Sales of high alumina refractory castings

High alumina casting material is an amorphous refractory material, consisting of bauxite clinker (filler), binder and additives. It can be used directly after adding water and stirring, and it is formed by vibration casting method. High aluminum content castings require a certain amount of time to set and cure after production, therefore they need to be cured for a certain period, before they can be dismantled after casting.

How high alumina casting is made?

High alumina castings are produced using traditional ingredients, reducing the amount of cement and adding various additives, thereby improving the performance of the product, increasing temperature strength and load softening temperature, reducing thermal conductivity and allowing high alumina castings to be cast. The thermal stability of the material is better.

Application of high alumina casting material

Refractory castings with high alumina content are suitable for kilns, hot blast blast furnaces, heating stoves, boilers and cement kilns.
