Sintered high-zirconium flat brick used for float glass kiln and preparation process of sintered high-zirconium flat brick
The invention discloses a sintered high-zirconium flat brick for a float glass kiln and a preparation process of the sintered high-zirconium flat brick, and relates to the technical field of glass kilns. The sintered high-zirconium flat brick comprises the following components in parts by weight: 50-95% of zirconium dioxide and hafnium dioxide, 4-45% of silicon dioxide, 0.5-3% of aluminum oxide, 0.1-2% of titanium dioxide and 0.1-1% of calcium oxide. The specific preparation process of the sintered high-zirconium flat brick comprises the following steps: (1) weighing raw materials; (2) mixingthe raw materials; (3) compression molding; (4) sintering; (5) grinding and polishing. The sintered high-zirconium flat brick provided by the invention has the advantages of high density, low porosity, high thermal shock resistance and corrosion resistance, and high zirconium dioxide content, effectively prolongs the service life of a glass kiln, reduces the replacement cost of key parts of the kiln and replaces the use cost of fused cast zirconia-corundum bricks; and the preparation process is simple, the preparation period is short, and the preparation method is suitable for wide popularization.
本发明公开了一种浮法玻璃窑炉使用的烧结高锆平板砖及其制备工艺，涉及玻璃窑炉技术领域，所述烧结高锆平板砖按重量份包括以下组分：二氧化锆+二氧化铪50％～95％、二氧化硅4％～45％、氧化铝0.5％～3％、二氧化钛0.1％～2％、氧化钙0.1％～1％；所述烧结高锆平板砖的具体制备工艺包括以下步骤：(1)原料称取；(2)原料混合；(3)压制成型；(4)烧结；(5)研磨抛光。本发明烧结高锆平板砖具有高密度、低气孔、高抗热抗震性及耐侵蚀性的优点，且二氧化锆含量较高，有效提高玻璃窑炉的使用寿命，降低更换窑炉关键部位并代替熔铸锆刚玉砖的使用成本；且本发明制备工艺简单，制备周期较短，适宜广泛推广。
