Quality Magnesium Aluminum Fused Spinel for Refractories Materials
1. Fused Spinel Introduction
Fused aluminum-magnesium spinel is smelted by adopting high purity powdered magnesium and powdered commercial alumina through large-scale high-temperature electric arc furnace. It is characterized by high density, good appearance and color, strong corrosion resistance, good thermal shock. It is widely used for refractory products, such as steel-making electric furnace roofs, converter and ladle, large cement rotary kiln, and glass regenerator.
We produce Fused aluminum magnesium spinel including magnesium-rich spinel, general spinel and aluminum-rich spinel. Magnesium-rich spinel is mainly used in cement kiln firing zone with periclase spinel brick, over-spinel brick, lithium battery three-way catalysis sag high resistance in alkaline environment; The general spinel is used for corundum spinel castable in ladle, breathable brick, nozzle, furnace lid and other parts; The aluminum-rich spinel, with good alkaline residue and good anti-permeability, is mainly used for high-performance aluminum spinel castable, and the demanding parts that RH spinel brick instead of magnesia-chrome brick.
