Corundum texture casting material
Corundum texture casting material is a high-performance Casting material made of high-quality corundum and using pure calcium aluminate cement as a binder. It has the obvious advantages of high density, high strength, and abrasion resistance. At the same time, the construction operation is simple and convenient. It is widely used in key parts such as the pre-decomposition kiln, the front kiln mouth, and the coal injection pipe of large and medium-sized cement kiln, and has significant effects.
