Micropore-containing refractory material lining plate for coke tank bottom gate and preparation method of micropore-containing refractory material lining plate
The invention relates to a refractory material lining plate containing micropores for a coke tank bottom gate. The refractory material lining plate comprises the following raw materials in percentage by weight: 40-50% of sintered mullite with the particle size of 5-1mm; 5-10% of andalusite, sillimanite or kyanite with a particle size of less than 0.1 mm; 2-5% of hollow glass beads with a particle size of 0.1-1 mm; 30-45% of fused mullite powder with the particle size of less than 0.088 mm; 0.5 to 3 percent of ball clay; 3-10% of silicon carbide with a particle size of 1-0.1 mm; 0.5-3% of ferrosilicon alloy powder with the particle size smaller than 0.088 mm; 0.05 to 0.5 percent of a potassium silicate solution; and 0.5-5% of a sodium alginate aqueous solution. The preparation method comprises the following steps: mixing solid raw materials; adding a potassium silicate solution and sodium alginate water, and uniformly stirring; pressing into a green body and naturally drying; performing baking; and firing at high temperature. The lining plate is good in rapid cooling and rapid heating resistance and not prone to cracking, the service life of the lining plate is prolonged to 6 months or above, and the temperature of the outer surface of the bottom of the bottom gate is greatly reduced.
一种含微孔的焦罐底闸门用耐火材料衬板，其原料组成及wt%为：粒度在5～1mm烧结莫来石：40～50%；粒度小于0.1mm的红柱石或硅线石或蓝晶石：5～10%；粒度在0.1～1mm的空心玻璃微珠：2～5%；粒度小于0.088mm的电熔莫来石粉：30～45%；球粘土：0.5～3%；粒度在1～0.1mm的碳化硅：3～10%；粒度小于0.088mm的硅铁合金粉：0.5～3%；硅酸钾溶液0.05～0.5%；海藻酸钠水溶液：0.5～5%。制备方法：将固体原料混合；加入硅酸钾溶液及海藻酸钠水并搅拌均匀；压制成生坯并自然干燥；烘烤；高温烧制。本发明不仅耐受急冷急热性能好，不易开裂，且衬板使用周期延长到6个月以上，底闸门底部外表温度得以大幅降低。
