Magnesium-calcium high-temperature spray coating
The invention provides a magnesium-calcium high-temperature spray coating. Raw materials of the magnesium-calcium high-temperature spray coating comprise magnesite clinker, metallurgical lime, metal silica powder and tricalcium phosphate as main raw materials, graphite or coke is also introduced, the granularity of the metallurgical lime is less than or equal to 0.1 mm, the granularity of the metal silica powder is less than or equal to 0.044 mm, the granularity of the tricalcium phosphate is less than or equal to 0.088 mm, the granularity of the graphite or coke is less than or equal to 0.1 mm, and the granularities of the magnesite clinker are respectively 0.5-0.088 mm and less than or equal to 0.088 mm. The magnesium-calcium high-temperature spray coating disclosed by the invention has the characteristics of low pollution, low risk, low cost, slag corrosion resistance, strong permeability resistance and the like, is convenient to take materials and convenient to construct, is suitable for parts such as a converter, a steel ladle, a tundish and the like in the steelmaking industry, and can obtain good economic and social benefits.
本发明提出一种镁钙质高温喷涂料，所述镁钙质高温喷涂料的原料，包括烧结镁砂、冶金石灰、金属硅粉、磷酸三钙为主要原料，同时引入石墨或焦炭，其中冶金石灰的粒度为≤0.1mm，金属硅粉粒度为≤0.044mm，磷酸三钙粒度为≤0.088mm，石墨或焦炭的粒度为≤0.1mm，烧结镁砂粒度分别为0.5‑0.088mm、≤0.088mm，本发明的镁钙质高温喷涂料具有低污染、低风险、低成本且抗渣侵蚀和抗渗透性强等特性，取材方便、便于施工，适用于炼钢工业转炉、钢包、中间包等部位，可获得良好经济和社会效益。
