Refractory material for vacuum induction furnace lining
The invention relates to a refractory material for a vacuum induction furnace lining. The refractory material consists of the following components in parts by weight: 60-80 parts of fused white corundum, 10-25 parts of fused magnesite, 5-15 parts of alpha-Al2O3 powder and 3-7 parts of a binding agent, wherein the binding agent is one or two of boric acid and dye-level chromium oxide green; the fused white corundum consists of the fused white corundum with the following granularity in parts by weight: 20-30 parts of fused white corundum with granularity of 6-3mm, 15-25 of fused white corundum with granularity of 3-1mm, 15-25 of fused white corundum with granularity of 1-0mm, and 5-15 parts of fine powder with granularity of 200 meshes; the fused magnesite consists of the fused magnesite with the following granularity in parts by weight: 3-15 parts of fused magnesite with granularity of 6-3mm, 5-15 of fused magnesite with granularity of 3-1mm, and 5-15 of fused magnesite with granularity of 1-0mm; the granularity of the alpha-Al2O3 powder is 325 meshes. The refractory material for the vacuum induction furnace lining disclosed by the invention is remarkably improved in anti-erosion ability, good in thermal shock resistance and slag resistance, so that erosion to a crucible is reduced and anti-stripping times are greatly increased. The product has the characteristics of being stable and reliable in quality, good in performance and long in service life.
