The kiln roof is prone to damage, especially in the stage of putting into operation the ignition kiln, For this reason, the refractory material for the top of the tunnel kiln must be carefully selected
The general ingredients of acid-resistant refractory castables are acid-resistant refractory aggregate 60%-70%, powder 30%-40%, and water glass solution with an external density of 1 38-1 42g cm3 13%-16%
At present, the main types of refractory linings used in glass kilns are fused mullite bricks, fused zirconia corundum bricks, fused chromium zirconium corundum bricks, fused quartz bricks, fused corundum bricks, and so on
Zircon bricks for glass kiln use zircon as the main raw material, adding binders and additives, Zircon bricks are classified into the high-density type and dense type according to production technology and physical and chemical indicators
Refractories are industrial high-temperature materials that are essential for normal production in industries, we will combine customer cases to learn about several refractory material indicators that are often confused by people
After comparative analysis and observation of the use of magnesia carbon refractory materials and alumina-magnesia-carbon refractories, it is found that the following conditions all illustrate the superiority of magnesia-carbon refractories as refractory lining materials for ladle walls
The preheating zone and cooling zone of the double-chamber lime vertical treasure are mostly built with clay bricks, the calcining zone is built with magnesia chrome bricks or magnesia bricks, and part of the preheating zone and the cooling zone is built with magnesia refractory bricks
Steel fiber castable for the aluminum melting furnace In the heat-insulating refractory castable, if inorganic fiber is added, it can not only enhance the toughness but also help to improve its heat insulation performance
