.
2. High abrasion tsis kam.
3. Siab elastic txwv thiab yield zog.
4. High thiab uniform hardness.
5, ib qho kev cuam tshuam toughness.
6. Kev ruaj ntseg zoo.
7, zoo corrosion inhibition kev ua tau zoo.
8. Cov txheej txheem ua tau zoo.
Bearing steel cov khoom siv:
Kev xaiv cov khoom siv steel bearing kuj yuav tsum tau yuav khoom tshwj xeeb.Rau cov ntaub ntawv bearing uas ua hauj lwm nyob rau hauv tshwj xeeb tej yam kev mob, raws li lawv cov kev cai tshwj xeeb, lawv kuj yuav tsum muaj cov khoom tshwj xeeb uas haum rau lawv tej yam kev mob, xws li: kub tsis kam, tsis kub tsis kam, corrosion kuj, Anti-kawg, anti-magnetic thiab lwm yam ntxwv.
Tag nrho hardened bearing steel feem ntau yog cov pa roj carbon chromium hlau, xws li GCr15, uas muaj cov ntsiab lus carbon txog li 1% thiab cov ntsiab lus chromium txog li 1.5%.Txhawm rau txhim kho hardness, hnav tsis kam thiab hardenability, qee qhov silicon, manganese, molybdenum, thiab lwm yam, xws li GCr15SiMn, yog tsim nyog ntxiv.Hom kabmob steel no muaj qhov tso zis ntau tshaj plaws, suav txog ntau dua 95% ntawm tag nrho cov kabmob steel tso tawm.
Carburizing bearing steel yog chromium, nickel, molybdenum alloy structural steel nrog cov ntsiab lus carbon ntawm 0.08 txog 0.23%.Qhov saum npoo ntawm cov kabmob yog carbonitrided los txhim kho nws cov hardness thiab hnav tsis kam.Cov hlau no yog siv rau kev tsim cov kabmob loj uas ua rau muaj kev cuam tshuam loj heev, xws li cov kabmob loj dov zeb, tsheb bearings, mining machine bearings, thiab railway tsheb bearings.
Stainless bearing steels muaj xws li carbon chromium stainless bearing steels, xws li 9Cr18, 9Cr18MoV, thiab nruab nrab carbon chromium stainless bearing steels, xws li 4Cr13, thiab lwm yam., uas yog siv los ua stainless thiab corrosion-resistant bearings.
High kub bearing steel yog siv nyob rau hauv high kub (300 ~ 500 ℃).Nws yuav tsum tau hais tias cov hlau muaj qee yam liab hardness thiab hnav tsis kam ntawm kev siv kub.Lawv feem ntau siv cov cuab yeej siv hluav taws xob kub ceev, xws li W18Cr4V, W9Cr4V, W6Mo5Cr4V2, Cr14Mo4 thiab Cr4Mo4V.
