Method for manufacturing erosion-resistant magnesium crucible by adopting cold isostatic pressing technology
The invention discloses a method for manufacturing an erosion-resistant magnesium molded crucible by adopting a cold isostatic pressing technology, and belongs to the technical field of refractory materials. The raw material used in the invention is fused magnesia sand, the content of magnesium oxide is greater than or equal to 95.5 wt.%, the content of CaO is 1-2 wt.%, and the content of SiO2 is 0.5-1 wt.%. The preparation method comprises the following steps: preparing magnesite according to a certain particle size composition requirement, adding a certain amount of binder and sintering agent, and uniformly mixing; the binder is deionized water, and the sintering agent is high-purity ZrO2 powder. And carrying out cold isostatic pressing molding, maintaining the pressure for 3-5 minutes, taking out, and sintering in a high-temperature kiln at 1660 +/-20 DEG C. The invention discloses a method for preparing a magnesium crucible integrally formed outside a furnace. The magnesium crucible formed by the method has good melt erosion resistance, and can meet the induction melting production requirements of iron-based and nickel-based high-temperature alloy or stainless steel alloy materials.
本发明公开了一种采用冷等静压技术制造耐侵蚀镁质成型坩埚的方法,属于耐火材料技术领域。本发明所用原材料为电熔氧化镁砂,氧化镁含量≥95.5wt.%,CaO含量1‑2wt.%,SiO2含量0.5‑1wt.%。将镁砂按照一定的粒度组成要求配好后,加入一定量的粘结剂和烧结剂并混合均匀;所用的粘结剂为去离子水,烧结剂为高纯ZrO2粉。采用冷等静压成型,保压3~5min后取出,再在高温窑内1660℃±20℃烧结。本发明公开了一种制备炉外一体成型镁质坩埚的方法。该方法成型的镁质坩埚具有良好的抗熔体侵蚀性能,可满足铁基、镍基高温合金或不锈钢合金材料的感应熔炼生产要求。
