Induction melting system including gas exhaust |
摘要 |
An annular exhaust gas passage 2 and an airtight retention member 3 for keeping the inside of a crucible induction furnace 1 airtight are installed on the top of the furnace 1, and an exhaust system under atmospheric pressure is connected to a valve 4 via an air duct that penetrates the airtight retention member 3. In addition, a sealing cover 7 that has a valve 8, which can be opened and closed, is used to keep the inside of the furnace airtight, while a system under reduced pressure is connected to the valve 8. These two systems constitute the entire exhaust system./!
