Alumina SIC Cib
Kev piav qhia
Alumina SIC Brick yog cov khoom siv refractory ua haujlwm siab, feem ntau yog ua los ntawm alumina (Al2O3) thiab silicon carbide (SiC) ua cov khoom tseem ceeb, ua ke nrog lwm cov khoom siv raw khoom.
Nta
1.High kub kuj:
Alumina SIC Cib tuaj yeem nyob ruaj khov nyob rau hauv qhov chaw kub kub siab tshaj 1600 degree yam tsis muaj softening lossis deforming, ua rau lawv tsim nyog rau qhov chaw ua haujlwm kub heev.
2.High lub zog thiab tiv thaiv hnav cov khoom:
Qhov sib ntxiv ntawm silicon carbide ua rau cov cib muaj qhov tawv tawv thiab hnav tsis kam, thiab tuaj yeem tiv taus cov neeg kho tshuab hnav ntawm qhov kub thiab txias.
3.Thermal shock resistance:
Nws muaj cov thermal poob siab zoo heev thiab tuaj yeem tiv taus qhov kub hloov pauv sai yam tsis muaj kev tawg lossis puas tsuaj.
4.Antioxidant zog:
Cov tshuaj ruaj khov ntawm silicon carbide thiab aluminium oxide muab cov cib zoo los tiv thaiv oxidation thiab tseem nyob ruaj khov txawm tias nyob hauv oxidizing cua.
5.Chemical tsis kam:
Nws muaj zog tiv taus acidic thiab alkaline slag thiab hlau kua, thiab yog haum rau corrosive ib puag ncig.

Txheej txheem ntau lawm
1.Raw khoom npaj: Xaiv high-purity alumina hmoov thiab silicon carbide hmoov ua cov ntaub ntawv tseem ceeb.
2.Cov khoom xyaw thiab kev sib xyaw: Sib tov alumina hmoov thiab silicon carbide hmoov nyob rau hauv ib qho kev faib ua feem, thiab ntxiv cov nqi tsim nyog ntawm binders thiab additives los txhim kho kev ua tau zoo ntawm cov cib.
3.forming: Cov sib tov yog loaded rau hauv pwm thiab ua rau hauv cib los ntawm qhuav nias, isostatic nias los yog extrusion.
4.dry: Cov cib tsim tau qhuav kom tshem tawm cov dej noo ntau dhau. Cov txheej txheem ziab yuav tsum zoo ib yam kom tsis txhob tawg ntawm cov cib.
5.sintering: Cov txheej txheem sintering yog nqa tawm hauv qhov kub kub, feem ntau ntawm qhov kub ntawm 1500 degree txog 1800 degree, kom ntseeg tau tias qhov ntom thiab ruaj khov ntawm Alumina SIC Brick.
6.cool down: Tom qab sintering, cov cib yuav tsum tau maj mam txias kom tsis txhob tawg thiab deformation tshwm sim los ntawm cua txias thiab cua kub ceev.
7. Kev soj ntsuam zoo: Ua kev soj ntsuam zoo ntawm sintered aluminium silicon carbide cib, nrog rau kev tshuaj xyuas zoo, ntsuas qhov ntev, thiab kev ntsuas lub cev (xws li lub zog compressive, abrasion resistance, thermal shock stability, thiab lwm yam).
Cov khoom siv
Alumina SIC Cib txuas ntxiv tsim cov txheej txheem tiv thaiv thaum siv, tsis txhob tev lossis tawg, thiab lawv lub neej kev pab cuam txuas ntxiv. Nws yog dav siv nyob rau hauv lub kiln tawm, kev nyab xeeb cheeb tsam thiab sab qaum teb hloov chaw, thiab yog qhov zoo tshaj plaws kev xaiv rau alumina bricks nyob rau hauv teb kilns.
