Abstract
The utility model relates to a vacuum arc skull furnace comprising a vacuum melting chamber, a crucible and an electrode tip is positioned inside the vacuum melting chamber; a charging hopper is arranged on the upside of the vacuum melting chamber, a discharge hole of the charging hopper is fixedly connected with an electrode rod with hollow structure; an auger conveyor is arranged inside the charging hopper and the hollow electrode rod; the lower end of the electrode rod is connected with a hollow electrode tip via a grip. The design of the utility model for the electrode rod and electrode tip is in a hollow structure, and the electrode rod and the electrode tip are connected with the discharge hole; the materials can be conveyed to the center of the crucible through the auger conveyor by utilizing the hollow electrode rod as the passage of materials, and the material can reach an ion area directly, therefore the utility model can reduce the diameter of the crucible and reduce heat radiation loss, and can prevent the molten metal surface in the crucible from being impacted by the materials, and avoid the splash of materials, so that the electric arc is stable. In addition, the structure of the utility model is more simple than the prior structure of skull crucible, furthermore, the utility model not only can be applicable for non-consumable vacuum skull crucible, but also can be applicable for consumable vacuum skull crucible.
Description
Technical field
The utility model is a kind of new construction of vacuum arc skull crucible, and it is applicable to non-consumable formula vacuum arc skull crucible, also can be used in consumable formula vacuum arc skull crucible.
Background technology
In the non-consumable formula vacuum arc skull crucible in the middle of using now, outside electrode stem, promptly charging mechanism is vertical respectively with electrode or be obliquely installed above crucible by the adding approach of fusant material.This structure certainly will make the bore of crucible strengthen, and causes thermal radiation loss excessive and power consumption increases.In addition, above-mentioned charging mechanism because far away from crucible, so cause impact to metal melting liquid level in the crucible when reinforced, produces splash when reinforced, influence stablizing of electric arc.
Summary of the invention
The purpose of this utility model provides a kind of new structure of vacuum arc skull crucible, and it can overcome existing shortcoming in the prior art, reduces the heat loss of crucible, prevents the splash of material.
The purpose of this utility model is achieved in that it comprises the vacuum melting chamber, indoor crucible and the electrode tip of being equipped with of vacuum melting, it is characterized in that being equipped with above the working chamber charging hopper, the discharging opening of charging hopper is fixedlyed connected with the electrode stem of hollow structure, in charging hopper and hollow type electrode stem auger conveyor is housed, the lower end of electrode stem is connected with the hollow type electrode tip by a chuck.
The utility model is designed to hollow structure with electrode stem and electrode tip, be connected with the discharging opening of charging hopper, utilize the passage of hollow electrode bar as material, the utility model by auger conveyor material is delivered directly to the center of crucible, and can directes reach ion plasma, so can make the diameter of crucible reduce, reduce heat loss, simultaneously can prevent to add the impact of material, avoid the splash of motlten metal, make electric arc melting stable fusion liquid level in the crucible.Structure of the present utility model in addition is more simple in structure than original skull crucible, and not only can be applied to non-consumable formula vacuum cooling-shell furnace, also can be used for consumable formula vacuum cooling-shell furnace.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The utility model is described in more detail below in conjunction with embodiment and accompanying drawing thereof.
As shown in Figure 1, the 9th, the vacuum melting chamber, at the indoor crucible 7 that is equipped with of vacuum melting, casting pattern 10, top at crucible is equipped with electrode assembly, electrode assembly includes hollow type cathode electrode bar 4, the upper end of electrode stem and charging hopper 1 are rigidly connected, the lower end of electrode stem is fixing with electrode tip 6 by a chuck 5, electrode tip is hollow structure too, electrode tip can be the non-consumable formula electrode that adopts high-melting point metal to make, it also can be the consumable formula electrode of making of smelting metal, for adjusting the position of ion plasma, be provided with rise fall of electrodes system 3, at the center of electrode stem auger conveyor 2 be housed, 11 of top is motor and transmission devices of auger conveyor.As seen from the figure, crucible in the present embodiment 7 adopts is the structure of casting type of going to the bottom, and has casting gate below it, and the crucible bottom 8 that is driven by cylinder is housed, and the bottom is provided with casting die 10, and it is installed on the trailer.
