High -aluminaliab fused alumina: Al₂O₃ Ntau dua lossis sib npaug li 90%, Cr₂O₃ Ntau dua lossis sib npaug li 4% (Al₂O₃ + Cr₂O₃ Ntau dua lossis sib npaug li 95%), qhov ntom ntom Ntau dua lossis sib npaug li 3.70 g / cm³, Fe₂O₃ 1%. Characterized by a red appearance, high density, high alumina and chrome content, and low impurity levels, it offers excellent performance-including high refractoriness, superior compressive strength, good thermal stability, and strong resistance to slag erosion. Nws yog dav siv nyob rau hauv zoo li tus thiab unshaped refractories uas feem ntau siv corundum los yog siab -alumina bauxite-xws li hlau khiav castables, taphole av nplaum, ladle castables, Al{11}}Mg-C bricks, tundish 1{1} zoo li qub, 12} castables, thiab iav rauv refractory cib. Nws tuaj yeem hloov tau ib feem ntawm cov qauv corundum thiab siab -alumina bauxite, txo cov nqi raw khoom los ntawm 10% -30% thaum tuav cov khoom zoo.
Khoom nta ntawm High-Alumina liab fused alumina
1. Tsawg impurity theem:
Tsis muaj cov khoom siv ntxiv tau siv thaum lub sijhawm tsim khoom, kom ntseeg tau tias zoo heev qis-sodium, qis-potassium, thiab qis-calcium specifications; metallic impurity theem yog nruj me ntsis tswj los ntawm kev xaiv chrome ntsuab raw cov ntaub ntawv nrog tsawg hlau impurities.
2. High bulk density:
Thaum tus qauv liab fused alumina feem ntau muaj qhov ceev ntawm ib ncig ntawm 3.5 g / cm³, siab - alumina liab fused alumina nce mus txog 3.7 g / cm³. Qhov siab ceev no ua rau txo cov porosity thiab cov qauv compact, yielding refractories nrog superior zog thiab stability piv rau cov uas ua nrog cov qauv liab fused alumina.
3. Qhov zoo ib yam:
Vim yog cov khoom siv raw khoom nruj, txhua batch ntawm raw cov ntaub ntawv raug nruj, rov kuaj dua kom ntseeg tau tias cov khoom zoo ib yam.
4. Tus nqi -tshwj xeeb zoo rau cov khoom siv corundum ib txwm ua kom cov khoom ua tau zoo:
