High Purity Magnesia Sand Periclase-spinel Refractory Brick
Material indicators: including the content of magnesium O, Al2O3 content, SiO2 content, etc., these indicators reflect the composition of the material.
Physical properties: including bulk density, apparent porosity, normal temperature compressive strength (MPa), load softening temperature, etc., these parameters are directly related to the mechanical properties and service life of the material.
Thermal performance: including thermal shock stability, thermal shock resistance, thermal shock resistance, etc., magnesia-aluminum spinel brick has good thermal shock stability, can withstand multiple water cooling or air cooling alternations. 2
Chemical properties: including the corrosion resistance and linear expansion coefficient of different types of slag, magnesia-aluminum spinel brick has better resistance to alkaline slag and iron oxide slag than other types of spinel brick.
Wear resistance: Spinel bricks should have good wear resistance to adapt to long-term use in industrial kilns such as cement kilns. 3
Thermal conductivity: The smaller the thermal conductivity of spinel bricks, the better, which will help heat conduction and reduce energy loss.
