Dry ramming mass for induction furnace lining
Classification:
Product Introduction
The product is composed of high-purity corundum and magnesia in a specific ratio. The special mixing process ensures the uniform structure and stable performance of the material. In the process of use, the surface of the material is reacted and sintered to form a dense corundum spinel layer, which gives the material high resistance to erosion and excellent resistance to molten steel penetration. The back of the dense layer is an unreacted loose layer, which can effectively absorb the stress of thermal shock production and give the material high resistance to thermal spalling.
