Menene kayan da aka hana amfani da su a cikin tanderun masana’antu na aluminium?

Abubuwan da ke hanawa don tanderun masana’antu na aluminium galibi bulo ne masu ƙanƙantar da kai, amma zaɓin ya bambanta ƙwarai gwargwadon sassa daban -daban. Refractories for aluminum masana’antu tanderu bukatar a yi high sintering ƙarfi, kananan rami diamita, low abun ciki na SiO2, Na2O, kuma K2O. Har ila yau, rufin tanderun yakamata ya sami kyakkyawan aikin yin ɓarna a zazzabi na 800 ° C. Editan Kerui Refractories ya tattara kayan ƙuntatawa na yau da kullun don tanderun masana’antu na aluminium don bayanin ku kawai.

An rufe murfin murfin ɗumbin murhun murhun murfin murfin murfin murfin murfin murfin murfin harsashi, sannan an gina shi da ƙasa mai diatomaceous, tubalin beads mai yawo ko tubalin yumbu mai yumɓu, kuma wasu daga cikinsu yanzu an maye gurbinsu da ƙyalli mai ƙyalli. An gina rufin aiki na yankin preheating tare da tubalin yumɓu, kuma ana amfani da manyan tubalin alumina ko phosphate-bonded high-alumina for the high calcination zone.

A halin yanzu, an yi amfani da ƙirar da ba a tsara ta ba a masana’antar aluminium, kamar ƙaramin allurar aluminate-haɗe-haɗe mai ƙyalƙyali a cikin yankin ƙira, da fiber ɗin ƙarfe ya ƙarfafa ƙarfe mai jurewa don ƙunan baki, murhun murhu, da wutsiyoyi.

Fushin walƙiya shine shigar da ƙusoshin angin ƙarfe mai jure zafi ko angaram ɗin yumbu a kan harsashin wutar makera, sannan a shimfiɗa wani farantin 20mm mai kauri mai kauri, kuma a ƙarshe ya zubar da katanga mai kauri 200-300.

Rufin aiki na murhun murhun murhun murhun wuta na aluminium a cikin hulɗa da narkakken aluminium gabaɗaya an gina shi da manyan tubalin alumina tare da abun Al2O3 na 80-85%; lokacin da ake narkar da ƙarfe na ƙarfe mai ƙyalli, ana amfani da tubalin mullite ko tubalin corundum. A kan gangaren murhu, shigar da aluminium sharar gida da sauran sassa masu sauƙin lalacewa da sawa, kuma yi amfani da nitride na silicon don haɗawa da tubalin nitride na silicon. Gilashin aluminium masu gudana da kantunan aluminium sun lalace ta hanyar zubin aluminum. Gabaɗaya, ana amfani da haɗin kai ko silicon nitride silicon carbide tubalin, kuma ana amfani da tubalin zircon azaman kayan haɗin gwiwa. Rufin tanderu wanda baya tuntuɓar narkakken aluminium gabaɗaya yana amfani da tubalin yumɓu, ƙyallen ƙyallen yumɓu ko filastik mai jujjuyawa.

Abubuwan shigar da murhun murhu don ƙona aluminium da aluminium galibi kayan bushewa ne na aluminium, ko carbide na siliki a cikin kayan bushewar alumina, wanda ba shi da haɗari ga zubar ruwa.
