Compared with other smelting method, vaccum induction smelting furnace is able to precisely control position 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 ponents of the design principles and calculation methods and design process and the necessary degree of intensity.
