Product Description:

High-alumina refractory mortar is primarily made from high-alumina clinker, with binders consisting of soft clay or chemical binders. The Al2O3 content is determined based on the composition of the bricks and the usage requirements of the砌筑部位. The high-alumina refractory mortar is divided into 8 grades according to Al2O3 content and bonding strength. Standard high-alumina refractory mortar includes 3 grades: LN-55A, LN-65A, and LN-75A, while phosphate-bonded high-alumina refractory mortar includes 5 grades: LN-55A, LN-65B, LN-75B, LN-85B, and GN85B.

Product Applications:

Broadly used in the construction of various industrial kilns with high-alumina bricks. Such as for building the roof, regenerative chamber, combustion chamber, etc., on hot blast stoves, and for the upper sections of blast furnace shells. Additionally, it can be used for repairing the roofs and walls of industrial kilns.
