Composite corundum wear-resistant plastic refractory used for CFB target region and preparation method of composite corundum wear-resistant plastic refractory
The invention relates to the technical field of refractory materials, in particular to a composite corundum wear-resistant plastic refractory for a CFB target region and a preparation method, and the plastic refractory comprises the following components in parts by weight: 30-40 parts of boron nitride composite corundum particles, 10-30 parts of bauxite particles, 10-20 parts of mullite powder, 15-30 parts of silicon carbide powder, 4-8 parts of calcium aluminate cement, 10-15 parts of a binding agent and 2-5 parts of an additive. The plastic refractory is excellent in fire resistance, the boron nitride composite corundum particles are used as aggregate, and the boron nitride composite corundum particles have good high-temperature lubricating performance and thermal shock resistance, so that the plastic refractory can still have good wear resistance in a high-temperature environment, erosive wear of a target area of a CFB boiler is reduced, and the service life of the CFB boiler is prolonged. And the service life of the CFB boiler is prolonged.
本发明涉及耐火材料技术领域，具体涉及一种用于CFB靶区的复合刚玉耐磨可塑料及制备方法，可塑料按重量份数计包括以下成分：氮化硼复合刚玉颗粒30～40份、铝矾土颗粒10～30份、莫来石粉10～20份、碳化硅粉15～30份、铝酸钙水泥4～8份、结合剂10～15份、添加剂2～5份。本发明的可塑料耐火性能优异，并使用了氮化硼复合刚玉颗粒作为骨料，氮化硼复合刚玉颗粒具备良好的高温润滑性能与抗热震性能，使可塑料在高温环境下依然能够具备较好的耐磨性能，减少了CFB锅炉靶区的冲刷磨损，提高了CFB锅炉的使用寿命。
