55% 65% 75% Al2O3 High Alumina Castable Refractory Mortar for high-Al fire bricks masonry

Castable Refractory Mortar used for firebrick is made of bulk refractory, which should have good masonry performance and high temperature performance, so that can bond firebrick into dense integral furnace lining.

Castable Refractory mortar should be chosen with consideration of the close chemical composition of firebrick to ensure that the masonry can bond reliably.

Also the mortar’s sintering temperature is or slightly lower than the parts of the working temperature so that the mortar can be sintered under operating conditions, and bond with refractory brick, but should not lower too much, so that the refractory performance can not adapt to the requirement of masonry.

 

High alumina refractory mortar is soft clay or chemical binder as the main materials. Al2O3 content is determined according to masonry composition and usage requirements of masonry parts.

High alumina refractory mortar is widely used in various industrial kilns with high alumina brick masonry. Mainly used in the bottom of blast furnace and upper parts of hot blast stove.

 

High Alumina Castable Refractory Mortar with features of:

The quality of masonry that has good liquidity and plastic performance

Certain water retention performance

Sufficient fire resistance,

Small dry shrinkage, no cracking at high temperature

Anti-slag corrosion

Low apparent porosity and permeability, and good air tightness

Enough adhesive strength to combine masonry into a solid whole at the working temperature

The thermal expansion coefficient is consistent with the firebrick, and different types of refractory               mortars are selected for different masonry
