Ƙananan creep high alumina tubalin

Ƙananan tubalin alumina mai ƙyalƙyali shine nau’in babban tubalin alumina wanda ya fi tsayayya da babban zafin jiki fiye da sauran samfuran makamantansu, zai iya adana yawan amfani da coke da haɓaka kayan ƙarfe. Rage girman manyan tubalin alumina ya fi na yumɓu na yumɓu da tubalin siliki, ya kai 1750 ~ 1790 ℃, wanda ke cikin kayan haɓaka mai ci gaba. Ƙananan creep da manyan tubalin alumina sun dogara ne akan ka’idar “dutse uku”. Zaɓi bauxite da yumɓu mai haɗewa azaman manyan albarkatun ƙasa, ƙara kyanite da ya dace, andalusite da sillimanite, wanda aka fi sani da “duwatsu uku”, sarrafa alamun jiki da sinadarai da abubuwan barbashi, yi amfani da bauxite + mullite + corundum da sauran albarkatun ƙasa azaman shirin fasaha . A tsarin samarwa, ana fara gano alamomin albarkatun ƙasa da sarrafawa. Bayan murkushewa, fasawa, da tantancewa, ana daidaita sinadaran gwargwadon rabo. Bayan hadawa da nika, ana sarrafa girman barbashi da danshi na laka don biyan bukatun gyare -gyare. Abrasives da suka cancanta zasu iya sarrafa adadin busawa, girma da walƙiya na gyare-gyaren, yayin gwada samfuran da aka gama da ƙima don biyan buƙatun da aka ƙayyade. Tsarin samarwa: yi amfani da babban bauxite calcined super-zazzabi, ƙara kayan zafi mai zafi tare da ƙima mai rarrafe, kuma ana samun babban matsin lamba da ƙima mai zafi. Yana da halayen babban ƙarfi, ƙarancin rarrafe da zafin zafin aiki. An yi amfani da shi sosai a cikin rufin murhu da bulo mai duba manyan tanda masu zafi da tanderu masu zafi.

Samfurin Features:

1. Low creep rate and small high temperature creep.

2. Zazzabi mai laushi yana da girma.

3. Kyakkyawan juriya mai tasiri.

4. Babban zafin jiki da ƙarfin matsawa.

5. Kyakkyawan kwanciyar hankali a babban zafin jiki da juriya mai kyau.

6. Kyakkyawan juriya lalata.

Saboda samfuran bulo masu ƙyalƙyali masu ƙyalli suna da babban Al2O3, ƙarancin ƙazanta da ƙaramin gilashi mai ɗaci, zafin zazzabin da aka ɗora ya fi na tubalin yumɓu, amma saboda lu’ulu’u na mullite ba su samar da tsarin cibiyar sadarwa ba, har yanzu zafin zafin zafin ba shine tubalin siliki ba. babba.

Ƙananan creep da manyan tubalin alumina sun ƙunshi ƙarin Al2O3, wanda ke kusa da kayan ƙin tsaka tsaki, kuma yana iya tsayayya da rushewar acid slag da slag alkaline. Tun da sun ƙunshi SiO2, ikon yin tsayayya da slag na alkaline yana da rauni fiye da na slag acid.

Amfanin Samfur:

Ƙananan tubalin manyan alumina ana yin su da katako na bauxite na musamman a matsayin babban kayan albarkatun ƙasa, ana ƙara su da ƙari na musamman. Bayan samar da matsin lamba da harbe-harben zazzabi mai zafi, suna da fa’idojin babban ƙarfin ajiyar zafi da ƙarancin ragi. Sun dace da ƙananan wuta da matsakaici. Murhun iska mai zafi.

Ana amfani da ƙaramin creep da manyan tubalin alumina don murhun murhu da tanderun wuta mai zafi don tashoshin famfon wutar makera. Tsarin simintin ya karɓi jerin AI2O3-SiC-C. Yana yana da kyawawan halaye na lalata juriya, yashewa juriya da kuma high thermal kwanciyar hankali. Ana iya amfani da shi zuwa babban tashar wutar makera. Hot karfe line, slag line, lilo bututun ƙarfe, saura baƙin ƙarfe tanki, saman babban ramin murfin, bangarorin biyu na babban rami murfin, baƙin ƙarfe rami, slag rami, da dai sauransu Don
