Alkali Resistant Castable

  • Alkali Resistant Castable

Product Description And Parameters

Application:Cement and lime Kiln, or other industrial kilns.

Raw Material:Bauxite

Max Service Temperature:≥1300℃

Capacity:3000 MT per month

Alkali resistant castable has good high temperature performance and alkali corrosion resistance.It can form a glaze layer on the surface of the material in a high temperature state to prevent the penetration of alkaline material, thereby playing an alkali resistant effect.

1.Good alkali resistance.
2.High strength.
3.Stable structure.

It's mainly used as linings of kiln hood, decomposing furnace, preheater system, pipeline system and other industrial kiln.
