Components of high-erosion-resistance zirconia corundum brick, melting process, and melting device
The invention discloses components of a high-erosion-resistance zirconia corundum brick, a melting process and a melting device. The high-erosion-resistance zirconia corundum brick comprises the following components in percentage by mass: 63-68% of zirconium dioxide, 3-10% of silicon dioxide, 20-32% of aluminum oxide, 0.3-1% of sodium oxide and 0.5-1% of diboron trioxide. The melting process comprises the following procedures: retaining 1/3 to 2/3 of fused materials in a furnace body; mixing and smashing materials in all the components of the zirconia corundum brick into particles with particle sizes in a range of 2-3 mm; and then, introducing the particles into the upper end of the highest liquid level of the furnace body. The melting device comprises a smashing box and a three-phase electric arc furnace, wherein a feeding port is formed in the upper end of the smashing box, and a stirring cavity is formed in the inner upper end of the smashing box. According to the components of the high-erosion-resistance zirconia corundum brick, the melting process and the melting device, the high-erosion-resistance zirconia corundum brick is allowed to have the characteristics of compact internal structure, high compressive strength, high molten glass erosion resistance and low glass phase exudation amount, the service life of a glass kiln is prolonged, glass defects are reduced, and glass quality is improved.
本发明公开了一种高抗侵蚀锆刚玉砖的组分及熔化工艺及装置，按其组分质量百分比为：二氧化锆63％～68％、二氧化硅3％～10％、三氧化二铝20％～32％、氧化钠0.3％～1％、三氧化二硼0.5％～1％，其熔化工序：炉体中保留1/3‑2/3的熔融物料，将锆刚玉砖的各组分中物质混合搅碎至粒径2～3mm颗粒，然后通入至炉体最高液位的上端，其熔化装置：包括粉碎箱和三相电弧炉，粉碎箱的上端设置有进料口，粉碎箱的内部上端设置有搅拌腔，本高抗侵蚀锆刚玉砖的组分及熔化工艺及装置使其具有内部结构致密，抗压强度大，抗玻璃液侵蚀性强，玻璃相渗出量低的特点，并帮助延长玻璃窑炉寿命，减少玻璃缺陷，改善玻璃质量。
