High-thermal-conductivity compact silica brick and preparation method thereof
The invention relates to a high-thermal-conductivity compact silica brick and a preparation method thereof. The silica brick can be selected from the following components in percentage by mass: 50%-60% of crystalline silicon sand, 5%-15% of cooked silica sand, 5%-15% of high-purity quartz glass, 15%-25% of crystalline silicon stone powder, 3%-6% of silica powder, 2%-5% of a silicon substrate, 0%-0.5% of an additive sintering promoter, 3.2%-4% of a mineralizer, 0.5%-1% of a binder and 1%-2% of a plasticizer. Through the mixing effect of the materials and the control of the sintering process, the silica brick product with low porosity, large volume density and high thermal conductivity is prepared, the service life of the silica brick is greatly prolonged, the working efficiency of a coke oven and a hot blast stove is improved, and energy conservation and environmental protection are facilitated.
本发明涉及一种高导热致密硅砖及其制备方法，所述硅砖可选自包括以质量分数计的如下组分：50％～60％的结晶硅砂、5％～15％的熟硅砂、5％～15％的高纯石英玻璃、15％～25％的结晶硅石粉、3％～6％的硅微粉、2％～5％的硅基质、外加0％～0.5％的促烧结剂、3.2％～4％的矿化剂、0.5％～1％的粘结剂、1％～2％的塑化剂。通过上述材料的混合作用及烧结过程的控制，制备出气孔率低、体密大、导热率高的硅砖制品，大大提高硅砖的使用寿命，且提高焦炉和热风炉的工作效率，并有助于节能环保。
