DESCRIPTION
Ramming material is also called furnace lining material, knotting material, iron ditch ramming material. The iron hook ramming material (high-aluminum-silicon carbide-carbon ramming material) produced by our factory uses high alumina bauxite, brown corundum and silicon carbide as the main raw materials, and resin as the binder. It has the characteristics of high bulk density, good medium to high strength, strong corrosion resistance, erosion resistance, non-stick iron slag, and convenient construction. And it does not smoke during use and has a long service life. It can meet the production needs of large, medium and small blast furnaces and submerged arc furnaces.
