Specific implementation mode
It is illustrated with reference to specific embodiment：
It is furnished with load coil 1 in the periphery of casting package 1,18 (steel of metal charge can be directly loadable into casting package
Water or steel scrap), heating and thermal insulation, alloying component adjustment etc. are then carried out to the metal charge in casting package by load coil
At the same time top slag 19 can be added in reason on the molten steel face in packet, play the role of absorption and be mingled with, keep the temperature, preventing secondary oxidation.
The load coil of casting package periphery uses the mode of heating of power frequency, can generate good mixing power to the molten steel in casting package
Effect makes molten steel come into full contact with the metallurgy action that can more preferably play top slag with top slag.In casting package the ingredient of molten steel and
When temperature reaches the target of tapping, molten steel is discharged into crystallizer by the molten steel delivery pipe 2 for being arranged in casting package bottom.By
In in order to keep, molten steel can fully complete wash heat in water mold 5 and solidification completely reaches the effect of traditional electroslag remelting
Fruit, in molten steel spill process flow and inflow mode control it is most important.In order to enable the small stability of flow dispersion of molten steel
Ground is flowed into water mold, while preventing from freezing due to the too small solidification during outflow of molten steel flow again, to molten steel
Delivery pipe 2 has carried out following design：Molten steel delivery pipe 2 is by extraction slide plate 16, drainage channel 15, cushion chamber 14, shunting circumferential weld 13
It is formed with the load coil 23 for being arranged in its periphery.Wherein, the top that slide plate 16 is arranged in drainage channel 15 is drawn, it can
The molten steel amount for flowing into drainage channel 15 is controlled to draw the aperture of slide plate 16 by control, is equipped in the lower end of drainage channel 15
Cushion chamber 14 is provided with discontinuous in the edge of 14 bottom of cushion chamber and shunts circumferential weld 13.After molten steel reaches tapping requirement, beat
Open draw slide plate 16 molten steel in casting package 1 is introduced by drainage channel 15 in cushion chamber 14, later molten steel again by with
The discontinuous shunting circumferential weld 13 that 14 bottom of cushion chamber is connected is flowed into water mold, and molten steel enters shunting in order to prevent
Cooling is freezed after circumferential weld, and the periphery that circumferential weld 13 is shunted in discontinuous is equipped with high-frequency induction heating coil.It is set in the lower part of casting package 1
There is infundibulate water mold 5, is slag bath 12 on the top of crystallizer, in order to make the refining slag of slag bath be in high-temperature fusion shape
State is equipped with slag heating electrode 4 in slag bath.Although the molten steel in casting package 1 can be enable with small by molten steel delivery pipe 2
The form of flow dispersion is flowed into water mold 5, but cannot reach female electrode melting in traditional esr process
At the effect that molten steel drips, female electrode melting speed in traditional esr process is also far above despite small flow, this will
Cause the molten steel flowed into that cannot fully be reacted with the refining slag in slag bath 12, it is difficult to reach last refining effect.While with
The molten steel amount of inflow increases, it is desirable that the setting rate in water mold will also improve under the premise of ensuring quality under guarantee
Portion's metal pool 7 has stable liquid level.For this purpose, the degree of superheat for flowing into molten steel in metal pool 7 will be reduced, in order to reach this mesh
, it is equipped with magnetic stirrer 6 in the middle and lower part of slag bath, the molten steel in slag bath can be stirred, under the action of mixing power
The molten steel of inflow is torn into droplet, to play the effect that can be fully reacted with refining slag, while can also play drop
The effect of superheat of liquid steel in low metal pond 7, can achieve the effect that traditional electroslag remelting.In casting process, the liquid of metal pool
Face cannot be excessively high, if being higher than the expanding position of crystallizer, will certainly lead to card billet, is equipped with thus in the outside of water mold
Liquid level sensor 11, to monitor the situation of change of metal bath liquid level, when the liquid level of metal bath 7 is less than setting liquid level
When, increase the aperture for drawing slide plate 16；When the liquid level of metal bath 7 is higher than setting liquid level, reduces and draw slide plate 16
Aperture makes the aperture of extraction slide plate 16 reach dynamic auto adjustment, to keep the stabilization of 7 liquid level of metal bath.It is crystallized in water cooling
The bottom of device is equipped with the Dummy plate 9 of internal water flowing cooling, the bottom for blocking water mold in initial period.
The pulling rolls 8 for drawing billet 10 can be also equipped in the outside of the lower part of Dummy plate 9, it is dynamic accordingly in order to complete
Make, pulling rolls 8 are connected with hydraulic cylinder 20 and motor 21, wherein hydraulic cylinder 20 can complete pulling rolls 8 to the compression of billet 10 with
Relieving acts, and motor 21 can complete the action of the drawing to billet 10.It is less than or equal to water if it is the billet length direction of production
The steel ingot of chamber size in cooling crystallizer, then Dummy plate only serve the effect of closure；If the billet length direction of production is more than water
Chamber size in cooling crystallizer then can be by it slowly after then the molten steel Yu Dummy plate of bottom are freezing together in water mold
It pulls out, the pulling rolls 8 being arranged later in the lower outside of Dummy plate 9 start to act, and start hydraulic cylinder 20 first and press pulling rolls 8
On billet, then starts motor 21 and drawing is carried out to billet 10.
