Magnesia-Iron-Alumina Composite Spinel Bricks — Chrome-Free Refractories for Cement Kiln Burning Zones
Pollution within the cement industry caused by refractory materials is primarily attributed to chromium-bearing refractories. The main pathways for this contamination are twofold: First, during the calcination of cement clinker, the presence of an oxidizing atmosphere and alkaline oxides—combined with Read More …
Advantages of the Physicochemical Properties of Thermal-Insulating Silicon-Corundum Bricks
Silicon-corundum bricks are developed based on the phosphate-bonded brick series; they are manufactured by utilizing higher-quality bauxite with an increased alumina content, incorporating a specific proportion of silicon carbide, and undergoing processes of batch aging, high-pressure molding, and sintering at Read More …
Application Advantages of Magnesia-Aluminum Spinel Bricks for Cement Kilns
Magnesium-aluminum spinel bricks are based on magnesia-alumina spinel ((MgAl2O4 abbreviated as MA)). Alkaline refractory products are made of high-quality high-purity magnesia and Al2O3-containing ore through batching, mixing, billet making, drying, and firing. It is known for its thermal shock resistance Read More …
