Thaum siv cov khoom siv quav ciab, yaj pwm casting kuj hu ua "poob ciab casting". Melting pwm casting feem ntau yog hais txog cov txheej txheem casting ua los ntawm cov khoom siv molten, txheej ob peb txheej ntawm cov khoom siv refractory ntawm cov duab saum npoo, thiab tom qab ntawd melting cov duab thiab tawm lub plhaub, thiaj li tau txais cov casting yam tsis muaj kev faib tawm nto, thiab sau cov xuab zeb thiab ncuav tom qab. kub kub roasting. Vim tias qhov zoo li no tau siv dav hauv cov ntaub ntawv siv quav ciab los tsim, yog li cov molding molding feem ntau hu ua " poob ciab casting.
Melting casting tseem hu ua txoj kev ploj lawm. Txoj kev poob ciab yog ua kom siv quav ciab los ua cov pwm, thiab tom qab ntawd ntawm cov quav pwm coated nrog cov av nkos, qhov no yog cov av nkos. Tom qab cov av pwm tau qhuav, ci rau hauv cov pwm ceramic. Thaum roasting, tag nrho cov wax pwm yog melted thiab ploj, tawm tsuas yog lub lauj kaub tais diav. Feem ntau, lub qhov ncauj pouring yog sab laug, thiab ces cov kua tooj liab yog poured los ntawm lub qhov ncauj pouring. Tom qab txias, cov khoom siv yuav tsum tau ua.
Cov hom hlau uas tuaj yeem tsim los ntawm cov pwm casting txheej txheem yog carbon steel, alloy steel, tshav kub resistant alloy, stainless hlau, precision alloy, ruaj hlau nplaum alloy, bearing alloy, tooj liab alloy, aluminium alloy, titanium alloy, thiab lwm yam.
Manufacturing ntawm melt hom:
1. Cov khoom siv tuag (feem ntau npaj nrog cov khoom siv quav ciab, cov khoom siv ntuj thiab cov yas (synthetic resin))
2. Kev npaj thiab rov ua cov khoom pwm
3. Kev tsim cov yas pwm thiab cov qauv
Kev tsim khoom ntawm hom plhaub
1. Khoom siv rau kev tsim cov hom plhaub
Cov ntaub ntawv refractory: quartz thiab corundum, nrog rau txhuas silicate, xws li refractory av nplaum, aluminium vanadium av, coke pob zeb, thiab lwm yam. Qee zaum kuj muaj zircon, magnesia (MgO), thiab lwm yam.;
Binder: silicic acid colloid tov, tsuas yog silica acid sol, xws li ethyl silicate hydrolysate, dej iav, thiab silica sol. Dej iav plhaub yog ib qho yooj yim rau deform, tawg, nrog rau qhov loj me qhov tseeb thiab qhov chaw du yog qhov tsis zoo, kev ruaj ntseg ntawm silicon sol yog qhov zoo, tuaj yeem khaws cia rau lub sijhawm ntev, lub plhaub tsis muaj tus neeg sawv cev tshwj xeeb, tab sis silica gel ntawm yaj pwm wetting yog me ntsis pluag, lub plhaub hardening txheej txheem yog ib tug qhuav txheej txheem, xav tau ib tug ntev lub sij hawm
2. txheej txheem ua lub plhaub
