Roll yog dab tsi?
Lub yob yog ib qho tseem ceeb ntawm cov dov zeb, uas siv lub siab tsim los ntawm ib khub lossis pab pawg ntawm cov yob los yob cov hlau. Nws yog feem ntau cuam tshuam los ntawm dynamic thiab zoo li qub load, hnav thiab kub hloov thaum dov. Raws li qhov tseem ceeb tshaj plaws noj ib feem ntawm cov dov zeb, cov txheej txheem ntau lawm ntawm yob yog qhov nyuaj.
Lub luag haujlwm ntawm cov yob yog hloov cov duab thiab qhov loj ntawm cov khoom siv hlau los ntawm kev dov, thiab tseem txhim kho lub zog thiab hardness ntawm cov khoom siv hlau. Ntxiv rau lub luag haujlwm hauv kev ua cov hlau, txhuas thiab lwm yam khoom siv hlau, yob kuj tseem siv dav hauv kev ua hlau, nkoj tsim, aerospace, tsheb tsim, khoom siv hluav taws xob thiab lwm yam haujlwm.
Dab tsi yog cov khoom ntawm yob?
Feem ntau, cov khoom siv los tsim cov yob yuav tsum muaj lub zog siab, siab hnav tsis kam, zoo corrosion kuj thiab qaug zog. Cov ntaub ntawv yob feem ntau suav nrog forged steel, cam khwb cia hlau, cam khwb cia hlau, cov hlau tsis muaj hlau thiab cov khoom siv hluavtaws. Cov khoom siv twg los xaiv nyob ntawm qhov yuav tsum tau ua thiab ib puag ncig ua haujlwm. Piv txwv li, forged steel yog cov khoom siv dav siv nrog lub zog siab thiab hnav tsis kam; Cam khwb cia hlau muaj zoo toughness thiab qaug zog kuj; Cam khwb cia hlau muaj qhov zoo ntawm kev hnav tsis kam thiab tus nqi qis. Kev kub ceev steel, alloy steel, carbide thiab lwm yam khoom siv rau cov menyuam. Kev kub ceev steel yob yog siv dav hauv kev tsim thiab ua cov ntawv txias dov, txias dov strip, iav, screws thiab lwm yam khoom. Alloy steel rolls yog tsim rau high-speed hlau dov, bar dov, strip dov thiab lwm yam teb. Carbide yob yog tsim rau dov, ua thiab txiav ntawm workpiece nto thiab sab hauv phab ntsa. Nws kuj yog siv dav hauv lub tshuab nruas, txoj kev cov menyuam, cement yeeb nkab tshuab, excavator thiab lwm yam khoom siv.
Ntxiv nrog rau cov hlau yob, muaj cov yob tsis yog hlau xws li ceramic yob, roj hmab yob thiab lwm yam.
Ceramic yob daim ntawv thov:
Kev lag luam hlau: Ceramic rolls yog siv nyob rau hauv ob qho tib si kub thiab txias dov ntau lawm kab hauv kev lag luam steel. Vim nws qhov kub thiab txias hnav tsis kam thiab tshuaj lom neeg ruaj khov, ceramic rollers tuaj yeem tiv taus qhov kub thiab txias, tuav lub neej ua haujlwm ntev, thiab tsis txhob ua paug rau cov phaj kub kub.
Automotive kev lag luam: Ceramic welding rollers tuaj yeem siv rau kev lag luam tsheb, feem ntau yog siv rau kev vuam ntawm tsheb sab hauv cov kav dej thiab cov kav dej. Cov cuab yeej vuam ua los ntawm cov khoom siv ceramic tuaj yeem ua tiav kev kub ceev thiab nruam vuam, kom ntseeg tau tias cov khoom welded muaj kev ruaj ntseg, sib xws, thiab tsis muaj hlau nplaum, rwb thaiv tsev, kub tsis kam.
Kev siv roj hmab yob:
Roj hmab yob muaj ntau yam kev siv, feem ntau yog siv ntau yam conveyors, elevator, siv conveyors, mixers thiab lwm yam machinery txhawb kev siv. Piv txwv li, nyob rau hauv cov menyuam ntawm txoj siv conveyor, cov menyuam roj hmab tuaj yeem txhawb nqa txoj siv conveyor thiab tswj kev ruaj ntseg ntawm kev ua haujlwm; Nyob rau hauv lub reversing nruas ntawm scraper conveyor, cov roj hmab cov menyuam tuaj yeem ua lub luag haujlwm hauv kev hloov cov kev taw qhia ntawm kev sib kis. Tsis tas li ntawd, cov menyuam roj hmab kuj tuaj yeem siv rau hauv qhov chaw pub mis ntawm lub pob zeb thiab lub khob hliav qab rau hauv cov khoom siv inclined rau kev ua ntxhia.
Daim ntawv thov zoo ntawm cov roj hmab rollers feem ntau yog nyob rau hauv lawv cov sealing zoo thiab hnav tsis kam. Nws tuaj yeem hloov kho rau feem ntau ntawm kev ua haujlwm, yog li nws ua lub luag haujlwm tsis tuaj yeem hloov pauv hauv kev tsim khoom.
Cov txheej txheem yob tsim muaj cov kauj ruam hauv qab no:
Kev npaj cov khoom siv raw: Cov khoom siv raw ntawm cov yob feem ntau suav nrog cam khwb cia hlau, hlau, alloy, thiab lwm yam. Xaiv cov ntaub ntawv raw uas tsim nyog raws li cov txheej txheem yob thiab kev ua tau zoo, thiab xyuas cov khoom siv raw kom ntseeg tau tias lawv cov khoom ua tau raws li qhov xav tau.
Casting: Cov pwm yog tsim raws li qhov loj thiab cov duab ntawm lub yob, thiab tom qab ntawd cov khoom siv yaj yaj yog nchuav rau hauv pwm, tos kom nws khov. Nyob rau hauv cov txheej txheem no, tsis xws li pouring kub, pouring ceev thiab txias ceev yuav tsum tau tswj los xyuas kom meej lub tiav ntawm yob nto thiab qhov ceev ntawm lub internal qauv.
Kev kho cua sov: Txhawm rau txhim kho lub hardness thiab hnav tsis kam ntawm yob, kev kho cua sov yuav tsum tau ua. Cov txheej txheem kev kho cua sov feem ntau suav nrog quenching thiab tempering. quenching yog ua kom sov cov khoom yob rau lub xeev kub, thiab tom qab ntawd los tsim cov txheej txheem nyuaj ntawm nws qhov chaw los ntawm kev ua kom txias sai. Tempering yog kom sov lub quenched yob mus rau lub xeev kub, thiab ces sib npaug ntawm cov qauv los ntawm kev ua kom txias qeeb los txhim kho nws cov toughness thiab lub zog.
Machining: Machining yog cov kauj ruam kawg hauv kev tsim cov yob, suav nrog roughing, precision machining thiab sib tsoo. Nyob rau hauv roughing, nws yog tsim nyog los txiav, zeb thiab laum lub yob tom qab casting. Nyob rau hauv precision machining, ntau yam duab thiab qhov ntau thiab tsawg ntawm cov yob yuav tsum tau tsim los ntawm kev tig, sib tsoo, thiab lwm yam. Thaum kawg, qhov precision thiab tiav ntawm yob nto yog txhim kho los ntawm kev sib tsoo.
Kev soj ntsuam zoo: Kev tshuaj xyuas zoo ntawm cov yob tsim, suav nrog qhov loj me, zoo li, nto tiav thiab lwm yam ntawm qhov kev xeem kom paub tseeb tias nws ua tau raws li qhov yuav tsum tau ua.
Cov txheej txheem tsim khoom sib txawv muaj qhov sib txawv ntawm cov khoom ntawm cov yob. Piv txwv li, kev siv cov txheej txheem kev kho cua sov tuaj yeem txhim kho qhov hnav tsis kam thiab hardness ntawm yob, tab sis nws lub zog thiab lub zog yuav raug txo. Yog li ntawd, hauv kev tsim khoom tiag tiag, nws yog ib qho tsim nyog yuav tsum xaiv qhov tsim nyog thiab kev sib xyaw ua ke raws li kev siv thiab kev ua haujlwm ntawm cov yob.
Qhov twgsib tsoo logyog xaiv rau kev sib tsoo ntawm yob?
Txij li ntau hom yob yog ua los ntawm cov ntaub ntawv sib txawv, peb tseem xaiv lub log sib tsoo raws li cov khoom siv ntawm cov khoom ua haujlwm.
Piv txwv li, sib tsoo forged steel, cam khwb cia hlau, cam khwb cia hlau, high-speed steel roller, peb tuaj yeem siv corundum lossis CBN sib tsoo log. Sib tsoo kub, tsis yog hlau xws li ceramic, roj hmab cov menyuam, peb siv silicon carbide lossis pob zeb diamond sib tsoo log. Cov kev xaiv tshwj xeeb ntawm kev sib tsoo log thiab kev xaiv ntawm granularity hardness ntawm kev sib tsoo log tuaj yeem xa mus rau cov hauv paus ntsiab lus ntawm kev sib tsoo log xaiv sib koom ua ntej lossis sab laj nrog peb.
