10kg真空中频感应炉装置设计 摘 要 目前，随着航天、航空、军工、核电、能源、化工等领域的不断向前发展，不仅特殊钢、精密合金、电热合金、高温合金及耐蚀合金等特殊合金的的需求量越来越大，而且对其质量要求更加苛刻，这就促进了真空感应炉的发展与研究。与其他冶炼方法相比，真空感应炉熔炼能够精确控制所炼钢种或合金的成分；钢或合金中气体和非金属夹杂物的含量水平远远低于其他熔炼方法；真空感应炉的温度相对来说比较容易控制，而控制压力水平就是真空感应炉最显著的特点。 本课题研究的对象是10kg真空中频感应炉装置的设计，包括工艺参数的选择，坩埚材料的选择以及尺寸的设计，感应器材料的选择与结构的设计，倾炉机构的选择，冷却系统的设计等，本课题的设计论述出了各部分的设计方法与原则以及计算设计过程和必要的强度校核。 关键词 真空感应炉设计  ABSTRACT At present,with the continuous development of some areas,such as aerospace,aviation,military industry, nuclear power,energy and chemical area, not only the demand of special alloy—heat-resisting alloy, high temperature alloy, corrosion resistant alloy—are increasing, but the quality requirements of this special alloy are becoming more stringent.All of this promoted the development and research of vaccum induction furnace. Compared with other smelting method, vaccum induction smelting furnace is able to precisely control composition of steel or alloy, and gas and nonmetallic inclusions in steel or alloy are far below other smelting method.The temperature of the vacuum induction furnace is relatively easy to control, and control the pressure level is the most distinguishing feature of vacuum induction furnace. This research sets the target of 10 kg vacuum intermediate frequency induction furnace equipment design, including the selection of process parameters, the selection of crucible materia and size design, material selection and structure design of sensors, furnace tilting mechanism and cooling system selection. the topics addressed in the design of the various components of the design principles and calculation methods and design process and the necessary degree of intensity.
