Baking-free magnesia-alumina spinel brick for RH dip pipe and preparation method of baking-free magnesia-alumina spinel brick
The invention relates to an unfired magnesia-alumina spinel brick for an RH dip pipe and a preparation method of the unfired magnesia-alumina spinel brick; high-volume-density high-purity sintered magnesia, fused magnesia and high-volume-density high-purity sintered magnesia-alumina spinel are used as main raw materials, a composite additive is added, and the unfired magnesia-alumina spinel brickis prepared by mixing, grinding, compacting and baking, and has the advantages of high thermal shock stability and long service life. The unfired magnesia-alumina spinel brick has the characteristicsof simple process, low production cost and high product cost performance, can replace magnesite-chrome bricks to produce the RH dip pipe, and accelerates the chromate-free pace of the RH dip pipe.
本发明涉及一种RH浸渍管用免烧镁铝尖晶石砖及其制备方法，采用高体密高纯烧结镁砂、电熔镁砂和高体密高纯烧结镁铝尖晶石为主要原料，通过添加复合添加剂经混碾压坯烘烤制得免烧镁铝尖晶石砖，具有热震稳定性高、寿命长，生产成本低廉、产品性价比高的特点，可代替镁铬砖生产RH浸渍管，加速RH浸渍管无铬化的步伐。
