Vacuum smelting device for intermediate frequency furnace

Abstract

The invention discloses a vacuum smelting device for an intermediate frequency furnace. The vacuum smelting device comprises a furnace body; a bearing plate is fixedly installed on the outer side wallof the furnace body; an assembling plate is fixedly installed at the upper end of the bearing plate through a supporting column; a flow dividing assembly communicates with a filtering assembly through a first air pipe; one end of a corrugated pipe penetrates through a cover in a sealing mode and communicates with the furnace body; a first vacuum pump and a second vacuum pump are fixedly installedon the bearing plate; the power of the first vacuum pump is smaller than that of the second vacuum pump; a third air pipe communicates with the second vacuum pump; and a display screen of the flow dividing assembly can display the vacuum degree in the flow dividing assembly. Vacuum pumping operation of different gears is achieved, the purposes of high air pumping efficiency and low energy consumption are achieved, the structure is simple, use is convenient, the service life of a vacuum gauge is greatly prolonged, a filtering plate is detachably installed on a second box body, the filtering effect is achieved, and dismounting and cleaning are convenient.

Description

technical field [0001] The invention relates to the technical field of intermediate frequency furnaces, in particular to a vacuum smelting device for intermediate frequency furnaces. Background technique [0002] Vacuum intermediate frequency furnace is a periodic operation type electric furnace, which is widely used in sintering treatment of cemented carbide, superalloy, photoelectric materials, functional ceramics, transparent ceramics, powder metallurgy, etc. under high temperature, high vacuum and protective atmosphere conditions. At the same time, it is also suitable for powder forming and sintering of refractory alloys such as tungsten, molybdenum and their alloys in scientific research, military units and industrial units. [0003] The existing traditional vacuum intermediate frequency furnace consists of a mold cavity, a medium vacuum gauge, a low vacuum gauge, a high vacuum valve, a Roots pump, an oil diffusion pump, a backing vacuum pump, a low vacuum valve, etc., ...

AI Technical Summary

Problems solved by technology

This type of vacuum intermediate frequency furnace has the disadvantages of complex structure, low pumping efficiency and high energy consumption, and the vacuum gauges of existing vacuum intermediate frequency furnaces are mostly located in the furnace body. In the long-term high temperature environment, the service life of the vacuum gauge is greatly shortened. We need to propose a vacuum smelting device for intermediate frequency furnace
