、 電極鑄造和水平連鑄的組合。多功能真空感應(yīng)爐,有利于提高鑄造用鋼的質(zhì)量,增加鑄造鋼和合金的品種,最終目的是為了提高現(xiàn)有冶金裝備與技術(shù)水平以及材料質(zhì)量,得到高水平的優(yōu)質(zhì)產(chǎn)品。 國內(nèi)外真空感應(yīng)爐使用狀況及發(fā)展趨勢 真空感應(yīng)爐是特殊鋼、精密合金、電熱合金、高溫合金及耐蝕合金等特殊合金生產(chǎn)的重要工序之一,在航天、航空、軍工、核電等領(lǐng) 域的材料生產(chǎn)中起著重要的作用。 為了適應(yīng)尖端技術(shù)對高性能及新型金屬材料的需求,真空冶金已成為現(xiàn)代冶金的一個重要領(lǐng)域。 關(guān)鍵詞 真空 , 感應(yīng)爐 , 設(shè)計 XXXXXXXXXXXXXX 論文) ABSTRACT Ⅱ II 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—heatresisting alloy, high temperature alloy, corrosion resistant alloy—are increasing, but the quality requirements of this special alloy are being more 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 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. Key words vacuum, induction furnace, design XXXXXXXXXXXXX(論文) 目 錄 I 目 錄 摘 要 ..............................................................
