Cored hlau, tseem hu ua cored steel hlau, yog cov khoom siv hlau siv hauv cov hlau metallgical engineering rau pw ua kom zoo nkauj. Nws muaj lub cold --} Tus kab mob steel hlau, nrog cov ntoo khaub ncaws ncig lossis duab plaub}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}. Los ntawm ib txoj kev pub mis cov hlau, ua kom cov neeg sawv cev ua kom sib sib zog ua kom ua tiav deoxidation, degassing kev kho mob, thiab cov kev hloov kho teeb meem. Nws tuaj yeem daws qhov teeb meem ntawm nozzle thaiv nyob rau hauv nruam casting ntawm txhuas deoxidized steel.
Cored wire refers to a wire body with a steel outer sheath and an inner core of ferroalloy powder, with a circular or rectangular cross-section. Nws yog siv los ua cov hlau pub mis nyob hauv chav pw ua kom zoo dua ntawm steelmaking ntxiv rau ntxiv cov neeg sawv cev ntxiv thiab cov neeg sawv cev. Nws tuaj yeem ua tau ncaj qha ntxiv rau hauv Molten Steel mus rau deoxidize, degas, thiab hloov kho tsis tau ntawm cov pob zeb tsis tu ncua ntawm cov hlau deox deoxunded.
Cored hlau yog hom xaim xaim tshwj xeeb, feem ntau muaj ntawm cov yas sab nraud sawb (lossis lwm yam khoom siv hlau) thiab cov khoom sab hauv. Thaum lub sijhawm cov txheej txheem ntau lawm, cov hlau txaij sib txawv undergoes deformation kev kho mob los ntawm ntau chais los ua tus qauv hollow. Tom qab ntawd, cov hmoov hlau uas yuav tsum muaj hmoov los yog cov khoom siv hlau txheem hlau ntxiv hauv lub raj raj hollow. Thaum kawg, los ntawm cov txheej txheem ntawm cov txheej txheem ntawm cov txheej txheem, cov hlau sawb nruj nreem qhwv cov hmoov nplej sab hauv lossis tsim cov khoom lag luam hlau txuas ntxiv. Hom hlau no muaj cov qauv sib luag ruaj khov, kev faib tsis tau hmoov, thiab yog siv dav hauv metallurgy, kev lag luam chemical, tshuab, thiab ntau lwm daim teb.
