Preparation method of magnesium oxide-zirconium oxide complex-phase porous high-thermal-shock-resistance refractory block
The invention discloses a preparation method of a magnesium oxide-zirconium oxide complex-phase porous high-thermal-shock-resistance refractory block. According to the invention, fused magnesite powder or sintered magnesite powder is used as a raw material, dextrin, methylene cellulose or resin is used as a binding agent, and a slurry required by 3D printing is prepared. The magnesium oxide-zirconium oxide complex-phase porous high-thermal-shock refractory block can be obtained through 3D printing forming, drying, primary sintering, zirconium oxide sol dipping secondary drying and secondary sintering. The matrix of the magnesium oxide-zirconium oxide complex-phase porous high-thermal-shock refractory block prepared by the method is molded by adopting a 3D printing technology, so that the size and distribution of pores can be designed. And a zirconia sol infiltration matrix sintering process is adopted, so that the sintering of the refractory block is promoted, and the strength of the block is improved. Through reasonable compounding of magnesium oxide and zirconium oxide refractory compositions, the refractory performance and the use performance are greatly improved.
本发明以电熔镁砂粉或烧结镁砂粉为原料，以糊精、亚甲基纤维素或树脂为结合剂，制备3D打印所需浆料。经3D打印成型、干燥、一次烧成、浸氧化锆溶胶二次干燥、二次烧成，便可得到氧化镁‑氧化锆复相多孔高热震耐火块体。本方法制备的氧化镁‑氧化锆复相多孔高热震耐火块体的基体由于采用3D打印技术成型，可设计气孔大小和分布。采用氧化锆溶胶浸渗基体烧成工艺，促进了耐火块体的烧结，使块体的强度得到提高。通过氧化镁‑氧化锆耐火组成合理复配，大大地提高了耐火性能和使用性能。
