Castable for high-temperature garbage incinerator and preparation method of castable
The invention specifically relates to castable for a high-temperature garbage incinerator and a preparation method of the castable. According to the technical scheme, 75wt%-95wt% of silicon carbide, 1wt%-8wt% of expanded graphite, 0.5wt%-4wt% of monatomic silicon powder, 0.5wt%-6wt% of silica powder and 2wt%-8wt% of iron nitrate nonahydrate are taken as raw materials; according to the percentage of the raw materials, iron nitrate nonahydrate is dissolved in silica sol accounting for 5wt%-15wt% of the raw materials, and a mixed solution is obtained; a water reducer accounting for 0.1wt%-0.3wt% of the raw materials is mixed with raw materials except iron nitrate nonahydrate and uniformly stirred, and a premix is obtained; the mixed solution and the premix are mixed and uniformly stirred, and the castable for the high-temperature garbage incinerator is prepared. The prepared castable for the high-temperature garbage incinerator has the characteristics of excellent high-temperature mechanical property, high thermal conductivity, high oxidation resistance, good thermal shock stability, long service life, energy conservation and environmental protection.
