CFB boiler anti-corrosion wear-resistant refractory pouring material and preparation method thereof
The invention discloses a CFB boiler anti-corrosion wear-resistant refractory pouring material and a preparation method thereof; the used technical scheme comprises that the preparation method comprises the steps: mixing 70 wt%-85 wt% of white corundum, 6 wt%-12 wt% of a aluminum oxide micro-powder, 5 wt%-10 wt% of spinel and 2 wt%-8 wt% of cement as raw materials, additionally adding raw materials of 0.05 wt%-0.5 wt% of a water reducing agent, 0.1 wt%-0.5 wt% of a silicon micro-powder and 0.1 wt%-1.0 wt% of an anti-explosion fiber, mixing evenly, then additionally adding raw material of 4 wt%-8 wt% of water, pouring and molding, and thus obtaining the anti-corrosion wear-resistant refractory pouring material. The prepared CFB boiler anti-corrosion wear-resistant refractory pouring material has good corrosion resistance, good wear resistance, good thermal shock stability, and high compression strength.
