Fused magnesia brick

- Aug 22, 2018 -

The fused magnesia brick has a compact brick structure and high mechanical strength.

It has the advantages of less impurity content, etc. It is mainly used for heat storage dense refractory bricks of large glass kiln. The refractory material has certain shape and size. The weight per unit volume and density are large, indicating that the compactness is good and the strength is high. It is also called high temperature load to start deformation. Temperature, called reheating line change or residual line change, refers to the change of volume expansion and contraction in the same temperature change every time, high temperature resistance, about 1800℃, load softening temperature is 1620-1640℃, thermal expansion coefficient is small.
