Mullite Sand
Amakuru y'ibicuruzwa
Umucangani aluminium silikatike yamashanyarazi, isanzwe ikoreshwa muburyo bwo guta ibyuma. Kuvunika ni dogere 1750. Iyo hejuru ya aluminiyumu iri mu mucanga wa mullite, igabanya ibyuma, kandi umukungugu muto, niko ubuziranenge bwibicuruzwa bya mullite. Umusenyi wa Mullite ukorwa nubushyuhe bwo hejuru bwa kaolin.
Ibiranga:
1. Ahantu ho gushonga cyane, muri rusange hagati ya 1750 na 1860 ° C.
2. Ubushyuhe bwiza bwo hejuru.
3. Coefficient yo kwagura ubushyuhe buke.
4.
5. Gukwirakwiza ingano yingirakamaro yingirakamaro itanga guhitamo no guhinduka hashingiwe kubikorwa bitandukanye byo gukina hamwe nibisabwa.

Porogaramu
Intandaro yo gutondeka neza ni ugukora ibishishwa (inzira yo gutwikira ibishashara hamwe nibice byinshi byibikoresho byangiritse kugirango habeho igikonoshwa cyo hanze. Nyuma yikigereranyo cyibishashara kimaze gushonga, havuka umwobo wo gusuka ibyuma bishongeshejwe). Umusenyi wa Mullite ukoreshwa cyane cyane nkurunani rwogusenyera mugikonoshwa kandi ugashyirwa mubice bitandukanye byigikonoshwa, kuburyo bukurikira:
1. Igikonoshwa cy'Ubuso (Kugaragaza mu buryo butaziguye Ubwiza bw'Ubuso bwa Casting)
Imikorere:Ubuso bwubuso burahuza neza na casting kandi bugomba kwemeza neza kurangiza neza (kwirinda gukomera no gutobora) mugihe nanone birwanya ingaruka zambere zicyuma gishongeshejwe.
2. Igikonoshwa cyinyuma (gitanga imbaraga muri rusange no guhumeka)
Imikorere:Igikonoshwa cyinyuma nuburyo bwinshi butandukanye hanze yubuso. Ifasha imbaraga rusange muri shell ibumba (irinda guhindagurika cyangwa gusenyuka mugihe cyo gusuka) mugihe ihumeka neza (gusohora imyuka iva mu cyuho no kwirinda ubukana muri casting).
3. Impamyabumenyi Zidasanzwe Kubisabwa Byinshi-Bisabwa
Ubushyuhe bwo hejuru cyanenka moteri yindege ya turbine (gusuka ubushyuhe bwa 1500-1600 ° C), bisaba igikonoshwa kugirango ihangane nubushyuhe bukabije. Umucanga mwinshi wa Mullite urashobora gusimbuza umucanga wa zircon uhenze cyane (gushonga 2550 ° C, ariko uhenze), wujuje ibyangombwa byo guhangana nubushyuhe bwo hejuru mugihe ugabanya ibiciro.
Kubyuma bikora:nka aluminiyumu ya aluminiyumu na magnesium alloys (zikora cyane kandi zikora byoroshye na SiO₂ mumusenyi wa quartz kugirango zishyirwemo), imiti yumucanga wa mullite irashobora kugabanya reaction kandi ikabuza gushiraho "okiside okiside" mugukina.
Kubyerekana neza:nk'amazu ya garebox yumuyaga (ushobora gupima toni nyinshi), igikonoshwa gisaba imbaraga zubaka. Igice cyinyuma cyakozwe numusenyi wa mullite na binder nimbaraga nyinshi, bigabanya ibyago byo kwaguka no gusenyuka.
4. Guhuriza hamwe nibindi bikoresho byo kwanga
Mubikorwa nyabyo, umucanga wa mullite ukoreshwa kenshi hamwe nibindi bikoresho kugirango uhindure imikorere yibishishwa:
Gukomatanya n'umucanga wa zircon:umucanga wa zircon ukoreshwa nkurwego rwo hejuru (kugirango urangire hejuru yubuso) hamwe numusenyi wa mullite nkigice cyinyuma (kugabanya ibiciro). Ibi birakwiriye gukina hamwe nibisabwa hejuru cyane, nkibice byindege.
Uhujwe n'umusenyi wa quartz:Kubitera hamwe nubushyuhe buke busabwa (nkumuringa wumuringa, gushonga ingingo 1083 ℃), irashobora gusimbuza igice cyumusenyi wa quartz kandi igakoresha kwaguka gake kumusenyi wa mullite kugirango igabanye ibisasu.
