Aluminum Magnesium Refractory Castable

      Aluminum magnesium refractory castables are monolithic refractory materials manufactured from high-quality raw materials such as fused magnesia, sintered magnesia–alumina spinel, fused corundum, and high-purity alumina powder through precise formulation and advanced production processes.

      The in-situ formation of the spinel phase significantly enhances the material's resistance to slag erosion and improves its structural stability at high temperatures.

      These castables are widely used in critical components of metallurgical, non-ferrous metal, and other high-temperature industrial furnaces where corrosion resistance and long service life are essential. They are often used in combination with corundum castables, high-alumina castables, and low-cement refractory castables.
 

      To ensure the stable formation of the spinel structure in aluminum magnesium refractory castables under high-temperature conditions, standardized construction procedures should be followed.

      Before construction, ensure that the working environment is dry, the castable is within its shelf life, the formwork is firmly secured, and the anchors are properly installed.

      Strictly control the water addition and mechanically mix the material until a uniform and workable consistency is achieved. During installation, the castable should be poured in layers and properly vibrated to ensure compactness.

      After pouring, allow the lining to cure naturally, followed by gradual drying and baking according to the recommended heating curve.

Relying on extensive experience in the production of spinel castables, Shandong Haixin Refractory Materials strictly controls the magnesium content, material reactivity, and high-temperature formation behavior of aluminum magnesium refractory castables. This ensures the stable formation of a dense spinel structure under actual operating conditions, providing customers with reliable solutions for highly corrosive environments.

Aluminum magnesium refractory castables are mainly used in the following applications:

●Ladle and tundish working linings in the metallurgical industry

●Critical corrosion-prone areas in non-ferrous metal smelting furnaces

●High-temperature reactors and refining equipment

●High-corrosion and high-load zones of industrial furnaces
