Capacity:3000 MT per month
Raw Material:Bauxite
Max Service Temperature:≥1300℃
Product Introduction
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.
Features
1.Good alkali resistance. 2.High strength. 3.Stable structure.
Application
It's mainly used as linings of kiln hood, decomposing furnace, preheater system, pipeline system and other industrial kiln.
