Carbon-free magnesium composite sealing brick for VOD steel ladle and preparation method thereof
The invention relates to the technical field of metallurgy, in particular to a carbon-free magnesium composite sealing brick for a VOD steel ladle and a preparation method of the carbon-free magnesiumcomposite sealing brick. The carbon-free magnesium composite sealing brick is prepared from 70-90 parts of fused magnesite, 1-5 parts of zircon sand, 1-10 parts of fused magnesia-alumina spinel, 1-5parts of Mg-alpha/beta-SiAlON multiphase material, 1-5 parts of alpha-alumina micro powder and 2.5-4 parts of magnesia-alumina gel powder. By obtaining the carbon-free magnesium composite sealing brick for the VOD steel ladle, the problems that in the prior art, when liquid resin is used as a binding agent for preparing the steel ladle brick, the environment is influenced to a certain extent, andwhen the resin is completely carbonized, a large amount of smoke is exhausted, so that the porosity of the steel ladle brick is increased, the structure is loose, and oxidizing atmosphere erosion is aggravatedespecially under the condition of VOD steel ladle smelting oxygen blowing are solved..
本发明涉及冶金技术领域，尤其是涉及一种VOD钢包用无碳镁质复合封口砖及其制备方法；包括电熔镁砂70‑90份、锆英砂1‑5份、电熔镁铝尖晶石1‑10份、Mg‑α/β‑SiAlON复相材料1‑5份、α氧化铝微粉1‑5份和镁铝凝胶粉2.5‑4份；通过VOD钢包用无碳镁质复合封口砖的获得以解决现有技术中存在的使用液体树脂作为结合剂制备钢包砖时，对环境有一定的影响，树脂完全碳化时，大量烟气的排出导致钢包砖气孔率增大，结构疏松，氧化气氛侵蚀加剧，尤其是VOD钢包冶炼吹氧的条件下。
