The invention relates to the technical field of refractory materials, and discloses a production method of a periclase brick for a regenerative chamber of a large float glass melting furnace, the periclase brick comprises the following raw materials by weight: 50 parts of fused magnesia, 50 parts of sintered high purity magnesia and a binder; and the weight part of the binding agent is 3-4% of the total weight of the fused magnesia and the sintered high-purity magnesia. According to the production method of the periclase brick for the regenerative chamber of the large float glass melting furnace, the periclase brick is used for replacing an electric smelting magnesite brick with the MgO content of 97.5% currently applied to the regenerative chamber of the glass melting furnace, the thermal shock stability is greatly improved, the creep rate is greatly reduced, the MgO content is improved, and the contents of SiO2 and Fe2O3 are reduced, so that the service life of the magnesia refractory material for the regenerative chamber of the glass melting furnace is greatly prolonged, an important step is made for prolonging the service life of the furnace, and the service life of the furnace is prolonged. According to the technical scheme, full-automatic hydraulic press forming and high-temperature tunnel kiln firing are adopted, and the advantages of being short in production period and high in efficiency are achieved.
本发明涉及耐火材料技术领域，且公开了一种大型浮法玻璃熔窑蓄热室用方镁石砖的生产方法，包括以下重量份数配比的原料：电熔镁砂50份、烧结高纯镁砂50份和结合剂；所述结合剂的重量份数为电熔镁砂和烧结高纯镁砂总重量的3％～4％。该大型浮法玻璃熔窑蓄热室用方镁石砖的生产方法，通过方镁石砖替代目前应用于玻璃熔窑蓄热室的MgO含量97.5％的电熔镁砖，因热震稳定性大幅度提高、蠕变率大幅度降低、MgO的含量提高、S iO2和Fe2O3的含量降低，很大程度上提高了玻璃熔窑蓄热室用镁质耐材的使用寿命，向窑炉长寿化迈出重要一步，本技术方案采用全自动液压机成型、高温隧道窑烧成，具有生产周期短、效率高的特点。
