The invention discloses a corundum dry ramming material for an intermediate frequency induction furnace and a preparation method thereof, and relates to the technical field of refractory materials for an intermediate frequency induction furnace. The corundum dry ramming material of the present invention comprises the following raw materials by weight: 48-58% fused corundum, 20-40% tabular corundum, 6-16% fused magnesia, 0.5-1.5% yttrium oxide fine powder, 0.5 ‑1.0% titanium dioxide fine powder, 0.5‑2.0% ZrO 2 ‑SiC fine powder, 0.5‑1.0% nickel oxide fine powder, 5‑10% additive. In the present application, fused corundum, tabular corundum, and fused magnesia are used as aggregates, yttrium oxide fine powder, titanium dioxide fine powder, ZrO2-SiC fine powder, and nickel oxide fine powder are used as powder materials, and additives are added to prepare a kind of Ramming material with high refractoriness, good volume stability, high temperature strength, excellent erosion resistance and excellent erosion resistance. |
