Product description
Induction furnace alumina ramming mass is a cost-effective dry vibrating refractories composed of special grade clinker clinker, corundum, spinel, magnesia and sintering agent. Such ramming mass is suitable for the melting of carbon steel, alloy steel, stainless steel and high manganese steel, with high service life and high cost performance. Induction furnace alumina ramming mass is used by many foundry companies and steel plants because of achieving low cost and long life with good performance.
Advantages of alumina ramming mass
The induction furnace used alumina ramming mass has a series of advantages such as erosion resistance, strong stability, no cracking, strong operability, and high refractoriness. This series of products are aluminum-magnesium high-grade refractory materials, which are neutral and weakly alkaline.
