Anti-skinning zirconite-based alkali-resistant brick for cement kiln and preparation method of anti-skinning zirconite-based alkali-resistant brick
The invention provides an anti-skinning zirconite-based alkali-resistant brick for a cement kiln and a preparation method of the anti-skinning zirconite-based alkali-resistant brick. The alkali-resistant brick is prepared from the following raw materials in parts by mass: 65-80 parts of a single crystal phase mullite homogenized material, 5-10 parts of zirconium kyanite powder, 5-15 parts of zirconite powder, 1-3 parts of silica fume powder, 1-3 parts of metal silicon powder, 5-8 parts of white mud and 3-4 parts of a dextrin solution. The anti-skinning zirconite-based alkali-resistant brick for the cement kiln provided by the invention has more excellent low porosity, high strength, high refractoriness under load, excellent alkali corrosion resistance and anti-skinning performance, can replace a silicon carbide product in the market to be applied to an easy-skinning preheater system of the cement kiln, overcomes the problem of hydration oxidation of a silicon carbide brick, and greatly reduces the thermal conductivity and the volume density of the material.
本发明提供一种水泥窑用抗结皮锆英石基耐碱砖及其制备方法，该耐碱砖由包括以下质量份的原料制备而成：单晶相莫来石均质料65～80份，锆蓝晶石粉5～10份，锆英石粉5～15份，硅灰粉1～3份，金属硅粉1～3份，白泥5～8份，糊精溶液3～4份。本发明提供的水泥窑用抗结皮锆英石基耐碱砖具有更加优异的低气孔，高强度，高荷重软化温度、优良抗碱侵蚀性能和抗结皮性能，能够代替市场的碳化硅质产品应用水泥窑易结皮的预热器系统，并克服碳化硅砖水化氧化问题，大幅降低材料的导热率和体积密度。
