Description
Technical field
The utility model relates to a kind of vacuum high temperature furnace heater.
Background technology
The vacuum high temperature furnace heater is installed in the vacuum furnace heating chamber, connects with water cooled electrode, as the heater members of vacuum resistance furnace.The vacuum high temperature furnace heater can be made single-phase, three-phase star, three-phase double star, three-phase asterism structure by the power difference.
Common vacuum high temperature furnace heater; Comprise that ring, tungsten outer shroud, an end are arranged on some heating net sheets and some ejectors that is arranged on the heating net sheet other end between interior ring of tungsten and the tungsten outer shroud in the tungsten; Ejector comprises a tungsten arc-like sheet, a pair of symmetrically arranged tungsten lead-out tablet; The arc-like sheet both sides are respectively arranged with bending edges, and the tungsten lead-out tablet comprises the segmental arc of drawing straight section and matching with the tungsten arc-like sheet, and heating net sheet end is arranged between the segmental arc of tungsten arc-like sheet and tungsten lead-out tablet.The deficiency of its existence is: be not suitable for 2200 ℃-2600 ℃ superhigh temperature vacuum furnace, the back thermal deformation that heats up is bigger, and the temperature homogeneity in the stove is had considerable influence, and the easy and heating chamber short circuit in distortion back, causes equipment fault.
The utility model content
The utility model technical problem to be solved is: a kind of long service life is provided, heat distortion amount is little and distortion evenly, can be used for the vacuum high temperature furnace heater under the hyperthermal environments.
For addressing the above problem; The technical scheme that the utility model adopts is: a kind of vacuum high temperature furnace heater; Comprise that ring, tungsten outer shroud, an end are arranged on some heating net sheets and some ejectors that is arranged on the heating net sheet other end between interior ring of tungsten and the tungsten outer shroud in the tungsten; Ejector comprises a tungsten arc-like sheet, a pair of symmetrically arranged tungsten lead-out tablet, and tungsten arc-like sheet both sides are respectively arranged with bending edges, and the tungsten lead-out tablet comprises the segmental arc of drawing straight section and matching with the tungsten arc-like sheet; The straight section of drawing of every pair of tungsten lead-out tablet interconnects; Heating net sheet end is arranged between the segmental arc of tungsten arc-like sheet and tungsten lead-out tablet, and said heating net sheet adopts the tungsten aluminium wire of diameter 0.8-1.2 millimeter to turn to spring-like, again through being compiled into net after the vacuum heat typing.
Drawing of every pair of tungsten lead-out tablet also is provided with stiffener between straight section.
The sweep of described tungsten lead-out tablet, stiffener adopts radius bend at the fillet bending and forming more than 5 millimeters.
Need guarantee that all the tungsten aluminium wires on the heating net sheet all exceed welding position 3-5 millimeter during the outer loops welded of ring in described heating net sheet and tungsten lead-out tablet, tungsten arc-like sheet and the tungsten, tungsten.
Described ejector quantity is 6.
The beneficial effect of the utility model is: because the heating net sheet adopts the tungsten aluminium wire of diameter 0.8-1.2 millimeter to turn to spring-like; Again through being compiled into net after the vacuum heat typing; The heating net sheet is more smooth, and more stable through structure after the hot pressing of heating, and has guaranteed no rosin joint during welding and has leaked weldering.
Because the sweep of tungsten lead-out tablet, stiffener adopts big fillet bending and forming, has reduced the crackle generation.
Owing to adopt some heating net sheets 3 to substitute whole heating net sheet; Online stressed even when having guaranteed high temperature, thus efficiently solve under superhigh temperature, the high vacuum environment, and heater is not long useful life; Heat distortion amount big and be out of shape inhomogeneous, can't permanently effective work problem.
