Product Details
Product Description
The raw material for producing this kind of bricks is electrically fused magnesiachrome clinker. The bricks are manufactured by high pressure moulding and high temperature burning and have even microstructures and coarse periclase crystals. Their direct bonded degree is high. They have high corrosion resistance and erosion resistance and are applied in the equipment of VOD, AOD, RH for secondary steelmaking and at the key locations of copper flash furnaces.
