Description
Technical field
The utility model belongs to metal electroslag remelting equipment technical field, is related to a kind of electromagnetic stirring mould.
Background technique
Electroslag furnace is that the resistance heat generated when passing through slag using electric current carries out a kind of metallurgical equipment of melting as heat source.
The steel smelted through electroslag furnace has purity is high, sulfur content is low, non-metallic inclusion is few, surface of steel ingot is smooth, crystallization is uniform to cause
Close, metallographic structure and the uniform advantage of chemical component.Therefore, at home and abroad the industries such as steel, machinery obtain electroslag furnace apparatus
It is widely applied.
Crystallizer used in electroslag furnace apparatus is when working smelting, due to dropping onto the gold of the liquid in crystallizer from smelting furnace
Belonging to liquid is vertical drop, when drips into crystallizer or lower section on the steel ingot of formed solid when, be similar to water
The same liquid that can also splash is spent to spend, the centre of final steel ingot can be to lower recess, and surrounding opposite can be lifted, and molten bath be formed, to product
Quality produce certain negative effect.
Utility model content
The purpose of this utility model is to generate thick and solid molten bath for existing crystallizer for electroslag furnace and then lead to product
Problem of low quality, and a kind of electromagnetic stirring mould proposed.
The purpose of this utility model can be realized by the following technical scheme:
A kind of electromagnetic stirring mould, the ontology including corresponding up and down with smelting furnace and relatively fixed setting, the interior tool of ontology
Have for the cavity for collecting drippage molten metal, which is characterized in that the sheet is also encompassed in vitro equipped with an eccentric cylinder, eccentric
Uniformly coiling has coil on the inner wall of cylinder, and the both ends of coil are connect with a power supply part, and the bottom of eccentric cylinder passes through shaft and one
Driving part connection, distortion of the shaft relative to eccentric cylinder.
In a kind of above-mentioned electromagnetic stirring mould, the ontology is cylindrical, and the central axes of ontology and shaft are same
Axis.
It is penetrating on the bias drum outer wall to offer a through-hole, power supply in a kind of above-mentioned electromagnetic stirring mould
Part is installed on the outer wall of eccentric cylinder, and one end of coil passes through through-hole and a pole of power supply part connects, the other end of coil with
Another pole of power supply part connects.
Compared with prior art, this crystallizer for electroslag furnace is powered by coil generates electromagnetic field, and the center of electromagnetic field
Line part the most intensive meeting period in imaginary circles during eccentric cylinder rotation rotates, can be uniform by metallic solution
The each position being directed on ontology.
Detailed description of the invention
Fig. 1 is the lateral axis side structure schematic diagram of this crystallizer.
Fig. 2 is the overlooking structure diagram of this crystallizer.
Fig. 3 is schematic diagram of internal structure of this crystallizer after clipping a part.
In figure, 1, ontology；2, eccentric cylinder；3, coil；4, shaft；5, driving part；6, through-hole；7, power supply part.
Specific embodiment
It is specific embodiment of the utility model and in conjunction with attached drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these examples.
As shown in Figures 1 to 3, this electromagnetic stirring mould includes the ontology of corresponding up and down with smelting furnace and relatively fixed setting
1, ontology 1 is interior to be had for the cavity for collecting drippage molten metal, and ontology 1 is also encompassed equipped with an eccentric cylinder 2, eccentric cylinder 2 outside
Inner wall on uniformly coiling have coil 3, the both ends of coil 3 connects with a power supply part 7, the bottom of eccentric cylinder 2 pass through shaft 4 and
One driving part 5 connection, distortion of the shaft 4 relative to eccentric cylinder 2, ontology 1 is cylindrical, the central axes of ontology 1 with
Shaft 4 is coaxial, and penetrating on 2 outer wall of eccentric cylinder to offer a through-hole 6, power supply part 7 is installed on the outer wall of eccentric cylinder 2, coil 3
One end pass through through-hole 6 connect with a pole of power supply part 7, the other end of coil 3 is connect with another pole of power supply part 7.
Coil 3 can generate electromagnetic field after being powered, and the origin of the molten metal to drop down from smelting furnace is metal, so it
During the falling process can cutting magnetic field, produce the effect of stirring to a certain extent.
It was hindered under molten drop before this moreover, because magnetic direction is practical, and the effect hindered gradually dies down, then again
Under assistant metal drop, and the effect assisted also come it is stronger, so falling speed also can be slower during preamble for molten metal, and
The position finally dripped has powerful electromagnetic attraction, so be not easy to sputter liquid flower, so that obtained texture is thinner,
Molten bath is also more shallow.
In the design, continuous eccentric turnover of the eccentric cylinder 2 relative to 1 central axis of ontology, in order to allow magnetic field
Centerline portion --- the position of the namely thick in magnetic field constantly changes, because this virtual center line is actually
Coil 3 generates electromagnetic field part the most apparent, and molten metal can drip gradually downward in the case where the direction of this center line guides, and
Due to the turnover of eccentric cylinder 2, center line can also carry out period turnover in an imaginary circles, it is possible to think, the gold to drip
The motion profile for belonging to liquid is physically close to a virtual spiral shape, and the position that molten metal finally drips, and can be in center
In the imaginary circles that line motion profile is formed, this molten metal final position that different times will also dripped is in 1 bottom surface of ontology
Or the different location of molding surface of steel ingot, make the branch of molten metal more uniform, the product quality effect of generation is also just more preferably.
