Zirconium refractory material prepared by fusion casting method and preparation method thereof
The invention provides a zirconium refractory material manufactured by a fusion casting method and a preparation method thereof, and belongs to the technical field of fusion casting refractory materials. The refractory material provided by the invention is a water gap and a sliding plate, and contains ZrO2, HfO2, CaO, MgO, Y2O3, Fe2O3, TiO2, Al2O3 and SiO2. According to the invention, the high-temperature fused zirconia melt is directly cast into the high-temperature-resistant mold, and the zirconium water gap and the sliding plate are produced through fusion casting, so that the process for producing the zirconium water gap and the sliding plate is simplified, and the high-temperature sintering energy consumption of the zirconium water gap and the sliding plate produced through compression molding and sintering procedures is saved; the prepared zirconium nozzle and sliding plate are high in volume density, crystal phase components in the manufactured product are uniformly distributed, and micropores in the product are also uniformly distributed, so that the thermal compressive strength, thermal shock resistance and scouring resistance are multiplied.
本发明提供了一种熔铸法制造锆质耐火材料及其制备方法，属于熔铸耐火材料技术领域。本发明的耐火材料为水口和滑板，含有ZrO2、HfO2、CaO、MgO、Y2O3、Fe2O3、TiO2、Al2O3和SiO2。本发明将电熔的氧化锆高温熔液直接浇铸到耐高温模具中，熔铸生产出锆质水口和滑板，既简化了生产锆质水口和滑板的工艺，又省掉压制成型和烧结工序生产出来的锆质水口和滑板的高温烧结能耗，制备的锆质水口和滑板的体积密度高，且制造的制品中晶相组成分布均匀，内部的微气孔也分布均匀，导致热态抗压强度、抗热震性和耐冲刷性能成倍提升。
