Anti-erosion oxidizing agent for refractory material and preparation method thereof
The invention discloses an anti-erosion oxidizing agent for a refractory material. The anti-erosion oxidizing agent is formed by mixing the following raw materials, by weight, 80-95% of silicon carbide micro-powder, 0-10% of alumina micro-powder, 0-10% of borate and 1-5% of sodium polyacrylat. A preparation method of the anti-erosion oxidizing agent comprises the following steps: (1) co-grinding silicon carbide micro-powder, alumina micro-powder, borate and sodium polyacrylat, adding water and stirring to obtain uniform slurry with solid content being 75-85% and the temperature being 60-70 DEG C; and (2) drying the above uniform slurry so as to obtain an a powdery anti-erosion oxidizing agent with water content being less than 3%. The anti-erosion oxidizing agent has a good oxidation resistant effect on all carbon-containing refractory products. The antioxidation temperature of the anti-erosion oxidizing agent can be as low as 500 DEG C. Anti-erosion performance of a carbon-containing refractory material also can be raised, and the anti-erosion oxidizing agent has good resistance to erosion of molten iron, acid and basic slag.
