Low cement castable refers to a castable with a lower amount of cement. The cement dosage of refractory cement castables is generally 15% to 20%, and the cement dosage of low cement castables is about 5%, and some even reduce to 1% to 2%. The purpose of reducing the amount of cement is to improve the fire resistance of the castable.Low cement castable mainly includes three types: high alumina refractory castable, mullite refractory castable, corundum refractory castable.

Features
1.Good thermal shock resistance.
2.Good slag resistance.
3.Good corrosion resistance.

Application
It's mainly used for furnaces of metallurgy industry, heat treatment furnace, furnace of incineration of garbage, recirculating fluidized bed furnace, furnaces of chemical industry and construction industry, also tundish lining, etc.
