Corundum refractory castables<\/strong> have a higher aluminum content than other castables<\/a>. Therefore it has higher abrasion resistance and mechanical strength. Speaking of the application of corundum refractory castables, it is mainly used for lining materials of various furnaces such as boilers, blast furnace hot blast stoves, heating furnaces, ceramic kiln and so on. In other words, it is used in parts with more mechanical shock and wear. In addition, this castable is mainly used in thermal equipment such as synthetic ammonia gasification furnaces and carbon black reaction furnaces, and can also be used in repairing furnace linings. RS refractory castable manufacturers<\/a> will introduce you the application of corundum refractory castable. Rongsheng refractory manufacturer’s refractory castable products have guaranteed quality and strong performance.<\/p>\n

The Main Application of High Purity Corundum Refractory Castable<\/h2>\n

High-purity corundum refractory castables are mainly used in large and medium-sized ultra-high power electric furnace cover triangle areas and LF refining ladle covers. It is mainly used to produce breathable bricks and nozzles. It is widely used in the steelmaking industry, and SH benefits and economic benefits are very good.<\/p>\n

High-purity corundum (white corundum, brown corundum) refractory castable<\/a> is an excellent refractory material, mainly used in the working layer of large ladle. It can be pre-made into bricks or can be cast in one piece. The proportion of the latter construction method is increasing. The damage of high-purity corundum refractory castables during use is mainly thermal spalling. However, if microcracks occur in the ladle material used, it will cause the molten steel to penetrate the molten steel during the cooling process, causing the ladle to peel off.<\/p>\n

Corundum Refractory Castable Features<\/h2>\n

High-purity fused white corundum, plate-shaped corundum and dense corundum are used as aggregates, dense corundum and white corundum are used as powders, and appropriate amounts of active SiO2 fine powder and \u03b1-Al2O3 powder are added, and a dispersant and a water reducing agent are added at the same time. With the proper formula and molding process, high-purity corundum refractory castables<\/strong> with a life span equal to or exceeding that of imported similar products can be produced.<\/p>\n

The main component of corundum is \u03b1-Al2O3, which belongs to the triangular crystal system. The crystals are short columnar, the true density is 3.85 ~ 4.01g \/ cm ~ 3, the hardness is 9, and the melting point is about 2050 \u2103. In addition, corundum itself has high thermal conductivity and insulation, good chemical stability and ability to resist reducing agent action. Therefore, corundum can be used as a raw material for advanced refractories. Adding corundum to the refractory castable can make the aluminum content of the castable reach more than 90%, which improves the hardness and strength of the castable. But adding corundum and mullite to the castable, the aluminum content can reach 99%, the hardness, strength and wear resistance can reach a certain range, and the application effect is also significant.<\/p>\n
