P80 series high alumina castable Product Features: 1, the product of phosphate to form a three-dimensional network-like structure at high temperatures, it has a high temperature strength, the temperature does not decrease the strength characteristics, enhanced wear resistance at high temperature castable loss of performance. Improve the high temperature hot strength, so castable corrosion resistance and enhanced anti-ablation. 2, good thermal shock resistance due to the use of phosphate as a binding agent, fewer impurities within the material, when rapid temperature changes, the volume of small stress, thermal shock resistance of refractories has been significantly improved. More suitable for large kiln construction and repair, repairing, no baking, are durable, greatly shorten the construction period. Suitable for dry cement kilns around the kilns, kiln door cover, cooler, tertiary air duct, calciner and other parts.
