High Alumina Refractory Mortar

Name:	High Alumina Refractory Mortar

Refractory mortar is an auxiliary product of refractory brick construction and furnace wall, mainly including fire clay refractory mortar, high alumina refractory mortar, siliceous refractory mortar,magnesia refractory mortar,etc.The kind of refractory brick you use determines the kind of refractory mortar you should choose.

Product Description

The main material of high alumina refractory mortar is high chamotte, the binding agent is soft clay or chemical bond. The content of Al2O3 is determined by the brick composition and using request of construction part. It can be widely used in all kinds of industry furnaces built with high alumina bricks, such as the construction of furnace roof, regenerative chamber, combustion chamber and other parts of hot-blast furnace, upper part and other parts of blast furnace, the repair of furnace top, furnace wall and other parts of industrial furnaces.
According to the content of Al2O3, high alumina refractory mortar can be divided into four types, 75, 70, 60, and 50. It is the auxiliary product for the construction of high alumina bricks. The refractoriness is 1750~1790℃, loss on ignition should be ≤5%.
