High Alumina refractory bricks ua tau zoo nyob rau hauv high-temperature ib puag ncig vim lawv cov cim muaj pes tsawg leeg thiab cov khoom tsim los tiv thaiv huab cua kub. Nov yog cov ntsiab lus tseem ceeb uas ua rau lawv qhov kev ua tau zoo tshaj plaws:
High Alumina Cov ntsiab lus: Alumina cibFeem ntau yog tsim los ntawm high-purity alumina (Al2O3), feem ntau siab dua 50% thiab qee zaum mus txog 99%. Cov ntsiab lus alumina siab no pab lawv ua haujlwm zoo rau qhov kub thiab txias.
Siab Melting Point: Alumina muaj lub siab melting point ntawm ib ncig ntawm 2050 degree (3722 degree F). Cov yam ntxwv no ua kom ntseeg tau tias alumina bricks khaws lawv cov qauv kev ncaj ncees txawm tias nyob rau qhov kub siab heev uas tau ntsib hauv cov txheej txheem kev lag luam.
Thermal stability: Cov cib no muaj qhov zoo tshaj plaws thermal stability, tswj lawv lub zog thiab cov duab nyob rau hauv lub sij hawm raug tshav kub. Lawv tiv thaiv thermal shock tshwm sim los ntawm kev hloov kub ceev, txo qhov kev pheej hmoo ntawm kev tawg lossis tsis ua haujlwm.
Zoo heev Refractoriness: Refractoriness yog hais txog cov khoom muaj peev xwm tiv taus cua sov yam tsis muaj deforming lossis softening. High Alumina refractory bricks nthuav tawm siab refractoriness, ua rau lawv zoo tagnrho rau hauv ob sab phlu, kilns, thiab lwm yam kev siv kub.
Tshuaj tiv thaiv: Alumina refractory bricks muaj kev tiv thaiv zoo rau cov tshuaj yaig thiab tuaj yeem tiv taus cov tshuaj lom neeg hnyav. Cov cuab yeej no ua rau lawv tsim nyog rau kev lag luam uas sib cuag nrog cov tshuaj corrosive ntau.
Tsawg Thermal conductivity: Cov cib no muaj cov thermal conductivity tsawg, txhais tau tias lawv yog cov insulators zoo. Lawv pab txuag cov cua sov hauv ib puag ncig, txhim kho kev siv hluav taws xob hauv kev lag luam.
Ntau yam: Alumina bricks tuaj nyob rau hauv ntau yam compositions thiab qib, muab versatility kom haum txawv kub ntau yam thiab daim ntawv thov yuav tsum tau. Piv txwv li, siab alumina refractory cib, xws li cov uas muaj 70-99% alumina cov ntsiab lus, tshwj xeeb tshaj yog haum rau qhov kub thiab txias ib puag ncig.
Durable thiab kav ntev: Vim lawv cov khoom muaj txiaj ntsig zoo thiab ua haujlwm rau cov cua sov thiab tshuaj, alumina bricks yog ruaj khov, muab lub neej kev pab cuam ntev dua piv rau lwm cov ntaub ntawv refractory.
Nyob rau hauv cov ntsiab lus, qhov tshwj xeeb kev ua tau zoo ntawm siab alumina refractory bricks nyob rau hauv high-temperature ib puag ncig yog ntaus nqi rau lawv cov high alumina cov ntsiab lus, zoo heev thermal stability, refractoriness, tshuaj tsis kam, thiab tag nrho cov durability. Cov khoom no ua rau lawv tseem tsis tau muaj nyob hauv kev lag luam xws li steelmaking, ceramics, iav ntau lawm, thiab lwm yam txheej txheem kub kub.
