Refractory castable for coal-fired boiler and preparation method thereof
The invention discloses a refractory castable for a coal-fired boiler and a preparation method of the refractory castable, and relates to the technical field of refractory materials. The refractory castable comprises the following components, by weight: 50 to 70 percent of refractory aggregate, 0 to 20 percent of lightweight aggregate, 5 to 10 percent of refractory powder, 0 to 8 percent of fly ash, 5 to 10 percent of andalusite powder, 0 to 8 percent of pore forming agent, 3 to 5 percent of silicon oxide micro powder, 5 to 10 percent of aluminum oxide micro powder, 3 to 5 percent of binding agent and 0.05 to 0.2 percent of water reducing agent. The material is good in heat preservation performance, capable of reducing heat dissipation loss and coal consumption, resistant to high temperature, high in strength and good in abrasion resistance, the coal-fired boiler can be protected, and the service life of the coal-fired boiler can be effectively prolonged.
本发明公开了一种用于燃煤锅炉的耐火浇注料及制备方法，涉及耐火材料技术领域，该用于燃煤锅炉的耐火浇注料以质量分数计，包括如下组分：耐火骨料：50～70％、轻质骨料：0～20％、耐火粉料：5～10％、粉煤灰：0～8％、红柱石粉：5～10％、造孔剂：0～8％、氧化硅微粉：3～5％、氧化铝微粉：5～10％、结合剂：3～5％、减水剂：0.05～0.2％。该材料保温性能好，能够减少散热损失，降低煤耗，同时该材料耐高温、强度高、耐磨性好，对燃煤锅炉能够起到保护作用，有效提高其使用寿命。
