Magnesium aluminate spinel crucible for high-temperature alloy and preparation method thereof
The invention relates to the technical field of refractory materials. The magnesium aluminate spinel crucible for the high-temperature alloy comprises the following raw materials: magnesium aluminatespinel, SiC, graphite, an antioxidant and a binding agent, the magnesium aluminate spinel comprises magnesium aluminate spinel particles and magnesium aluminate spinel powder, and the SiC comprises SiC particles and SiC powder; the method comprises the following steps: putting the raw materials into a stirrer according to a weight ratio, and stirring to obtain pug; putting the stirred pug into a sealed container for ageing; putting the aged pug into a rubber mold, putting the rubber mold into an isostatic pressing machine, and carrying out pressure molding to obtain a semi-finished product; putting the formed semi-finished product into a drying kiln to be dried; and putting the dried semi-finished product into a firing kiln, and firing to obtain the finished crucible. The crucible disclosed by the invention has high thermal shock resistance and high erosion resistance, and the service life of the crucible at the use temperature of not higher than 1300 DEG C can reach 100 heat times orabove.
本发明涉及耐火材料技术领域，具体涉及一种高温合金用镁铝尖晶石坩埚及其制备方法，坩埚原料包括镁铝尖晶石、SiC、石墨、抗氧化剂和结合剂，其中镁铝尖晶石包括镁铝尖晶石颗粒和镁铝尖晶石粉末，SiC包括SiC颗粒和SiC粉末；方法包括：将各原料按重量比例投入搅拌机中，搅拌得到泥料；将搅拌好的泥料装入密封容器中困料；将困好的泥料装入橡胶模具中，并将橡胶模具放入等静压压机中，经压力成型，得到半成品；将成型后的半成品放入烘干窑中烘干；将烘干后的半成品装入烧成窑，烧成制得成品坩埚。本发明坩埚具备高抗热震和高耐侵蚀性能，在不高于1300℃的使用温度下使用寿命可达到100炉次以上。
