Daim duab siab alumina cib

Special-shaped high alumina brick grade three high alumina brick is a kind of refractory material, the main component of this refractory brick is Al2O3.

Yog tias Al2O3 cov ntsiab lus siab dua 90%, nws hu ua corundum cib. Vim yog cov peev txheej sib txawv, cov qauv hauv tebchaws tsis zoo ib yam. Piv txwv li, Cov tebchaws nyob sab Europe teeb tsa qis qis ntawm Al2O3 cov ntsiab lus rau cov khoom siv alumina siab ntawm 42%. Hauv Suav teb, raws li cov ntsiab lus ntawm Al2O3 hauv qib siab alumina cib, feem ntau nws tau 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%.

Zoo li siab alumina cib

khoom nta

a Refractoriness

Cov refractoriness ntawm cov av alumina siab yog siab dua li cov av nplaum cib thiab cov pob zeb ib nrab silica, mus txog 1750 ~ 1790 ℃, uas yog cov khoom siv hluav taws xob zoo.

b. Thauj qhov kub thiab txias

Vim tias cov khoom lag luam siab alumina muaj Al2O3 siab, tsis muaj qhov tsis huv, thiab tsis muaj lub cev iav fusible, lub nra hnyav ua kom sov siab dua li ntawm cov av nplaum cib. Txawm li cas los xij, vim tias cov mullite muaju tsis tsim cov qauv network, lub ntsuas kub ua kom sov tseem tsis siab li cov cib silica.

c. Slag tsis kam

Cov av alumina siab muaj ntau dua Al2O3, uas yog ze rau cov khoom siv hluav taws xob nruab nrab, thiab tuaj yeem tiv taus kev yaig ntawm cov kua qaub slag thiab cov tshuaj alkaline. Vim tias suav nrog SiO2, lub peev xwm los tiv thaiv alkaline slag tsis muaj zog dua li cov kua qaub slag.

Khoom Siv Pab

Feem ntau yog siv rau sab hauv ntawm lub qhov cub tawg, lub qhov cub tawg tawg, hluav taws xob saum lub qhov cub, lub qhov cub tawg, lub qhov cub tawg rov qab, thiab lub qhov cub tawg. Tsis tas li ntawd, cov cib alumina siab kuj tseem siv dav ua qhib cov khoom siv rov ua kom zoo dua qub, cov ntsaws rau cov tshuab, cov cib nozzle, thiab lwm yam. siab alumina cib qhov twg av nplaum cib tuaj yeem ua tau raws li qhov xav tau.
