Andalusite Cib

Andalusite cib yog ua los ntawm kaolin, serpentine thiab lwm yam ntaub ntawv refractory ua cov ntaub ntawv tseem ceeb, uas yog tov, molded thiab raug rho tawm haujlwm ntawm qhov kub thiab txias. Lub ntsiab ntau yam muaj xws li banshangshi andalusite refractory cib, chav kawm hluav taws kub-txiav thiabalusite refractory cib, banshang andalusite refractory cib, lub kaum sab xis rotation andalusite refractory cib, 1900 chav kawm andalusite refractory cib rau boilers, thiab lwm yam.

Andalusite cib feem ntau muaj qhov tsawg thermal expansion tus nqi thaum lub sij hawm hloov dua siab tshiab, thiab muaj ob hom, ib tug yog raug rho tawm haujlwm andalusite refractory bricks, thiab lwm yam yog unfired andalusite refractory cib.

Andalusite refractory bricks siv corundum, andalusite ua cov ntaub ntawv tseem ceeb thiab nruj me ntsis tswj cov particle loj ntawm cov ntaub ntawv raw. Nws txais cov txheej txheem tshiab, txais cov khoom xyaw ntau theem, matrix homogenization, thiab txiav txim siab qhov zoo tshaj plaws calcination kub, thiab lwm yam, thiab muaj kev ua tau zoo heev andalusite cib. Nws tuaj yeem ua tau raws li qhov sib txawv ntawm qhov sib txawv ntawm qhov cub tawg thiab qhov cub kub kub thiab qhov chaw ua haujlwm sib txawv

Khoom Parameter:

1.Bulk ceev: Ntau dua lossis sib npaug li 2.3g / cm³

2. Compressive zog: ntau dua los yog sib npaug rau 40MPa

3.Refractoriness: Ntau dua lossis sib npaug ntawm 1750 degree

4. Thermal conductivity: Tsawg dua los yog sib npaug rau 1.3W / (m·K)

5. Nyhav: 2.6kg / thooj

Andalusite refractory cib yuav hloov mus rau hauv mullite los ntawm cua sov, thiab tom qab hloov dua siab tshiab, lawv yuav muaj hluav taws ntau dua. Lub refractoriness tuaj yeem ncav cuag siab tshaj 1800 degree, thiab andalusite cib muaj ob peb impurities, thiab kub kub lub zog txo qis heev. Nws kuj tseem tiv taus txias txias thiab kub ceev, siab txhua yam muaj zog, muaj zog thermal poob siab tsis kam, muaj zog slag tsis kam, siab load conversion point, thiab muaj tshuaj lom neeg ruaj khov heev (txawm tias insoluble hauv hydrofluoric acid) thiab muaj zog tiv taus tshuaj lom neeg corrosion.

Andalusite yog siv rau hauv kev lag luam feem ntau rau nws qhov kub thiab txias. Tom qab andalusite yog rhuab mus rau 1350 degree nyob rau hauv ib txwm siab, nws pib hloov mus rau hauv acicular mullite. Mullite crystals yog tib daim ntawv ruaj khov ntawm aluminosilicate nyob rau hauv qhov kev txiav txim siab kub.

Thaum lub sij hawm tsim khoom, daim ntawv thov ntawm andalusite raw cov ntaub ntawv kuj tseem ceeb heev. Txhawm rau tiv thaiv cov khoom los ntawm kev poob qis ntawm qhov kub thiab txias, qee qhov nyiaj ntawm andalusite yog ntxiv thaum lub sij hawm batching kom andalusite tshwm ruaj khov nyob rau hauv ntim ntawm qhov kub thiab txias.
Thaum siv andalusite, xws li kev soj ntsuam tas li ntawm cov hlau ladle, nws tuaj yeem tiv taus qhov txias heev thiab kub kub hloov pauv. Tshwj xeeb tshaj yog thaum nws nkag mus rau hauv cov hlau molten, nws tuaj yeem tiv thaiv cov kab nrib pleb thiab tev. Xyuas kom meej tias lub ntim ruaj khov thaum siv thiab txhim kho kev ua tau zoo ntawm qhov tsis yog shrinkage.

Andalusite cib tuaj yeem siv rau hauv cov khoom tseem ceeb xws li kub kub qhov cub thiab kub moj tej tawg yees, nrog rau ntau yam auxiliary pouring thiab kev khiav hauj lwm cov cuab yeej, thiab kuj yuav siv tau los ua rau lub cub tawg, high-temperature aluminosilicate insulators, thiab xuab zeb molding fabrics.

Vim andalusite refractory bricks muaj qhov kub thiab txias, acid thiab alkali tsis kam, thermal conductivity thiab lwm yam zoo, lawv tau dav siv hauv steel, tshuaj, kev tsim kho thiab lwm yam lag luam. Piv txwv li, hauv cov nroj tsuag steel thiab aluminium nroj tsuag, nws yog siv los ua cov khoom siv rau cov phab ntsa ntawm cov khoom siv kub kub thiab cov qauv ntawm lub cub tawg;
Hauv petrochemical, thee chemical thiab lwm yam kev lag luam, nws yog siv los ua cov hauv ob sab phlu thiab qhov cub ntawm reactors, furnaces, hydrogenation catalytic cais tshuab thiab lwm yam khoom siv;
Andalusite refractory bricks kuj tau dav siv nyob rau hauv ntau yam boilers, kho cua sov rauv thiab lwm yam khoom siv, ua ib tug indispensable tsev cov ntaub ntawv nyob rau hauv cov kev lag luam.
