Wear-resistant corrosion-resistant refractory material for hazardous waste garbage incinerator and preparation method of wear-resistant corrosion-resistant refractory material
The invention belongs to the field of preparation of refractory materials, and discloses a preparation method of a wear-resistant and corrosion-resistant refractory material for a hazardous waste incinerator, which is characterized in that the refractory material comprises the following components in percentage by mass: (1) 75-82% of corundum (Al2O3) with the particle size of more than 0.074 mm and less than or equal to 3mm; (2) 7%-10% of chromium sesquioxide and Cr2O3 (the particle size is more than 0.074 mm and less than or equal to 2mm); (3) 2-5% of lanthanum oxide (La2O3) with the particle size of less than or equal to 0.074 mm; (4) 2-5% of silicon carbide (SiC) with the particle size of less than or equal to 0.074 mm; 5, 1-1.5% of an additive; and (6) 5%-10% of a binding agent. The wear-resistant material has the characteristics of good wear resistance, erosion resistance and the like, can be applied to seriously corroded and worn areas of parts such as a feed port and a drying section of the garbage incinerator, and has a wide market prospect.
本发明属于耐火材料制备领域，公开了一种危废垃圾焚烧炉用耐磨抗蚀耐火材料的制备方法，其特征在于，该耐火材料按质量百分比配比如下：①0.074mm＜粒径≤3mm(刚玉，Al2O3)75％～82％；②0.074mm＜粒径≤2mm(三氧化二铬，Cr2O3)7％～10％；③粒度≤0.074mm(氧化镧，La2O3)2～5％；④粒度≤0.074mm(碳化硅，SiC)2～5％；⑤外加剂1～1.5％；⑥结合剂5％～10％。本发明具有耐磨性好、抗侵蚀等特点，可应用于垃圾焚烧炉进料口、干燥段等部位腐蚀、磨损严重区域，具有广阔的市场前景。
