Preparation method of anti-sticking kiln lining for dead-burned magnesia shaft kiln
The invention relates to a preparation method of an anti-sticking kiln lining for a dead-burned magnesia shaft kiln, wherein the preparation method comprises the steps: by using fused magnesia fine powder, fused magnesite-chrome sand fine powder, chrome green micro powder and fused magnesite-chrome sand materials with different granularities as refractory raw materials and paper pulp waste liquidas a binding agent, mixing, forming, drying and firing to prepare a once-fired kiln lining; and taking the magnesium-chromium sol as a reinforcing agent, and preparing the anti-sticking kiln lining for the dead-burnt magnesium oxide shaft kiln by adopting a vacuum infiltration process and a drying and secondary sintering process. The anti-sticking kiln lining used for the dead-burned magnesia shaft kiln and prepared by the method has the advantages that the production cost is low, the anti-sticking performance of the kiln lining is greatly improved, the operation and the implementation are easy, and the like.
本发明专利涉及一种重烧氧化镁竖窑用防粘窑炉衬制备方法，电熔镁砂细粉、电熔镁铬砂细粉、铬绿微粉料和不同粒度的电熔镁铬砂料作为耐火原料，纸浆废液做为结合剂，经过混合、成型、干燥和烧成制备一次烧成炉衬。再以镁铬溶胶为增强剂，采用真空浸渗工艺，经干燥和二次烧成工艺，制备出重烧氧化镁竖窑用防粘窑炉衬。使用本发明方法制备的一种重烧氧化镁竖窑用防粘窑炉衬具有生产成本低廉，大幅提升炉衬的防粘性能，易于操作实施等优点。
