Hauv kev tsim cov khoom lag luam txhuas, kev tswj kom zoo thiab kev tswj hwm ntawm cov hlau molten hlau yog qhov tseem ceeb los xyuas kom meej qhov ua tau zoo thiab zoo ntawm kev ua haujlwm casting.Ib qho tseem ceeb ntawm kev tswj xyuas qhov kev tswj no yog aluminium stopper cone.Qhov tshwj xeeb refractory no ua lub luag haujlwm tseem ceeb hauv tapping molten aluminium los ntawm lub cub tawg mus rau qhov qis qis casting.Kab lus no tshawb txog kev ua haujlwm thiab qhov tseem ceeb ntawmaluminium stopper conesnyob rau hauv cov khoom siv aluminium.
Flow Control: Tus qauv tsim ntawm lub khob hliav qab tso cai rau kev tswj cov kua hlau molten.Cov yam ntxwv no ua kom muaj kev ruaj khov thiab tsis sib xws ntawm cov hlau tawm, tiv thaiv kom tsis txhob muaj kev puas siab puas ntsws thiab cov pwm tsis sib haum.Tus tswj ntws tus nqi kuj tseem nyob rau hauv kev zam casting qhov tsis xws luag thiab ua tau zoo dua casting yields.
Thermal rwb thaiv tsev: Lub khob hliav qab stopper ua los ntawm cov khoom siv aluminium fiber ntau, uas tsis yog-stick aluminium thiab tsis-slagging.Qhov no pab tswj qhov kub thiab txias ntawm cov hlau molten thaum nws dhau los ntawm lub khob hliav qab, txo cov cua sov kom tsawg thiab ua kom pom kev zoo tshaj plaws.Los ntawm kev muab cov rwb thaiv tsev, aluminium silicate cov khoom hauv kev ua tiav cov khoom zoo ntawm aluminium alloys,txo qhov kev pheej hmoo ntawm shrinkage defects thiab kom ntseeg tau qhov tseeb qhov tseeb ntawm cov khoom cam khwb cia.
Resistance rau Corrosion thiab Erosion: Cov txhuas lub khob hliav qab yog feem ntau yog tsim los ntawm cov khoom zoo refractory uas muaj superior tiv thaiv corrosion thiab yaig los ntawm cov txhuas molten.Stopper cone siab hardness, lub neej ntev kev pab cuam no ua kom lub txhuas stopper cone durability thiab kev ua tau zoo tshaj lub sij hawm ntev ntawm kev siv.
Kev Ruaj Ntseg thiab Kev Kho Kom Zoo: Lub khob hliav qab feem ntau siv tom qab aluminium melting rauv los tswj cov kua dej txhuas.Nyob rau hauv cov txheej txheem kub saum toj kawg nkaus casting, nws kuj siv los tiv thaiv cov hlau ua kua dej ua rau tawg.
Cov khoom siv aluminium silicateua lub luag haujlwm tseem ceeb hauv aluminium alloy casting, muab ntau yam txiaj ntsig uas txhim kho qhov zoo thiab kev ua tau zoo ntawm cov khoom pov thawj zaum kawg.Los ntawm kev hloov kho cov txheej txheem casting, muab thermal rwb thaiv tsev, cov khoom no pab txhawb kom ua tiav cov khoom zoo, zoo nkauj zoo nkauj aluminium castings.
