Yam ntxwv ntawm Multemp SRL

1.Qhov Khoom Qis Qis

Siv cov ntaub ntawv tseem ceeb ua kom huv, ua tib zoo xaiv cov tshuaj ntxiv thiab cov roj hauv paus nrog cov viscosity tsim nyog, cov roj tau tsim hauv cov txheej txheem tshwj xeeb hauv peb cov nroj tsuag tswj cov hmoov av. Raws li qhov tshwm sim, nws txhawb kom txo qis suab nrov.

2.Lub neej

Cov roj muaj lub neej ua haujlwm ntau zaus ntau dua li qhov kub thiab txias-ntau cov roj nyob hauv khw, ua kom muaj roj nplua nyeem ntev dua ntawm qhov kub. Nyob rau hauv cov xwm txheej dav dav, nws paub qhov tseem ceeb ntev mus los ntawm kev hloov pauv hloov lossis pub mis.

3.Low Torque Khoom

Cov roj tswj cov cua sov tsim los ntawm cov kabmob, txo cov roj ua rau lub zog poob.

Yam Yuav Tsum Tau Ua Rau Cov Kab Hlau

Raws li qhov xav tau saum toj no rau kev nqa cov hlau, cov hauv qab no yuav tsum tau muab tso rau pem hauv ntej rau cov hlau zoo ntawm cov kabmob hlau;

1. Yuav tsum muaj cov tshuaj muaj pes tsawg leeg.

Kev coj cov hlau feem ntau yog cov pa roj carbon siab chromium bearing hlau, uas yog, cov hlau hypereutectoid nrog cov ntsiab lus carbon txog li 1%, ntxiv txog 1.5% ntawm chromium, thiab me me ntawm manganese thiab silicon. Chromium tuaj yeem txhim kho kev kho cua sov, ua kom tawv tawv, ua kom zoo ib yam ntawm cov qauv, thiab tiv thaiv kom sov. Nws kuj tseem tuaj yeem txhim kho xeb tsis kam thiab kev ua haujlwm sib tsoo ntawm cov hlau.

Tab sis thaum cov ntsiab lus chromium ntau dua 1.65%, tom qab quenching, nws yuav ua rau cov hlau austenite khaws cia, txo qhov hnyav thiab qhov ruaj khov ntawm qhov ntev, nce qhov tsis sib xws ntawm carbides, thiab txo qhov cuam tshuam qhov tawv thiab qaug zog ntawm cov hlau. Vim li no, cov ntsiab lus chromium hauv cov pa roj carbon siab chromium bearing hlau feem ntau tswj qis dua 1.65%. Tsuas yog los ntawm kev tswj hwm cov tshuaj lom neeg muaj pes tsawg leeg ntawm cov kabmob hlau tuaj yeem ua tus qauv thiab tawv uas ua tau raws li qhov ua tau zoo tau los ntawm cov txheej txheem kho cua sov.

2. Ntau qhov tseeb qhov xav tau.

Rau cov kub-kuav los tiag thiab annealed tuav forged ntawm kev kub ceev tshuab tu siab, yuav tsum muaj qhov siab dua qhov tseeb qhov xav tau.

Rolling bearing steel yuav tsum muaj qhov siab ntawm cov hlau vim tias feem ntau ntawm cov kabmob yuav tsum tau ua lub siab ua. Txhawm rau txuag cov ntaub ntawv thiab txhim kho kev ua haujlwm tau zoo, feem ntau ntawm cov kabmob tau tsim los ntawm forging, cov hlau hlau tau tsim los ntawm cov lus txias lossis kub dov, thiab cov menyuam me me kuj tseem tsim los ntawm cov lus txias. Yog tias qhov ntsuas qhov tseeb ntawm cov hlau tsis siab, qhov loj me thiab qhov hnyav tsis tuaj yeem suav qhov raug, thiab cov khoom lag luam zoo ntawm cov kabmob tsis tuaj yeem lav tau, thiab nws yooj yim ua rau puas tsuaj rau cov cuab yeej thiab pwm.

3. Tsis nruj heev purity yuav tsum tau.

Kev huv ntawm cov hlau hais txog tus naj npawb ntawm cov xim tsis suav nrog hauv cov hlau. Qhov siab dua qhov huv, tsawg dua cov uas tsis yog xim hlau suav nrog hauv cov hlau. Kev phom sij xws li oxides thiab silicates hauv cov kabmob hlau yog qhov laj thawj tseem ceeb uas ua rau kom ntxov ntxov nkees ntawm cov kabmob thiab txo qis lub neej ntawm cov kabmob. Tshwj xeeb, kev sib txhuam me me yog qhov phom sij tshaj plaws, vim tias lawv yooj yim rau tev tawm ntawm cov hlau txheej thaum ua, uas cuam tshuam loj heev rau qhov zoo ntawm qhov chaw ntawm cov kabmob tom qab ua tiav. Yog li, txhawm rau txhim kho kev pabcuam lub neej thiab kev ntseeg tau ntawm cov kabmob, cov ntsiab lus ntawm kev suav nrog hauv cov kabmob hlau yuav tsum raug txo.

4. Kev txwv nruj rau lub zog qis thiab lub koom haum micro (siab zog).

Lub macrostructure ntawm cov kabmob hlau hais txog qhov dav dav, qhov chaw porosity thiab cais. Lub microstructure (kev nthuav dav siab) suav nrog cov qauv txheej txheem ntawm cov hlau, carbide network, band thiab cov kua dej nag. Carbide kua yog qhov nyuaj thiab nkig, thiab nws qhov kev phom sij yog tib yam li ntawm qhov nkig nkig. Reticulated carbides txo qhov cuam tshuam ntawm cov hlau thiab ua rau nws cov qauv tsis sib xws, uas yooj yim rau deform thiab tawg thaum lub sij hawm quenching. Banded carbides cuam tshuam rau kev pleev xim thiab ua kom sov thiab ua kom sov thiab ua rau lub zog qaug zog. Qhov zoo thiab qhov tsis zoo ntawm kev nthuav dav qis thiab siab siab muaj qhov cuam tshuam zoo rau kev ua haujlwm thiab kev pab lub neej ntawm cov menyuam dov. Yog li ntawd, muaj cov kev cai nruj rau cov qauv qis thiab siab hauv cov qauv khoom siv.

5. Tshwj xeeb tshaj yog nruj nruj rau qhov tsis xws luag thiab sab hauv tsis xws luag.

Rau cov kabmob hlau, qhov tsis xws luag muaj xws li cov kab nrib pleb, khawb av, khawb, nti, oxide nplai, thiab lwm yam, thiab qhov tsis xws sab hauv suav nrog qhov me me, qhov ua npuas dej, qhov me me, qhov porosity hnyav thiab sib cais. Cov kev tsis xws no muaj kev cuam tshuam loj rau kev ua cov kabmob, kev ua tau zoo thiab lub neej ntawm cov kabmob, thiab nws tau hais meej meej hauv cov txheej txheem cov khoom coj los uas cov tsis xws luag no tsis raug tso cai.

6. nruj carbide inhomogeneity yuav tsum tau.

Hauv kev nqa cov hlau, yog tias muaj kev faib tawm tsis sib xws loj ntawm carbides, nws yooj yim ua rau tsis sib xws hauv cov qauv thiab tawv thaum txheej txheem kho cua sov, thiab qhov tsis sib xws ntawm cov qauv hlau muaj kev cuam tshuam ntau dua rau kev sib cuag qaug zog. Ib qho ntxiv, carbide inhomogeneity hnyav tuaj yeem yooj yim ua rau tawg hauv cov kabmob thaum lub sijhawm ua kom txias thiab txias, thiab carbide inhomogeneity kuj tuaj yeem ua rau txo qis hauv lub neej ntawm cov kabmob. Yog li ntawd, hauv cov txheej txheem cov khoom coj los, muaj cov yam ntxwv tshwj xeeb rau qhov sib txawv tshwj xeeb ntawm cov hlau. yuav tsum tau tshwj xeeb.

7. nruj nruj rau qhov tob ntawm txheej decarburization txheej.

Hauv cov txheej txheem cov khoom coj los, muaj cov kev cai nruj rau txheej decarburization ntawm cov hlau. Yog tias txheej txheej decarburization txheej txheem dhau qhov tshwj xeeb tau teev tseg ntawm tus txheej txheem, thiab nws tsis raug tshem tawm tag nrho thaum ua cov txheej txheem ua ntej kho cua sov, nws yuav raug tshem tawm thaum txheej txheem kho cua sov. Nws yog ib qho yooj yim los tsim quenching tawg, ua rau seem seem.
