Novel large bottom brick special for float glass kiln molten tin bath high-temperature section and preparation method thereof
The invention belongs to the technical field of refractory materials, and particularly relates to a novel large bottom brick special for a float glass kiln molten tin bath high-temperature section anda preparation method thereof. The large bottom brick is prepared from the following raw materials in percentage by mass: 60-70% of synthetic material; 1-5% of refractory cement; 5-15% of sintered corundum; 5 -15% of mullite fine powder; 2-5% of silica fume; the synthetic material is prepared from the following raw materials in percentage by mass: 30-40% of Suzhou soil; 30-40% of bauxite; 20-25% of mullite; and 2-8% of a binding agent. After sintering the synthetic material, the materials are mixed, high-frequency pouring molding is performed and sintered in a kiln to obtain the finished product. The large bottom brick prepared by the method is high in strength, high in density and low in porosity, the air tightness of the whole tin bath can be improved, the oxygen pollution is reduced andthe cyanea phenomenon is avoided, free substances in tin liquor and drippings at the top of the tin bath are reduced, the yield of glass is increased by 5% or above and the profits of glass enterprises can be effectively increased.
本发明属于耐火材料技术领域，具体涉及一种新型浮法玻璃窑锡槽高温段专用的底部大砖及其制备方法。所述的底部大砖，原料的质量百分比组成如下：合成料60‑70％；耐火水泥1‑5％；烧结刚玉5‑15％；莫来石细粉5‑15％；微硅粉2‑5％；合成料由以下质量百分比的原料制成：苏州土30‑40％；铝矾土30‑40％；莫来石20‑25％；结合剂2‑8％。先烧成合成料后，再经混料、高频浇筑成型后入窑烧成成品。本发明制备的底部大砖，强度大，密度高、气孔率低，能够使得整体锡槽气密性提升，氧污染降低，同时不产生霞石化现象，减少锡液中游离物和锡槽顶部滴落物，使玻璃的成品率增加5％以上，可有效提高玻璃企业的利润。
