Nyob rau hauv lub yim hli ntuj, kub muag, 50 tons Andalusite yog packed rau xa mus rau peb cov neeg muas zaub nyob rau hauv Thaib teb.High zoo siab alumina cib nrog zoo packing.
"JUCOS REFRACTORY" - Koj qhov kev ntseeg siab ntawm cov khoom lag luam Refractory.
Raws li kev pom ntawm nws lub cev thiab tshuaj lom neeg, nws yog ib qho ntawm cov khoom siv refractory paub zoo. Ntxiv rau kev siv los ua cov ntaub ntawv qib siab refractory rau kev lag luam smelting, thiab cov khoom siv raw rau kev lag luam ceramic. Nws kuj tseem tuaj yeem siv los ua kom lub zog siab lub zog silicon-aluminium alloys los tsim cov hlau fibers thiab cov lus qhia-hom supersonic aircraft thiab spacecraft. Raws li cov lus ceeb toom, mullite tseem siv txawv teb chaws los ua kom cov thee thiab ua radomes. Qee tus ntawm lawv zoo-crystalized thiab ci xim thiab tuaj yeem siv los ua khoom siv tes ua thiab kho kom zoo nkauj. Txij li thaum xyoo 1970, nws tau txais txiaj ntsig los ntawm Tuam Tshoj txoj kev tsim khoom lag luam, thiab nws cov chaw thov kuj tseem nthuav dav. Lub mullite tsim tom qab calcination muaj siab refractoriness, tshuaj stability thiab mechanical zog, yog li nws yog dav siv nyob rau hauv metallurgy, tsev cov ntaub ntawv thiab lwm yam sectors.
Raws li refractory
Qhov no muaj txiaj ntsig tshwj xeeb rau kev txhim kho kev ua haujlwm kub thiab lwm yam txheej txheem metallurgical. Unshaped refractory yog siv ncaj qha yam tsis muaj hluav taws xob, uas tuaj yeem txuag hluav taws xob, thiab nws qhov ntim ruaj khov ntawm qhov kub thiab txias yuav muaj kev cuam tshuam zoo rau nws lub neej kev pabcuam. Nyob rau hauv kev xyaum ntawm Yuqi refractories, yog hais tias tus raug rho tawm kev txhaj tshuaj thiab yas siv raws li qhov kev faib ua feem, lawv yuav muaj ib tug npaum li cas ntawm av nplaum thiab inorganic binders, uas yuav ua rau lub unshaped refractories ntsws thaum lub sij hawm kub thiab txias txheej txheem, tawg, peeling, thiab shortening. Lub neej ua haujlwm ntawm cov khoom siv refractory. Txhawm rau tswj thiab txo qhov shrinkage ntawm refractory khoom nyob rau hauv lub sij hawm ntev kub, yog hais tias ib tug tej yam nqi ntawm andalusite yog ntxiv rau cov khoom xyaw thiab cov expansion thiab stability cov yam ntxwv, cov saum toj no-hais me me shrinkage tshwm sim ntawm cov khoom amorphous tuaj yeem. raug tshem tawm, thiab lub neej kev pabcuam ntawm cov khoom siv tuaj yeem txuas ntxiv mus txog tsib xyoos ntev li ntev tau.
Refractory cib
Andalusite yog calcined los ua cov ntaub ntawv, uas tuaj yeem siv rau hauv qhov tseem ceeb xws li cov qhov cub kub kub, lub qhov cub kub kub, thiab rov ua kom sov. Nws kuj tseem siv tau rau ntau yam kev pab cuam casting thiab cov cuab yeej ua haujlwm, thiab tseem tuaj yeem siv los ua cov khoom siv hauv tsev, kub kub aluminosilicate insulators, thiab cov xuab zeb molding fabrics. Siv cov refractory fiber ntau ua los ntawm nws ua rau lub tshuab hluav taws xob tuaj yeem txuag hluav taws xob los ntawm 30-50 feem pua piv nrog cov av refractory los yog lub teeb ci ci hauv ob sab phlu. Ntxiv nrog rau kev txo cov roj noj thiab ua kom ruaj khov, lub cib refractory no tseem tuaj yeem txuag tau ntau dua 40 feem pua ntawm kev noj cov khoom siv refractory.
Cov khoom siv raw rau kev tsim cov silicon-aluminium alloy, alumina thiab aluminium hlau: Vim tias cov ntsiab lus siab ntawm andalusite Al2O3 thiab cov ntsiab lus qis ntawm oxides xws li hlau, titanium thiab calcium, nws tsis tas yuav siv alumina thaum siv los tsim silicon- aluminium alloy nrog 60 feem pua ntawm txhuas. Nws tuaj yeem ua kom yooj yim cov txheej txheem ntau lawm thiab txhim kho kev tsim khoom.
