The described vacuum tank with the vacuum tegillum for electric-arc heating vacuum-treat refining furnace is characterized in that: also comprise and leak the hilllock net, the bottom of vacuum tank is the prone truncated cone-shaped of handle, and vacuum tank truncated cone-shaped bottom is provided with the bleed-out net.
When the utility model uses:
Make the jacking unscrewing device that the vacuum tegillum is gone to rear decline the in vacuum tegillum seat top, make the little cage of vacuum tegillum and vacuum close up sealing; Make vacuum container cover decline and vacuum tank close up sealing; Formed so an airtight vacuum chamber, the pump-line of vacuum pump by vacuum tank one side vacuumizes and can carry out vacuum treatment.
Make the jacking unscrewing device with vacuum tegillum jacking rotary °, expose the casting material small furnace cover that has three electrode holes in the little cage of vacuum, make rotatable electrode rotary to processing the station center, electrode descends and three electrode holes by the casting material small furnace cover enter vacuum tank inside can carry out heating operation near liquid steel level.
Viewing window is closed when implementing vacuum treatment, can be opened when implementing heating operation in order to observe, feed in raw material and thermometric.
Bearing is used for being connected with vacuum feeding device, and when implementing heating operation, the valve of vacuum feeding device is all opened, and only uses as the transition feeding chute.
The beneficial effects of the utility model are:
(1) save non-cutting time, the haulage time from the heating operation to the vacuum treatment, handling time, furnace cover lifting time are all shortened, and refining cycle shortens;
(2) realized heating under the prerequisite that vacuum container cover is not opened, the extraneous factor of inhaling hydrogen improves;
(3) because ladle heats in vacuum tank, can reduce the heat radiation of ladle, improved heating efficiency;
(4) terminal temperature can suitably reduce, and can reduce heat-up time, has energy-saving effect.
