摘　　要：研究了真空感应熔炼气雾(VIGA)技术中使用高温陶瓷材料对GH4169雾化结果的影响。利用电子秤、氧氮分析仪和X射线分析雾化后不同氮化硼高温陶瓷材料用量对包铁质量、金属粉末的氧氮、高密夹杂的影响。结果表明:在浇口杯处涂抹氮化硼高温陶瓷材料可以有效地缩短清理包铁时长。随着氮化硼高温陶瓷材料用量的增加,包铁质量明显减少,采用VIGA设备生产的GH4169金属粉末氧氮值及非金属夹杂物均合格。另外,在大坩埚内部涂抹不同量的高温陶瓷材料也对金属粉末没有任何影响。本研究对了解在VIGA设备中通过使用氮化硼高温陶瓷材料来提高浇口杯寿命和减少包铁质量,具有指导意义和参考价值。s:This paper investigates the effect of using high-temperature ceramic materials in vacuum induction melting aerosol(VIGA)technology on the atomization results of GH4169.Electronic scales,oxygen and nitrogen analyzers and X-rays were used to analyze the effects of different boron nitride high temperature ceramic material dosages on the weight of clad iron,oxygen and nitrogen of metal powder,and high density inclusions after atomization.The results show that applying boron nitride high temperature ceramic material at the sprue cup can effectively shorten the cleaning time of clad iron.With the increase of the dosage of boron nitride high temperature ceramic material,the weight of clad iron is obviously reduced,and the oxygen and nitrogen value of metal powder and non-metallic inclusions of GH4169 produced by VIGA equipment are qualified.On the other hand,applying different amounts of high temperature ceramic materials inside the large crucible also did not have any effect on the metal powder.This paper has guiding significance and reference value for understanding the use of boron nitride high temperature ceramic material in VIGA equipment to improve the life of sprue cup and reduce the weight of clad iron.
