Composite castable for organic solid waste pyrolysis carbonization furnace and preparation method of composite castable
The invention relates to a composite castable for an organic solid waste pyrolysis carbonization furnace and a preparation method of the composite castable. The castable comprises the following raw materials in percentage by mass: 30-45% of corundum particles, 20-40% of silicon carbide micro powder, 10-15% of calcined alumina micro powder, 6-9% of magnesium aluminate spinel fine powder, 3-5% of micro silicon powder, 2-5% of pure calcium aluminate cement, 1-2% of sodium tripolyphosphate, 0.5-1% of a special additive and 4-10% of water, totaling 100%, wherein the special additive is a pore forming agent and a water reducing agent. According to the optimized gradation design theory, the components of the matrix alloy are self-designed, a proper amount of elements are selected, the matrix alloy has a high-temperature-resistant hard phase after heat treatment, the matrix hardness of the matrix alloy at high temperature is guaranteed, meanwhile, a silicon carbide reinforced phase is added, the high-temperature-resistant performance of the composite material is further improved, and the composite material is easy to apply and popularize.
本发明涉及一种有机固废热解炭化炉用复合浇注料及其制备方法。该浇注料包括按照质量百分数计的如下原料：刚玉颗粒30~45%、碳化硅微粉20~40%、煅烧氧化铝微粉10~15%、镁铝尖晶石细粉6~9%、微硅粉3~5%、纯铝酸钙水泥2~5%、三聚磷酸钠1~2%、专用添加剂0.5~1%、水4~10%，总计100%；所述的专用添加剂为造孔剂和减水剂。本发明根据优化级配设计理论，自行设计基体合金成分，选用适量的元素含量，使基体合金热处理后出现耐高温硬质相，保证其在高温下的基体硬度，同时添加了碳化硅增强相，进一步提升复合材料的耐高温性能，易于推广应用。
