Kev siv cov ntaub ntawv refractory nyob rau hauv qhov chaw kub kub ntawm lub qhov cub yuav tsum ua raws li cov yam ntxwv ntawm kev ua haujlwm me me ntawm cov kiln thiab ua raws li cov khoom raug rho tawm haujlwm.
Siv cov av nplaum refractory cib ntawm qhov kub hauv qab 1300 degree
High alumina cib yog siv ntawm 1300 degree -1400 degree .
Siv silica cib ntawm 1400 degree -1500 degree .
Magnesia-alumina cib yog siv ntawm 1500 degree -1600 degree .
Siv corundum cib hauv qab 1800 degree.
Cov yam ntxwv ntawm lub siab alumina cib siv nyob rau hauv qhov chaw kub kub ntawm qhov chaw kilns:
1. Zoo thermal stability.
2. High refractoriness thiab load softening kub;
3. Muab faib ua cov qauv zoo, hom tshwj xeeb zoo sib xws, cov duab tshwj xeeb thiab cov cib tshwj xeeb.
