Method for preparing magnesia carbon brick by recycling waste refractory material
The invention relates to the technical field of refractory materials, in particular to a method for preparing magnesia carbon bricks by recycling waste refractory materials. The technological process comprises the following steps: classifying and screening waste refractory materials, taking the total mass of reclaimed materials as a standard, proportioning according to a specified ratio, crushing, removing iron from chalcanthite, heating and drying, heating and mixing, firing and molding at high pressure, standing and cooling, and regenerating the magnesia carbon brick. According to the invention, the waste refractory material is utilized to generate the regenerated magnesia carbon brick, the process is simple, the waste of the waste refractory material can be reduced, and the recycling of the waste material and the improvement of the additional value are facilitated; the regenerated magnesia carbon brick produced by using the waste refractory material as the raw material has good thermal shock resistance and pressure resistance, and has considerable economic benefits.
本发明涉及耐火材料的技术领域，特别是一种废旧耐火材料回收制镁碳砖的方法。其工艺流程步骤为将废旧耐火材料分类、筛选、以再生料总质量为基准按照规定的配比进行配料、破碎、胆矾除铁，加热干燥，加热混炼后高压烧制成型，静置冷却后再生镁碳砖。本发明利用废旧耐火材料生成再生镁碳砖，工艺简单，可以减少对废旧耐火材料的浪费，有利于废料的再生利用和附加值的提高；以废旧耐火材料作为原料生产出的再生镁碳砖具有良好的耐热震性和耐压性能，具有可观的经济效益。
