Cored Wires Taw Qhia

Cored xov hlau yog qhov tseem ceeb hauv kev tsim cov hlau thiab lwm yam hlau alloys. Cov xov hlau no tau ntxiv rau cov hlau molten los hloov nws cov tshuaj muaj pes tsawg leeg thiab lub cev lub cev. Cored xov hlau tau tsim nyob rau hauv 1970s thiab txij li thaum revolutionized steelmaking kev lag luam.
Cored xov hlau yog tsim los ntawm cov hlau sheath uas muaj cov hmoov flux-cored. Cov hmoov yog tsim los ntawm ntau yam alloys thiab minerals uas yog siv los kho cov tshuaj muaj pes tsawg leeg ntawm cov hlau molten. Thaum lub cored hlau yog nkag mus rau hauv da dej, lub tshav kub ntawm cov hlau molten melts lub txheej sheath, thiab cov hmoov puab tawm. Cov hmoov no dissolves nyob rau hauv lub molten hlau, hloov nws muaj pes tsawg leeg thiab refining nws cov qauv.
Cov txiaj ntsig ntawm kev siv cov xov hlau cored hauv kev tsim cov hlau yog ntau heev. Lawv tso cai rau kev tswj kom meej meej ntawm cov tshuaj muaj pes tsawg leeg ntawm cov hlau. Cored xov hlau tuaj yeem siv los hloov kho me me rau cov khoom siv hlau, uas tuaj yeem txhim kho nws lub zog, ductility, thiab lwm yam zoo. Lawv kuj tso cai rau kev siv cov peev txheej ntau dua, vim tias cov khoom siv tsawg dua yuav tsum tau ua kom tiav cov khoom xav tau.

Cored hlau thev naus laus zis tau dhau los ntev txij li nws tau qhia hauv xyoo 1970s. Niaj hnub no, cov xov hlau cored muaj nyob rau hauv ntau qhov ntau thiab tsawg, sib xyaw, thiab hom flux, tso cai rau kev hloov pauv ntau dua hauv kev tsim steel. Qee cov xov hlau cored kuj muaj cov kab lus xws li titanium, boron, lossis txhuas, uas tuaj yeem txhim kho cov khoom hlau ntxiv.
Txawm hais tias muaj ntau yam txiaj ntsig ntawm cov xov hlau cored, muaj qee qhov teeb meem cuam tshuam nrog lawv siv. Ib qho kev sib tw yog lub peev xwm rau slag buildup, uas tuaj yeem cuam tshuam nrog cov txheej txheem ntau lawm. Qhov teeb meem no tuaj yeem txo tau los ntawm kev ua tib zoo xaiv hom flux siv nyob rau hauv cored hlau. Lwm qhov kev sib tw yog tus nqi ntawm cov xov hlau cored, uas tuaj yeem siab dua lwm txoj kev alloying. Txawm li cas los xij, qhov tseeb thiab kev ua haujlwm ntawm cored hlau thev naus laus zis ua rau nws muaj txiaj ntsig kev nqis peev rau ntau tus neeg tsim khoom.
Hauv kev xaus, cov xov hlau cored tau hloov pauv kev lag luam steelmaking los ntawm kev muab txoj hauv kev zoo dua thiab meej ntawm kev hloov cov khoom sib xyaw thiab cov khoom ntawm cov hlau molten. Txawm hais tias qee qhov kev sib tw, cov xov hlau cored tseem ua lub luag haujlwm tseem ceeb hauv kev tsim cov hlau thiab zoo li yuav ua li ntawd rau xyoo tom ntej.

Q: Koj puas yog cov chaw tsim khoom lossis cov tub luam?
A: Peb yog cov chaw tsim khoom tiag tiag, peb tsis tsuas yog tuaj yeem muab cov khoom lag luam zoo nrog tus nqi zoo tshaj plaws, tab sis kuj tuaj yeem muab cov kev pabcuam zoo tshaj plaws ua ntej muag thiab kev pabcuam tomqab muag.

Q: Koj muaj cov qauv dab tsi?
A: Peb cov khoom ua tau raws li cov qauv, xws li ASTM, ASME, AMS, DIN, JIS thiab lwm yam.Qhov kev xeem thib peb yog txhua yam muaj rau peb.

Q: Koj lub sijhawm ua haujlwm yog dab tsi?

A: Feem ntau nws xav tau li ntawm 15- 20 hnub tom qab tau txais PO.
