Metallurgical Materials Cored Hlau

Metallurgical cov ntaub ntawv cored hlau yog ib hom pre-txheej hlau casting txoj kev uas tso cai rau siv ib tug tib electrode rau ntau daim ntaub ntawv. Feem ntau, ib co cored hlau yog dov mus rau hauv ib lub kauj thiab ces muab los ntawm lub nozzle los yog phom uas txuas nrog ib tug hlau feeder. Cov hlau cored tuaj yeem ua los ntawm ntau yam ntaub ntawv, suav nrog carbon, silicon, aluminium, thiab magnesium, rau npe ob peb. Cov hlau feem ntau yog siv los ntxiv qee yam khoom lossis cov khoom siv rau cov hlau molten thaum lub sij hawm casting txheej txheem.
Kev siv cov hlau cored tuaj yeem txhim kho qhov zoo ntawm cov khoom cam khwb cia los ntawm kev txo cov impurities thiab txhim kho cov khoom xws li lub zog, durability, thiab corrosion kuj. Cored hlau tau tshwj xeeb hauv kev tsim cov hlau thiab cov hlau tsis muaj hlau xws li tooj liab, txhuas, thiab magnesium.

Cov txheej txheem ntawm kev siv cored hlau yog qhov yooj yim. Cov hlau yog threaded los ntawm cov hlau feeder thiab ces muab los ntawm lub nozzle los yog phom. Raws li nws tau noj los ntawm, cov hlau pib yaj thiab cov khoom lossis cov khoom muaj nyob hauv cov tub ntxhais raug tso tawm. Cov txheej txheem txuas ntxiv mus txog thaum cov khoom xav tau ntxiv rau cov hlau molten.
Ib qho ntawm qhov zoo ntawm kev siv cored hlau yog tias nws tso cai rau kev tswj hwm tus nqi thiab hom khoom ntxiv rau cov hlau. Qhov no yog qhov tseem ceeb tshwj xeeb tshaj yog thaum nws los txog rau kev ntxiv cov khoom xws li carbon thiab silicon, uas tuaj yeem cuam tshuam rau qhov kawg ntawm cov khoom cam khwb cia. Tsis tas li ntawd, cored hlau tuaj yeem siv los ntxiv cov ntaub ntawv uas nyuaj lossis kim ntxiv los ntawm lwm txoj hauv kev, ua rau nws muaj txiaj ntsig zoo thiab ntau yam kev daws teeb meem.
Zuag qhia tag nrho, kev siv cov ntaub ntawv metallurgical cored hlau yog cov cuab yeej tseem ceeb hauv cov txheej txheem hlau casting. Nws lub peev xwm los ntxiv cov nqi ntawm ntau yam ntaub ntawv ua rau nws yog ib txoj hauv kev los txhim kho cov khoom zoo ntawm cov khoom cam khwb cia. Raws li thev naus laus zis txuas ntxiv mus, nws yuav zoo li tias cov xov hlau cored tseem yuav ua lub luag haujlwm tseem ceeb hauv kev tsim cov khoom zoo.

Q: Peb puas tuaj yeem tuaj xyuas koj lub Hoobkas?
A: Zoo siab txais tos thaum peb muaj koj lub sijhawm peb yuav tuaj tos koj.

Q: Koj puas muaj kev tswj xyuas zoo?
A: Yog, peb tau txais BV, SGS authentication.

Q: Koj lub sijhawm xa khoom ntev npaum li cas?
A: Feem ntau nws yog 7-14 hnub yog tias cov khoom muaj nyob hauv Tshuag. los yog nws yog 25-45 hnub yog tias cov khoom tsis nyob hauv Tshuag, nws yog raws li
kom muaj nuj nqis.

Q: Peb puas tuaj yeem tau txais qee cov qauv?
A: Yog lawm, peb tuaj yeem muab cov qauv dawb tab sis tsis them tus nqi thauj khoom. Yog tias koj tso qhov kev txiav txim tom qab paub meej cov qauv, peb yuav rov qab koj cov khoom xa tuaj los yog txiav tawm ntawm tus nqi xaj.
