In-situ silicon carbide whisker toughened iron runner castable and preparation method thereof
The invention discloses an in-situ silicon carbide whisker toughened iron runner castable and a preparation method thereof. The iron runner castable is prepared from the following raw materials in parts by weight: 65-75 parts of electric smelting dense corundum, 10-18 parts of silicon carbide, 4-10 parts of activated aluminum oxide micro powder, 1-2 parts of cement, 2-4 parts of nano silicon dioxide, 1-3 parts of a porous carbon material, 1-2 parts of carbon black, 2-3 parts of metal silicon powder, 1-3 parts of a composite anti-explosion agent, 0.2-0.5 part of an antioxidant, 0.1-0.3 part of a composite water reducing agent and 0.1-0.4 part of a catalyst. Wherein the porous carbon material, the carbon black, the nano silicon dioxide, the metal silicon powder and the catalyst are mixed in advance through ball milling. The obtained in-situ silicon carbide whisker toughened iron runner castable has the characteristics of good oxidation resistance, high temperature erosion resistance, slag iron chemical erosion resistance, good thermal shock resistance, simple process, long service life and the like.
