Nitride composite refractory material for titanium alloy smelting and preparation method thereof
The invention belongs to the technical field of titanium alloy smelting, and discloses a nitride composite refractory material for titanium alloy smelting and a preparation method thereof. The nitride composite refractory material for titanium alloy smelting is prepared from the following components in percentage by mass: 10-40% of boron nitride powder, 60-90% of aluminum nitride powder and the balance of additives, the addition amount of the additive is 3-6% of the total mass of the boron nitride and the aluminum nitride; the additive is yttrium oxide. The invention also discloses a preparation method of the nitride composite refractory material. The composite refractory material is prepared by adopting a powder metallurgy technology. The refractory material disclosed by the invention has high density, high corrosion resistance, thermal shock resistance and excellent high-temperature chemical inertness, hardly reacts with a titanium alloy melt, is simple in preparation process and low in cost, and can be used for smelting low-energy-consumption and high-quality titanium alloy.
本发明属于钛合金熔炼的技术领域，公开了一种钛合金熔炼用氮化物复合耐火材料及其制备方法。所述钛合金熔炼用氮化物复合耐火材料，由氮化硼、氮化铝以及添加剂制备而成：按质量百分比计，氮化硼粉末10％～40％，氮化铝粉末60％～90％；添加剂的加入量为氮化硼和氮化铝总质量的3％～6％；所述添加剂为氧化钇。本发明还公开了氮化物复合耐火材料的制备方法。本发明采用粉末冶金技术制备复合耐火材料。本发明的耐火材料具有高致密度、高耐腐蚀性、抗热冲击性以及优异的高温化学惰性，几乎不与钛合金熔体发生反应，且制备工艺简单，成本低廉，可用于低能耗、高品质钛合金的熔炼。
