High alumina refractory castable for ladle strong impact resistance convenient construction
The iron ladle high alumina castable is unshaped refractory material with high alumina material as the main raw material and refractory cement as the binder. It is applied to ladle, tank, working layer of integral casting and so on.
It has high strength and refractoriness, and has excellent impact resistance, erosion resistance, penetration resistance wear resistance and other properties.
Long service life, convenient construction and easy maintenance.
It is suitable for all kinds of ladle integral lining, and is an ideal choice of refractory materials for iron ladle.
