Fused Magnesia Brick
Classification:
Product Introduction
Electrofused magnesium bricks are the main products of alkaline refractories, with electrofused magnesium sand as the main raw material.
Product Details
Electrofused magnesium bricks are the main products of alkaline refractories, with electrofused magnesium sand as the main raw material, formed by high pressure molding and high temperature firing, the products have high refractoriness, thermal conductivity, compressive strength, and loaded softening temperature, and they have good erosion resistance to iron oxides, alkaline slag, and high-calcium fluxes. It is suitable for heat storage room lattice body heat exchanger and other parts of glass industry.
