Cov txheej txheem casting ntawm txhuas ingots yuav tsum tau nchuav molten aluminium rau hauv pwm, qhov twg nws txias thiab solidifies rau hauv ib lub billet. Cov kauj ruam tseem ceeb hauv kev tsim khoom no cuam tshuam rau tag nrho qhov zoo ntawm cov khoom kawg. Thaum cov txheej txheem no, cov kua txhuas ua kua crystallization, hloov mus rau hauv cov khoom txhuas. Ob txoj hauv kev casting yog nruam nruam thiab ntsug semi- nruam casting.
Nruam Casting
Nruam casting tuaj yeem muab faib ua ob hom: sib xyaw rauv casting thiab sab nraud casting. Ob txoj kev siv cov tshuab nrum nruam.
Kev sib xyaw rauv casting pib los ntawm kev thauj khoom molten aluminium rau hauv qhov cub sib xyaw. Tom qab batching, aluminium yog poured rau hauv lub cub tawg, stirred, thiab refined siv flux kom tshem tawm impurities. Qhov sib tov yuav tsum nyob rau tsawg kawg 30 feeb kom paub meej. Thaum npaj txhij, lub cub tawg ua ke nrog cov pwm ntawm lub tshuab casting, thiab cov txhuas yog nchuav, txo qis oxidation thiab txaws. Cov kua aluminium ntws los ntawm ib qho pwm mus rau lwm qhov, txias thiab ua kom khov rau hauv cov khoom siv. Txoj kev no yuav tsum tau dej txias, siv li ntawm 8-10 tons ntawm dej ib tuj ntawm txhuas kua. Feem ntau cov teeb meem nyob rau hauv nruam casting muaj xws li porosity, uas yog tshwm sim los ntawm high casting kub thiab ntau roj cov ntsiab lus. Slag suav nrog tej zaum yuav tshwm sim los ntawm cov slag tsis huv los yog qis aluminium kub. Cov teeb meem zoo li corrugation thiab flash tuaj yeem tshwm sim los ntawm kev ua haujlwm tsis raug lossis cov khoom siv tsis raug. Kev tawg yog feem ntau yog tshwm sim los ntawm qhov kub tsis raug, thaum cov khoom sib cais tuaj yeem tshwm sim vim tsis sib xws thaum lub sij hawm ua cov txheej txheem alloy.
External casting yog ncaj qha pouring los ntawm ib tug ladle mus rau lub tshuab casting. Nws feem ntau yog siv thaum cov khoom siv tsis tuaj yeem ua kom muaj qhov sib xyaw ua kom sov lossis thaum cov khoom siv qis dua. Kev tuav lub ntsuas kub kom zoo hauv lub ladle yog qhov tseem ceeb kom ua tiav qhov sib xws ntawm cov khoom siv txhuas.
Vertical Semi-Nruam Casting
Vertical semi- nruam casting feem ntau yog siv rau txhuas hlau ingots, phaj ingots, thiab ntau yam deformed alloys. Cov txheej txheem pib los ntawm pouring molten txhuas rau hauv ib lub qhov cub sib tov, qhov twg additives xws li Al-B, Al-Ti-B, thiab refining agents yog qhia rau kev txhim kho nto qauv. Preheating pwm Cheebtsam thiab lubricating lub crystallizer lub puab phab ntsa yog qhov tseem ceeb los xyuas kom meej ib tug du casting txheej txheem. Thaum lub sij hawm casting txheej txheem, cov txhuas ntws los ntawm qhov sib tov rauv los ntawm ib lub phaj faib rau hauv crystallizer, qhov uas nws solidifies los ntawm hauv qab thiab sab. Lub tshuab casting lub chassis nqis los ntawm kev tswj tus nqi, tso cai rau maj mam ua kom muaj zog, thaum cov dej txias txau muab kev tswj qhov kub thiab txias thoob plaws hauv cov txheej txheem.
Cov teeb meem tshwm sim nyob rau hauv ntsug ib nrab- nruam nruam muaj xws li cov kab nrib pleb, uas tuaj yeem tshwm sim los ntawm qhov kub thiab txias, nrawm nrawm, lossis txias tsis txaus. Slag inclusions tuaj yeem tshwm sim los ntawm kev hloov pauv hauv cov hlau molten lossis tshem tawm slag tsis raug. Kev kaw txias tuaj yeem tshwm sim vim qhov tsis sib xws ntawm txhuas qib lossis qhov kub tsis raug, thaum lub qhov hws feem ntau tshwm sim vim qhov kub thiab txias ntawm cov pa roj hauv qhov ingot. Cov chaw ntxhib yuav tshwm sim los ntawm lubrication tsis txaus lossis qhov txias tsis sib xws, ua rau muaj qhov tsis zoo ntawm cov khoom tiav.
