[0003] Among them, the liquid metal is covered by the slag pool after passing through the slag pool, thereby avoiding the re-oxidation of the metal, playing an anti-oxidation role, so that the electroslag remelting becomes a smelting device with anti-oxidation effect. Moreover, the quality and performance of the ingot produced by electroslag remelting are improved, the plasticity and impact toughness at low temperature, room temperature and high temperature are enhanced, so that the anti-oxidation electroslag remelting device is widely used.

The lower lifting drive device drives the bottom water tank and the lower lifting arm to rise and fall along the lower stand column. The upper lifting drive device drives the upper lifting arm and the chuck to rise and fall along the upper stand column. The chuck is used to fix the self-consuming electrode.

Specifically, the crystallizer 10 includes the consumable electrode 9, the slag pool 11, the metal pool 12, the electroslag ingot 13 and the bottom water tank 14 arranged in sequence according to the circuit flow direction, the consumable electrode 9 is electrically connected with the power supply (not shown in the figure), the power supply, the consumable electrode 9, the slag pool 11, the metal pool 12, the electroslag ingot 13 and the bottom water tank 14 form a loop through the short net conductor, the bottom water tank 14 is provided below the insulating plate 15, and the working principle of the crystallizer 10 is the prior art and will not be described herein. The consumable electrode 9 is in transmission connection with the rotating ring 2, the rotation of the rotating ring 2 can drive the consumable electrode 9 to move up and down, the height of the consumable electrode 9 is locked when the rotating ring 2 is locked, at this time, the relative height of the consumable electrode 9 and the slag pool 11 is constant, and the consumable electrode 9 can be stably melted, when the consumable electrode 9 inserted into the slag pool 11 is completely melted, the rotating ring 2 is unlocked to be able to rotate, at this time, the height of the consumable electrode 9 can be adjusted, and the lower part of the consumable electrode 9 can be reinserted into the slag pool 11.

In the prior art, the relative position of the consumable electrode and the slag pool in height needs to be realized through the common driving of the upper lifting and lowering driving device and the lower lifting and lowering driving device, the price of the driving device itself and the additional power consumption of the driving device in use make the setting of the upper lifting and lowering driving device and the lower lifting and lowering driving device need to provide more economic support, and in turn cause the cost of using the electroslag remelting device to increase greatly, and the economic burden of enterprises is increased.

[0032] In the embodiment, the rotating ring 2 is drivenly connected with the consumable electrode 9, and the locking and rotating of the rotating ring 2 is controlled by the locking mechanism. When the rotating ring 2 is locked and cannot rotate, the height of the consumable electrode 9 is locked, and the relative position of the consumable electrode 9 and the slag pool 11 in height is fixed, so that the consumable electrode 9 can be melted. When the rotating ring 2 is unlocked, the rotating ring 2 can rotate by itself, and the height of the consumable electrode 9 can be changed, so that the consumable electrode 9 can be further inserted into the slag pool 11 for further melting after the lower part of the consumable electrode 9 is melted. Compared with the prior art, the relative position of the consumable electrode 9 and the slag pool 11 in height is adjusted by the cooperation of the rotating ring 2 and the locking mechanism, without additional power consumption, and the setting of the upper lifting and lowering driving device and the lower lifting and lowering driving device in the prior art is cancelled, so that the use cost of the electroslag remelting device can be greatly reduced, and the economic burden of enterprises is reduced.

Specifically, when the consumable electrode 9 inserted into the slag pool 11 is completely melted, the rotating ring 2 is unlocked by sliding the plug 18, and under the action of the gravity of the consumable electrode 9, the gear 6 is driven to rotate clockwise, the gear 6 drives the rotating ring 2 to rotate clockwise, so that the consumable electrode 9 can move downward into the slag pool 11, and when the depth is appropriate, the height of the consumable electrode 9 can be locked by relocking the rotating ring 2, so that the next stage of melting can be carried out.

[0034] The lifting rope 7 is made of insulating material, so that the current on the consumable electrode 9 cannot flow to the lifting rope 7, thereby improving the safety of the equipment.

[0035] Further, the number of rotating rings 2 is two and arranged in front and back direction translation, the two rotating rings 2 are fixedly connected through the connecting piece 3, under the action of the connecting piece 3, the two rotating rings 2 separated from each other form a whole, the connecting piece 3 is fixedly connected with the sides of the two rotating rings 2 away from each other, so that the connecting piece 3 does not occupy the gap between the two rotating rings 2, the connecting piece 3 is coaxially arranged with the rotating ring 2, the shaft center of the connecting piece 3 is rotatably inserted with the support shaft 4 fixedly connected with the support 1, so that the two rotating rings 2 can rotate around the support shaft 4, the lifting rope 7 passes through between the two rotating rings 2, so that the rotating ring 2 does not contact with the lifting rope 7, so that the lifting rope 7 does not hinder the rotation of the rotating ring 2.

[0036] In the embodiment, the plug-in plate 18 is slidingly inserted in the sleeve 17, both ends of the plug-in plate 18 extend to the outside of the sleeve 17, the sleeve 17 is fixedly installed on the support 1, and the sleeve 17 is used to limit the plug-in plate 18, so that the plug-in plate 18 can only slide along the length direction of the sleeve 17.

[0037] In the embodiment, the locking mechanism further comprises an electromagnet 21 fixedly arranged on the support 1 and a flap 20 rotatably arranged on the support 1, the flap 20 is rotatably connected with the support 1 through a rotating shaft 19, the rotating shaft 19 is rotatably inserted with the flap 20 and fixedly connected with the support 1, the flap 20 is adsorbed with the electromagnet 21, the plug-in plate 18 is driven to slide by the flap 20 in the process of electrifying the electromagnet 21 to make the plug-in plate 18 abut against the external teeth 202, and the plug-in plate 18 is reversely slid in the process of deenergizing the electromagnet 21 to make the plug-in plate 18 staggered with the external teeth 202. By arranging the electromagnet 21, the characteristics of electrifying the electromagnet 21 to have magnetism and deenergizing the electromagnet 21 to have no magnetism are used, so that the plug-in plate 18 can abut against the external teeth 202 when the electromagnet 21 is electrified, thereby locking the height of the consumable electrode 9, the plug-in plate 18 can stagger with the external teeth 202 when the electromagnet 21 is deenergized, thereby making the consumable electrode 9 drive the gear 6 and the rotating ring 2 to rotate clockwise under the action of its own gravity, and further making the consumable electrode 9 move downward to insert into the slag pool 11. As can be seen, the relative position of the consumable electrode 9 and the slag pool 11 in height can be controlled by electricity, thereby canceling the manual sliding of the plug-in plate 18.

[0038] Further, reference is made to the accompanying drawings Figure 4 and the accompanying drawings Figure 5The compression spring 16 is connected between the plug plate 18 and the sleeve 17, one end of the compression spring 16 is fixedly connected with the plug plate 18, the other end is fixedly connected with the sleeve 17, the compression spring 16 is always in a compressed state, the plug plate 18 has an action force away from the rotating ring 2 by using the compression elastic force of the compression spring 16, when the action force of the flap 20 on the plug plate 18 disappears, the plug plate 18 is driven to slide under the action of the compression spring 16 to make the plug plate 18 disengage with the external teeth 202, thereby realizing the unlocking of the rotating ring 2, the plug plate 18 and the sleeve 17 are vertically arranged, the top of the left side (referring to the left side of the rotating shaft 19) of the flap 20 is in sliding abutment with the bottom of the plug plate 18, the bottom of the right side (referring to the right side of the rotating shaft 19) of the flap 20 is in adsorption cooperation with the electromagnet 21, the electromagnet 21 is adsorbed with the flap 20 when the electromagnet 21 is powered on to make the flap 20 drive the plug plate 18 to abut against the external teeth 202, the compression elastic force of the compression spring 16 is greater than the sliding friction force generated when the plug plate 18 abuts against the external teeth 202, the plug plate 18 slides downward to disengage with the external teeth 202 under the action of the compression spring 16 when the electromagnet 21 is powered off, the adsorption force between the electromagnet 21 and the flap 20 is greater than the compression elastic force of the compression spring 16. Specifically, when the electromagnet 21 is powered on, the bottom of the right side of the flap 20 is adsorbed with the electromagnet 21, the left side of the flap 20 is turned upward under the action of the adsorption force to drive the flap 20 to lift the plug plate 18 upward to abut against the external teeth 202, thereby realizing the locking of the rotating ring 2; when the electromagnet 21 is powered off, the plug plate 18 drives the flap 20 to press downward the top of the left side of the flap 20 under the action of the elastic force of the compression spring 16 to make the left side of the flap 20 turn downward, at the same time, the plug plate 18 disengages with the external teeth 202 to unlock the rotating ring 2.

[0039] Further, the bracket 1 is fixedly provided with a fixed plate 101 above the right side of the flap 20, the fixed plate 101 abuts against the top of the right side of the flap 20 when the plug plate 18 disengages with the external teeth 202 to control the distance between the flap 20 and the electromagnet 21, thereby ensuring that the flap 20 can be quickly adsorbed with the electromagnet 21 when the electromagnet 21 is powered on.

[0040] In the embodiment, the current flowing into the electromagnet 21 and the current flowing into the consumable electrode 9 come from the same power source, thereby when the electromagnet 21 is powered on, no additional power supply equipment is needed, no additional electricity cost is caused, the present application can realize the continuous melting of the consumable electrode 9 by driving the consumable electrode 9 to move downward without using other electric energy, thereby no cost is increased when the electric-shock remelting device is used.

[0041] Wherein, the electromagnet 21 is connected in series in the circuit between the power supply and the consumable electrode 9, so that the electromagnet 21 is turned on when the consumable electrode 9 is inserted into the slag pool 11, at this time the rotating ring 2 is locked, so that the consumable electrode 9 is locked in height, thereby high-temperature melting in the slag pool 11, since the consumable electrode 9 is completely melted and separated from the liquid surface of the slag pool 11, at this time the consumable electrode 9 is disconnected from the loop formed by the crystallizer 10 and the power supply, so that no current flows to the electromagnet 21, that is, after the consumable electrode 9 inserted into the slag pool 11 is completely melted, the consumable electrode 9 is separated from the slag pool 11 to make the electromagnet 21 lose power, under the action of the compression spring 16, the plug plate 18 is driven to be misaligned with the outer tooth 202 which is originally abutted, at this time the rotating ring 2 is unlocked and rotates clockwise under the action of the gravity of the consumable electrode 9, so that the consumable electrode 9 moves downward by a distance and re-enters the slag pool 11, thereby the loop formed by the consumable electrode 9, the crystallizer 10 and the power supply is re-connected, so that the electromagnet 21 is re-powered, the electromagnet 21 after being powered drives the plug plate 23 to abut with the next outer tooth 202, so that the rotating ring 2 is re-locked, so that the height of the consumable electrode 9 is locked again to melt in the next stage, and so on, so that the consumable electrode 9 can continuously and automatically move downward until the consumable electrode 9 is completely melted, and the consumable electrode 9 is moved downward without human operation throughout the process.

[0042] Therefore, the application creatively uses the current in the loop formed by the consumable electrode 9, the crystallizer 10 and the power supply, and fully utilizes the power-off characteristics of the consumable electrode 9 in the process of being continuously melted, so that the application has unexpected technical effects, that is, the consumable electrode 9 inserted into the slag pool 11 can automatically move downward by a distance and re-enter the slag pool 11 to continue melting after being completely melted, so that the consumable electrode 9 can completely and automatically melt throughout the process without any additional power consumption and human consumption throughout the process.

[0043] Wherein, the hanging rope 7 has elasticity, the elasticity of the hanging rope 7 does not need to be too large, which is easy to cause the consumable electrode 9 to shake, only needs to be able to pull the consumable electrode 9 upward by a distance after the part of the consumable electrode 9 inserted into the slag pool 11 is completely melted (because the weight of the consumable electrode 9 is reduced after the part of the consumable electrode 9 inserted into the slag pool 11 is completely melted, so that the consumable electrode 9 is pulled upward), the length of the distance is not less than 0.5 mm, so as to ensure that the part of the consumable electrode 9 inserted into the slag pool 11 can be completely separated from the slag pool 11 after being completely melted, so that the loop formed by the consumable electrode 9, the crystallizer 10 and the power supply is completely powered off, so that the electromagnet 21 completely loses magnetism, and finally the consumable electrode 9 moves downward.

[0044] The foregoing merely illustrates some exemplary embodiments of the application, and no doubt numerous modifications and alterations thereto will be apparent to those skilled in the art. Accordingly, the above description is intended for purposes of illustration only and should not be construed as limiting the scope of the application.
