Corundum ramming material:
This product uses high-quality high-aluminum, corundum, spinel, fused high-purity reburned magnesia as the main raw materials, adds various binders special properties of micronized magnesia-calcium synthetic sand materials. Mixed. This series of products are high-grade aluminum-rich spinel refractory materials. The material is neutral weakly alkaline. It is suitable for all kinds of carbon steel, low manganese steel, alloy steel, alloy cast iron, high-speed tool steel stainless steel.
Main chemical composition: AL2O370-92% MGO 7-20%, particle size: 0-5MM, bulk density: 2.75-3.0g/cm3, temperature range: 1700℃-1800℃.
Ramming material refers to an unshaped refractory that is constructed by ramming (manual mechanical) hardened under heating above normal temperature. It is made by mixing refractory aggregates, powders, binders, admixtures with water other liquids with a certain gradation.
According to the material classification, there are high alumina, clay, magnesia, dolomite, zirconium silicon carbide-carbon refractory ramming materials.
