Ntau lub ntsiab lus ntawm kev xaiv ua ntej abrasive

Xeb hlau tsis zoo nyob txhua qhov chaw, txhua lub sijhawm

Txhawm rau tiv thaiv xeb hlau, txoj hauv kev feem ntau yog siv cov txheej txheej tiv thaiv kom tsis txhob muaj cov nplaim steel. Qhov saum npoo yuav tsum raug muab ntxuav ua ntej txheej tiv thaiv. Pua pua ntawm cov khoom lag luam thiab cov chaw lag luam suav nrog lub nkoj, chaw tso tsheb hlau luam, txuas hniav, cov qauv siv hlau, chaw nres tsheb fais fab, tsheb, chaw tsheb, khoom siv tub rog, khoom siv dav hlau, thiab lwm yam yuav tsum kho kom zoo ua ntej txheej. Hlau abrasive yog qhov ua tau zoo tu nruab nrab.

Nws yog xim hlau abrasives

Feem ntau, muaj cam khwb cia steel txhaj tshuaj (cov pa roj carbon monoxide siab tua thiab tsawg cov carbon steel txhaj tshuaj), steel grit, hlau tua, hlau grit, stainless hlau txiav hlau / conditioned txhaj koob tshuaj tivthaiv, stainless hlau gritsteel txiav hlau, bearing steel grit, lwm yam zoo li cov hlau tsis muaj zog tsis yooj yim tawg, plua plav plua plav qis, tsis siv neeg tsawg, kev ua haujlwm siab tu, thiab cov khoom zoo txhua yam. Nws tuaj yeem txo qhov kev noj kom tsawg ntawm cov neeg siv kawg, yog li txo tus nqi thiab txo emissions.

Yog li cov lus nug yog, yuav ua li cas xaiv cov ntawv zoo hlau abrasives?

Txhawm rau kom paub tseeb tias cov txiaj ntsig kev kho saum npoo av yog qhov ua tiav raws li tus qauv, ob qhov ntsuas qhov tseem ceeb ntawm cov hlau abrasives: tu kev ua tau zoo thiab siv.

Ntau qhov yuam kev hauv kev xaiv ntawm cov cam khwb cia steel txhaj tshuaj:

Puas yog cov cam khwb cia steel txhaj rounder qhov zoo dua?

Yog cov particle loj npaum li cas yam, zoo dua?

Lub ci qhov tsos, zoo dua?

Puas yog cov cam khwb cia steel txhaj rounder qhov zoo dua?

Teb: Tsis tau.

Hauv kev tsim cov txheej txheem thiab npaj cov phiaj hlau, cov hlau molten txias los ntawm cov kua los ua khoom, thiab ntsws thaum lub sijhawm txias. Qhov kev ziab no yog nqa tawm hauv lub xeev dawb, thiab tsis muaj riser zoo li nchuav cov nruas los ntawm cov hlau ua kom cov hlau ntim ntawm qhov ntim tom qab txo qis, yog li elliptical hais nrog sab hnub poob. Qhov zoo li no tau ua tiav txaus shrinkage, thiab cov duab tsis sib npaug tab sis tus qauv yog ntom ntom. Txawm li cas los xij, yog tias cov ntawv txhaj tshuaj steel uas tsis tau cog lus tag nrho, tus qauv yuav tsis ntom, muaj cov teeb meem sab hauv xws li shrinkage porosity thiab shrinkage kab noj hniav.

Pov lub zog E = 1 / 2mv2, yog tias tus qauv yog ntom ntom, nrog tib lub ntim, qhov loj ntawm qhov nthwv zoo M yog, cuam tshuam rau lub zog loj dua, thiab kuj tsis yooj yim tawg. Txoj kev no, nws tsis yog qhov tseeb: rounder steel raug tua zoo dua.

Yog lub noob nplej loj ntawm cov hlau tau tua ntau cov qauv, zoo dua?

Teb: Tsis tau.

Hauv thaj teb ntawm kev tu vaj tse, saum npoo ntawm qhov haujlwm kom raug muab ntxuav lossis txau yuav tsim cov pits ntawm qhov chaw huv. Tsuas yog thaum lub qhov thiab pits sib tshooj sib tshooj nkaus, tag nrho cov saum npoo tuaj yeem muab ntxuav kom huv.

Qhov sib txawv loj npaum li cas cov particle loj ntawm steel txhaj koob tshuaj tiv thaiv yog, ntev dua nws yuav siv sij hawm kom ncav cuag qhov sib tshooj ntawm qhov sib tshooj.Rau steel txhaj tshuaj nrog qee qhov loj me feem ntau sib xyaw, qhov loj steel txhaj tshuaj feem ntau yog siv rau kev ntxuav, thiab cov steel txhaj tshuaj yuav ntxuav kev sib tshuam nruab nrab ntawm thaj chaw raug kho los ntawm kev siv loj-loj steel txhaj tshuaj

Lub ci qhov tsos, zoo dua?

Teb: Tsis tau.

Tam sim no nws muaj ob hom ntawm cov pa roj carbon monoxide siab tua: ib qho quenching steel txhaj tshuaj thiab ob chav quenching steel txhaj. Nws yog qhov nyuaj kom paub qhov txawv ntawm qhov muaj pes tsawg leeg, ua tawv tawv, thiab ua cov duab hlau. Txawm li cas los xij, ob chav quenched steel txhaj tshuaj muaj qhov zoo thiab muaj lub zog zoo lub neej, cov hmoov nplej ntawm tib lub quenching steel txhaj tshuaj yog cov ntxhib thiab lub neej tsis muaj lub zog qis.Qhov ib qho quenching steel tua tsis ua tiav nrog cov cua kub thiab quenching, Fe3O4 oxide zaj duab xis tsim rau nplaim yog nyias, nws zoo nkaus li zoo ci; thaum cov hlau tua tom qab kev kho mob thib ob , Fe3O4 zaj duab xis nyob rau saum npoo ua ntom nti, tsis cuam tshuam lub teeb, thiab tsis zoo li ci. Yog li lub ci ntsa iab saum npoo tsis ntsuas cov khoom lag luam zoo dua, tab sis yog tias nws yog ob npaug quenching steel tua lossis tsis yog qhov teeb meem tseem ceeb dua.
