Kev piav qhia
High alumina cib yog ib hom refractory, lub ntsiab tivthaiv yog Al2O3. Yog tias Al2O3 cov ntsiab lus siab dua 90%, nws hu ua corundum cib. Vim muaj cov peev txheej sib txawv, cov qauv ntawm cov teb chaws sib txawv tsis sib xws. Piv txwv li, nyob rau hauv cov teb chaws Europe, qhov qis dua ntawm Al2O3 cov ntsiab lus rau siab alumina refractories yog 42%. Hauv Suav teb, Al2O3 cov ntsiab lus hauv siab alumina cib feem ntau muab faib ua peb qib: Qib I - Al2O3 cov ntsiab lus> 75%; Qib II - Al2O3 cov ntsiab lus yog 60-75%; Qib III - Al2O3 cov ntsiab lus yog 48-60%.
Nta:
1.High refractoriness
2.Lub zog kub kub
3.High thermal stability
4.Neutral refractory
5.Zoo tsis kam mus rau acid thiab yooj yim slag corrosion
6.High refractoriness nyob rau hauv load
7.High kub creep kuj
8. Tsawg pom porosity

Daim ntawv thov:
High alumina bricks yog nrov siv rau lub masonry ntawm industrial kilns puab linings, xws li blast furnaces, kub moj tej tawg rauv, hluav taws xob rauv saum, reverberator, teb cement kiln thiab hais txog. Dhau li ntawd, siab alumina bricks kuj tau dav siv los ua regenerative checker cib, stopper ntawm nruam casting system, nozzle cib, thiab lwm yam.
