After the metal droplets are cleaned by the slag liquid, they are crystallized into an electroslag ingot in a water-cooled mold. The bottom conductive connection device of the electroslag furnace is a device used to control the on-off of the electroslag furnace circuit.

[0003] The existing bottom conductive connection device of the electroslag furnace consists of a bottom clamping motor, a speed reducer, a bottom conductive copper plate and a U-shaped copper plate. When it is energized, the bottom clamping motor and the speed reducer rotate to push the bottom conductive copper plate upward to contact the U-shaped copper plate for power connection. The horizontal end of the bottom conductive copper plate is relatively small compared with that of the U-shaped copper plate, and it is impossible to ensure the stability of the pressure between the two. Over time, the horizontal end of the U-shaped copper plate is easily pressed and sunken and deformed by the bottom conductive copper plate, causing potential safety hazards.

[0004] Therefore, there is an urgent need for a new type of bottom conductive connection device for an electroslag furnace to eliminate the hidden danger that the horizontal end of the U-shaped copper plate is easily pressed and sunken by the bottom conductive copper plate.

[0021] Please refer to Figure 1 , the present utility model requests to disclose an electro-slag furnace bottom conductive connection device, which includes a support frame, a cylinder 1, a copper plate, and a cable 4. The cylinder body of the cylinder 1 is installed on the support frame, and the piston rod is horizontally arranged. The copper plate includes a vertical plate 2 and a horizontal plate 3. The vertical plate 2 and the horizontal plate 3 are electrically connected and fixedly connected. One side in the thickness direction of the vertical plate 2 faces the conductive component at the bottom of the electro-slag furnace, and the other side is fixedly connected to the end of the piston rod of the cylinder 1, so that the cylinder 1 can push the vertical plate 2 to contact and electrically connect with the conductive component at the bottom of the electro-slag furnace, or separate from the conductive component at the bottom of the electro-slag furnace. One end of the cable 4 is electrically connected to the horizontal plate 3, and the other end is electrically connected to an external power source.

[0022] When the electro-slag furnace needs to be powered on, the piston rod of the cylinder 1 extends, pushing the vertical plate 2 to contact the conductive component at the bottom of the electro-slag furnace, and the electro-slag furnace is powered on.

[0023] Specifically, the support frame can be a structure of various shapes that can play a stable supporting role. In this embodiment, please refer to Figure 1, the support frame includes a frame body and a sliding component. The frame body includes a mounting rod 5 and a connecting rod 6. The number of mounting rods 5 is two, and the two connecting rods 6 are both parallel to the telescopic direction of the piston rod of the cylinder 1. The two mounting rods 5 are respectively connected to both ends of the connecting rod 6 and are located on the same side of the connecting rod 6, so that the frame body is in a C shape. The frame body is horizontally arranged through four feet 7.

[0024] The support frame further includes a mounting plate 8. The mounting plate 8 is horizontally on the frame body and is located between the two mounting rods 5 and is fixedly connected to both mounting rods 5. The mounting plate 8 is used for mounting the cylinder block of the cylinder 1.

[0025] The function of the sliding component is to define the sliding direction of the vertical plate 2 and avoid the occurrence of poor contact caused by deviation of the sliding direction of the vertical plate 2.

[0026] The sliding component includes a slide rail 9, a sliding frame 10 and a connecting piece 11. The number of slide rails 9 is two, and the two slide rails 9 are parallel to each other and are respectively fixedly connected to two opposite side surfaces of the two mounting rods 5. The sliding frame 10 is in the shape of a rectangular plate. Rollers 12 are installed on two opposite side surfaces of the sliding frame 10 in the horizontal direction. The sliding frame 10 is installed on the two mounting rods 5 by installing the rollers 12 on both sides thereof respectively. The sliding frame 10 is located below the mounting plate 8.

[0027] The connecting piece 11 is in the shape of a plate. One side in the thickness direction thereof is fixedly connected to the end of the piston rod of the cylinder 1, and the other side is fixedly connected to the vertical plate 2. The lower side of the connecting plate is fixedly connected to the sliding frame 10

[0028] When the piston rod of the cylinder 1 extends, it pushes the sliding frame 10 to move on the slide rail 9, and then drives the connecting piece 11 to move. Finally, by pushing the vertical plate 2, the entire copper plate contacts and electrically connects to the conductive component at the bottom of the electroslag furnace.

[0029] The horizontal plate 3 of the copper plate can be electrically connected to the cable 4 by a direct connection method. However, in this direct connection method, when the horizontal plate 3 moves with the vertical plate 2, it will pull the cable 4 back and forth, reducing the service life of the cable 4 and the connection joint between the cable 4 and the horizontal plate 3, and there are potential safety hazards. Therefore, in this embodiment, a flexible connection is adopted between the cable 4 and the horizontal plate 3.

[0030] Specifically, brackets 16 are installed on the upper sides of the two mounting rods 5, and a first copper bar 13 is fixedly installed between the two brackets 16. The first copper bar 13 is electrically connected to the cable 4. The first copper bar 13 is located above the cylinder block of the cylinder 1. A second copper bar 14 is fixedly installed on one side of the horizontal plate 3 close to the cable 4. The second copper bar 14 is connected to the first copper bar 13 through a flexible conductor 15, so that when the horizontal plate 3 moves, it will not drive the cable 4 to move together, which is beneficial to ensuring the service life of the cable 4 and its joints and improving the overall safety of the conductive connection device at the bottom of the electroslag furnace.

[0031] More specifically, in this embodiment, the copper plate is a water-cooled copper plate, which can effectively control the temperature of the contact surface between the copper plate and the conductive component at the bottom of the electroslag furnace, and avoid the deformation of the contact surface due to high temperature stress.

[0032] The cable 4 is a water-cooled cable. The water-cooled cable can maintain a relatively low temperature during long-term use. Compared with an ordinary cable 4, using a water-cooled cable can reduce the phenomenon of heat generation and strand breakage caused by the long-term use of the cable 4.

[0033] The bottom conductive connection device of the electroslag furnace of the present utility model further includes a pressure detection device. The pressure detection device is used to detect the pressure of the cylinder 1. The pressure detection device has a recording module, and the recording module is used to record the pressure curve of the cylinder 1.

[0034] By recording the pressure data of the cylinder and drawing the pressure curve of the cylinder, the staff can check and judge the working state of the cylinder on the historical screen showing the cylinder pressure curve.

[0035] The bottom conductive connection device of the electroslag furnace of the present utility model changes the way of electrical connection of the conductive component at the bottom of the electroslag furnace by the method of pushing the copper plate with a horizontally placed cylinder 1. The copper plate contacts the conductive component at the bottom of the electroslag furnace by horizontal movement, and the sliding component is used to limit the moving direction of the copper plate, so that the copper plate is evenly and controllably stressed when contacting the conductive component at the bottom of the electroslag furnace, and is not easily deformed. Furthermore, the copper plate has a long service life. And the contact position of the copper plate is accurate and not easily offset, which is beneficial to reducing power consumption and at the same time reducing potential safety hazards.

[0036] The bottom conductive connection device of the electroslag furnace of the present utility model also adopts a water-cooled copper busbar to avoid the deformation of the contact surface of the copper busbar due to high temperature stress. It also adopts a water-cooled cable to reduce the phenomenon of heat generation and strand breakage caused by the long-term use of the cable 4.

[0037] The above embodiments are only illustrative of the principles and effects of the present utility model, and are not used to limit the present utility model. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present utility model. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present utility model should still be covered by the claims of the present utility model.
