Mullite Xuab zeb
Cov ntaub ntawv khoom
Mullite xuab zebyog cov khoom siv aluminium silicate refractory, feem ntau siv hauv stainless hlau precision casting txheej txheem. Lub refractoriness yog hais txog 1750 degrees. Qhov siab dua cov ntsiab lus ntawm aluminium hauv mullite xuab zeb, qhov qis ntawm cov ntsiab lus hlau, thiab cov hmoov av me dua, qhov zoo dua ntawm cov khoom ntawm mullite xuab zeb. Mullite xuab zeb yog tsim los ntawm high-temperature sintering ntawm kaolin.
Nta:
1. Siab melting point, feem ntau ntawm 1750 thiab 1860 ° C.
2. Zoo siab kub stability.
3. Tsawg thermal expansion coefficient.
4. Muaj tshuaj lom neeg ruaj khov.
5. Tsim nyog particle loj faib tso cai rau xaiv thiab hloov raws li qhov sib txawv casting txheej txheem thiab casting yuav tsum tau.

Daim ntawv thov
Lub hauv paus ntawm precision casting yog pwm plhaub tsim (tus txheej txheem ntawm txheej txheej cov quav ciab qauv nrog ntau txheej ntawm cov khoom siv refractory los tsim ib lub plhaub sab nrauv. Tom qab cov qauv siv quav ciab melts, kab noj hniav yog tsim rau pouring molten hlau). Mullite xuab zeb feem ntau yog siv los ua refractory aggregate nyob rau hauv pwm plhaub thiab siv rau ntau txheej ntawm lub plhaub, tshwj xeeb raws li hauv qab no:
1. Nto Plhaub (Txiav txim siab qhov zoo ntawm qhov Casting)
Muaj nuj nqi:Cov txheej txheej saum npoo yog nyob rau hauv kev sib cuag ncaj qha nrog lub casting thiab yuav tsum xyuas kom meej ib tug du nto tiav (tsis txhob roughness thiab pitting) thaum tseem tiv thaiv qhov pib ntawm cov hlau molten.
2. Back Plhaub (Muab tag nrho lub zog thiab ua pa)
Muaj nuj nqi:Lub plhaub sab nraub qaum yog cov txheej txheem ntau txheej sab nraud txheej txheej. Nws txhawb nqa tag nrho lub zog ntawm lub plhaub pwm (tiv thaiv kev deformation lossis kev sib tsoo thaum lub sij hawm nchuav) thaum ua kom muaj kev ua pa (tso pa tawm ntawm cov kab noj hniav thiab tiv thaiv porosity hauv qhov casting).
3. Cov ntawv thov tshwj xeeb rau kev thov siab Castings
High-temperature alloy castings:xws li dav hlau cav cav turbine hniav (kub kub ntawm 1500-1600 ° C), yuav tsum tau lub plhaub pwm kom tiv taus qhov kub thiab txias. Mullite xuab zeb lub siab refractoriness tuaj yeem hloov cov zircon xuab zeb kim dua (melting point 2550 ° C, tab sis kim), ua tau raws li qhov yuav tsum tau ua kom kub kub thaum txo cov nqi.
Rau reactive hlau castings:xws li txhuas alloys thiab magnesium alloys (uas yog heev reactive thiab yooj yim react nrog lub SiO₂ nyob rau hauv quartz xuab zeb los tsim inclusions), mullite xuab zeb cov tshuaj stability yuav txo tau reactivity thiab tiv thaiv cov tsim ntawm "oxidation inclusions" nyob rau hauv lub casting.
Rau loj precision castings:xws li cua turbine gearbox vaj tse (uas tuaj yeem hnyav ob peb tons), lub plhaub pwm yuav tsum muaj zog ntau dua. Cov txheej txheej rov qab tsim los ntawm mullite xuab zeb thiab binder yog lub zog siab, txo qhov kev pheej hmoo ntawm pwm nthuav dav thiab tawg.
4. Kev sib xyaw nrog lwm cov khoom siv hluav taws xob
Hauv kev tsim khoom tiag tiag, mullite xuab zeb feem ntau yog siv ua ke nrog lwm cov ntaub ntawv los txhim kho pwm plhaub kev ua tau zoo:
Kev sib xyaw nrog zircon xuab zeb:zircon xuab zeb yog siv los ua cov txheej txheej saum npoo (kom ntseeg tau tias muaj qhov ua tiav ntau dua) thiab cov xuab zeb mullite raws li txheej txheej rov qab (kom txo cov nqi). Qhov no yog tsim rau cov castings uas tsis tshua muaj siab saum npoo yuav tsum tau, xws li aerospace qhov chaw.
Ua ke nrog quartz xuab zeb:Rau castings nrog qis kub yuav tsum tau (xws li tooj liab alloy, melting point 1083 ℃), nws muaj peev xwm hloov ib nrab quartz xuab zeb thiab siv qhov tsawg expansion ntawm mullite xuab zeb los txo lub plhaub tawg.
