Refractory material and preparation method and application thereof
The invention belongs to the technical field of refractory material preparation, and particularly relates to a refractory material and a preparation method and application thereof. The refractory material comprises dicalcium fused magnesite, an antioxidant, a sintering agent, graphite and phenolic resin, the mass fraction of magnesium oxide in the dicalcium fused magnesite is not less than 98%, and the magnesium oxide with the magnesium oxide content not less than 98% and the antioxidant are compounded for use, so that the refractory material has good high temperature resistance, mechanical strength and oxidation resistance, and the service life of the refractory material is prolonged. When the refractory material is used for the AOD converter, the furnace life can be prolonged to 150 furnaces, and the refractory material cost of stainless steel production is reduced.
本发明属于耐火材料制备技术领域，具体涉及一种耐火材料及其制备方法和应用。该耐火材料包括二钙电熔镁砂、抗氧化剂、烧结剂、石墨和酚醛树脂，其中，所述二钙电熔镁砂中氧化镁的质量分数不小于98%，通过氧化镁含量不小于98%的镁砂和抗氧化剂复配使用，可以使耐火材料具有较好的耐高温性、机械强度和抗氧化性能，当该耐火材料用于AOD转炉时，可以使炉龄提升至150炉，提高了AOD转炉的使用寿命，降低不锈钢生产的耐材成本。
