Heat-insulating refractory material for air supply device of iron-making blast furnace
The invention belongs to the field of refractory materials, and particularly relates to a heat-insulating refractory material for an air supply device of an iron-making blast furnace, which comprises the following components in percentage by weight: 10-15% of flint clay aggregate with the particle size of 3-5mm, 5-10% of flint clay aggregate with the particle size of 1-3mm, 20-25% of flint clay aggregate with the particle size of 0-1mm, 5-10% of flint The anti-explosion coating is prepared from the following components in percentage by weight: 5 to 10 percent of silica powder, 6 to 12 percent of kyanite, 5 to 8 percent of alpha-aluminum oxide, 7 to 12 percent of high bauxite powder, 8 to 15 percent of cement, 3 to 8 percent of chromium oxide green, 0.5 to 1 percent of melamine, 0.5 to 1 percent of hexacyanamide, 2 to 5 percent of floating beads and 1 to 3 percent of anti-explosion fiber. And 7-12% of water is added. The obtained refractory material is high in refractoriness, breaking strength and compression strength, small in linear change rate, small in density, small in heat conductivity coefficient, resistant to high temperature, scouring and oxidation, long in service life, stable in performance and good in heat insulation effect, and it is guaranteed that an iron-making blast furnace air supply device is safely used.
本发明属于耐火材料领域，具体涉及一种炼铁高炉送风装置用隔热耐火材料，所述隔热耐火材料组分及其重量百分比为：焦宝石骨料：3‑5mm：10‑15％、1‑3mm：5‑10％、0‑1mm：20‑25％；硅微粉5‑10％，蓝晶石6‑12％，α‑氧化铝5‑8％，高铝矾土粉7‑12％，水泥8‑15％，氧化铬绿3‑8％，三聚氰胺0.5‑1％，六偏氰胺0.5‑1％，漂珠2‑5％，防爆纤维1‑3％；外加水7‑12％。本发明所得耐火材料耐火度高，抗折强度和耐压强度高，线性变化率小，密度小，导热系数小，耐高温、耐冲刷、抗氧化、寿命长、性能稳定、隔热保温效果好，保证炼铁高炉送风装置安全使用。
