[0002] The diameters, lengths, and weights of graphite electrodes in large-sized titanium slag electric furnaces are relatively large. The perpendicularity of the electrode brakes of graphite electrodes is very important for the pressing process of graphite electrodes. If there is a deviation in the perpendicularity of the brakes, it is easy for the graphite electrode to break and fall into the electric furnace after being clamped, resulting in the shutdown of the electric furnace. Moreover, each time it takes a long time to handle the failure of graphite electrode breakage, the labor intensity of maintenance workers is high, which affects the output of titanium slag. And the failure of graphite electrode breakage will greatly reduce the operation rate of the electric furnace, require additional maintenance time, increase the labor intensity of maintenance personnel, further reduce the output of titanium slag in the electric furnace, thus causing losses to economic and social benefits.

[0026] As Figure 1 , Figure 2 As shown in

[0027] Specifically, the inner side of the brake shoe 2 contacting the graphite electrode 1 means that the brake shoe 2 contacts one surface of the outer peripheral vertical surface of the graphite electrode 1, and after the pressing part applies pressure to the brake shoe 2, the brake shoe 2 clamps the graphite electrode 1. Among them, the outer side of the brake shoe 2 contacting the pressing part means that the pressing part is connected to the outer side of the brake shoe 2, and when pressure is applied to the pressing part, the pressure is transmitted to the brake shoe 2.

[0028] Specifically, after the pressing part applies pressure to the brake shoe 2, the pressure is transmitted from the pressing part to the brake shoe 2, and through the graphite electrode 1 in contact with the brake shoe 2, acts on the graphite electrode 1. Thus, a force acting from the outer surface to the inside is applied to the inner surface of the graphite electrode 1 where the brake shoe 2 contacts the graphite electrode 1, so that the perpendicularity adjustment of the contact position between the inner side of the brake shoe 2 and the graphite electrode 1 is completed under the action of the force.

[0029] Through the above technical solution, the present disclosure provides a device and method for adjusting the verticality of a graphite electrode. The device for adjusting the verticality of the graphite electrode includes: a graphite electrode, a brake shoe, and a pressing part. The inner side of the brake shoe is in contact with the graphite electrode, and the outer side of the brake shoe is in contact with the pressing part. Among them, the pressing part applies pressure to the brake shoe to make the brake shoe hold the graphite electrode tightly. In this process, by applying pressure to the brake shoe through the pressing part, under the action of the applied pressure, the brake shoe fits the graphite electrode, and the verticality of the graphite electrode is adjusted under the action of the brake shoe, thereby reducing the risk of the graphite electrode breaking after being held tightly, effectively reducing the fault of the graphite electrode breaking, improving the operation rate of the electric furnace, reducing the maintenance time, reducing the labor intensity of the maintenance personnel, increasing the output of titanium slag in the electric furnace, and thus creating greater economic and social benefits.

[0030] In some alternative embodiments, the inner side of the brake shoe 2 is in contact with one surface of the outer peripheral vertical surface of the graphite electrode 1.

[0031] Specifically, the outer peripheral vertical surface of the graphite electrode 1 refers to the outer surface of the graphite electrode 1 in the direction perpendicular to the ground. Among them, the shape of the graphite electrode 1 can be set according to the actual working conditions, and this embodiment does not make specific limitations on this. For example, when the graphite electrode 1 is square in the top view, the outer peripheral vertical surface of the graphite electrode 1 refers to the four outer vertical surfaces of the graphite electrode 1 perpendicular to the ground; similarly, it can be known that if the graphite electrode 1 is hexagonal in the top view, the outer peripheral vertical surface of the graphite electrode 1 refers to the six outer vertical surfaces of the graphite electrode 1 perpendicular to the ground, and so on, without further elaboration.

[0032] In some alternative embodiments, the brake shoe 2 and the corresponding pressing part are used in groups, and the opposite surfaces of the outer peripheral vertical surface of the graphite electrode 1 both have the corresponding brake shoe 2 and pressing part used in groups.

[0033] Specifically, the brake shoe 2 and the corresponding pressing part being used in groups means that on the outer side of each brake shoe 2 in contact with the outer peripheral vertical surface of the graphite electrode 1, there is a corresponding pressing part, so that the corresponding pressing part can apply pressure to the brake shoe 2 to make the brake shoe 2 on this surface hold the graphite electrode 1 on the corresponding surface tightly.

[0034] Specifically, the opposite faces of the outer peripheral vertical surface of the graphite electrode 1 each have a corresponding set of brake shoes 2 and pressing parts. This means that on the outer peripheral vertical surface of the graphite electrode 1, there are brake shoes 2 arranged oppositely, and pressing parts corresponding to the brake shoes 2, so that the pressing parts apply pressure to the brake shoes 2, thereby applying a force acting from the outer surface to the inside on each of the opposite outer peripheral vertical surfaces of the graphite electrode 1. And because the brake shoes 2 are arranged at the opposite positions on the outer peripheral vertical surface of the graphite electrode 1, each applied force acts on the inside of the graphite electrode 1, and the directions of the forces are opposite, making the adjustment of the perpendicularity of the graphite electrode more obvious compared to the force applied on a single side, so that the perpendicularity adjustment at the contact position between the inner side of the brake shoe 2 and the graphite electrode 1 is completed under the action of the force. For example, if the graphite electrode 1 is a cuboid, and the top surface of the graphite electrode 1 is a quadrilateral in the top-down view, clockwise in sequence are a, b, c, d, then at this time the opposite faces of the outer peripheral vertical surface of the graphite electrode 1 are a, c or b, d; similarly, it can be known that if the top surface of the graphite electrode 1 is a hexagon in the top-down view, clockwise in sequence are a, b, c, d, e, f, then at this time the opposite faces of the outer peripheral vertical surface of the graphite electrode 1 are a, d or b, e or c, f or a, c, e or b, d, f, and so on, without further elaboration.

[0035] In some alternative embodiments, the brake shoes 2 and the corresponding pressing parts are used in groups, and each outer peripheral vertical surface of the graphite electrode 1 has a corresponding set of brake shoes 2 and pressing parts.

[0036] Specifically, the fact that each outer peripheral vertical surface of the graphite electrode 1 has a corresponding set of brake shoes 2 and pressing parts means that on each surface of the outer peripheral vertical surface of the graphite electrode 1, there are brake shoes 2 arranged, and pressing parts corresponding to the brake shoes 2, so that the pressing parts apply pressure to the brake shoes 2, thereby applying a force acting from the outer surface to the inside on each outer peripheral vertical surface of the graphite electrode 1. And because the brake shoes 2 are arranged on each surface of the outer peripheral vertical surface of the graphite electrode 1, each applied force acts on the inside of the graphite electrode 1, making the adjustment of the perpendicularity of the graphite electrode more obvious compared to the force applied on a single side or opposite sides, so that the perpendicularity adjustment at the contact position between the inner side of the brake shoe 2 and the graphite electrode 1 is completed under the action of the force.

[0037] In some alternative embodiments, the brake shoe 2 has at least one groove, and the pressing part includes at least one top block 4, and the top block 4 is fitted into the groove.

[0038] Specifically, as Figure 1 、 Figure 2As shown, the brake shoe 2 has at least one groove, and the pressing part includes at least one top block 4. Among them, the top block 4 is fitted into the groove. When the pressing part applies pressure to the brake shoe 2, the force is conducted to the brake shoe 2 through the fitted groove by at least one top block 4, so that the brake shoe 2 holds the graphite electrode 1 tightly. It should be understood that the number of grooves of the brake shoe 2 and the top block 4 includes but is not limited to those shown in the figure. As long as the top block 4 is fitted into the groove and is used to conduct the force through the fitted top block 4 and groove. And when the number of grooves and top blocks 4 is multiple, the forces acting on the graphite electrode 1 from the outer surface to the inside by the brake shoe 2 should also be multiple, so that the adjustment of the verticality of the graphite electrode at this position is more obvious than the force applied by the fitting of one groove and top block, and thus the verticality adjustment of the contact position between the inner side of the brake shoe 2 and the graphite electrode 1 is completed under the action of the force.

[0039] In some alternative embodiments, at least one groove is a circular groove, and at least one top block 4 is a circular top block.

[0040] Specifically, as Figure 1 、 Figure 2 shown, at least one groove is a circular groove, and the corresponding top block 4 is a circular top block. It should be understood that the groove can also be a square groove or a groove of other shapes, and the corresponding top block can be a square top block or a top block of other shapes. This embodiment does not make specific limitations on this and can be set according to the actual working conditions.

[0041] Specifically, when at least one groove is a circular groove and at least one top block 4 is a circular top block, in subsequent embodiments, the brake shoe 2 is more conducive to sliding along the outer peripheral vertical surface of the graphite electrode 1 under the action of the pressing part. Therefore, generally, the groove is selected as a circular groove and the top block 4 is a circular top block.

[0042] In some alternative embodiments, the pressing part further includes: a pressing plate 3 and a connecting screw 5. Among them, the pressing plate 3 is used to fix at least one top block 4, and the connecting screw 5 is used to apply pressure to the brake shoe 2 through the connecting screw 5.

[0043] Specifically, as Figure 1 、 Figure 2 shown, the pressing plate 3 is used to fix at least one top block 4 to ensure the fitting degree of the top block 4 and the corresponding groove, and to prevent the top block 4 from sliding in the corresponding groove without external force.

[0044] Specifically, the connecting screw 5 is connected to the top block 4, and the setting of the connecting screw 5 facilitates the pressing part to apply pressure to the brake shoe 2.

[0045] In some alternative embodiments, the brake shoe 2 is also used to slide along the outer peripheral vertical surface of the graphite electrode 1 under the action of the pressing part.

[0046] Specifically, the sliding of the brake shoe 2 along the outer peripheral vertical surface of the graphite electrode 1 means that the brake shoe 2 slides from one end of the graphite electrode 1 to the other end, and during this process, the pressing part keeps applying pressure to the brake shoe 2, so as to complete the perpendicularity adjustment of each position from one end of the graphite electrode 1 to the other end, that is, to complete the perpendicularity adjustment of the whole graphite electrode 1.

[0047] According to an embodiment of the present invention, a method for adjusting the perpendicularity of a slag graphite electrode is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in a different order than here.

[0048] This embodiment provides a method for adjusting the perpendicularity of a graphite electrode, as Figure 3 shown, the method includes the following steps: S101. In response to the graphite electrode perpendicularity adjustment instruction, install the brake shoe and the pressing part at one end of the graphite electrode to determine the installation position.

[0049] Specifically, installing the brake shoe and the pressing part at one end of the graphite electrode to determine the installation position means installing the brake shoe and the pressing part at one end of the outer peripheral vertical surface of the graphite electrode, such as the top end or the bottom end, and using the corresponding position as the installation position. Among them, the brake shoe and the corresponding pressing part are used in groups, and the installation position includes one surface, the opposite surface or each surface in the outer peripheral vertical surface of the graphite electrode. For specific details, please refer to the relevant description of the above embodiment, and will not be elaborated here.

[0051] Specifically, based on the installation position, through the pressing part and the brake shoe, making the brake shoe hold the graphite electrode tightly means applying pressure from the pressing part to the brake shoe at the installation position, so that the brake shoe holds the graphite electrode tightly. For specific details, please refer to the relevant description of the above embodiment, and will not be elaborated here.

[0052] Through the above technical solutions, the present disclosure provides a device and a method for adjusting the verticality of a graphite electrode.

In this process, pressure is applied to the brake shoe through the pressing part, so that under the action of the applied pressure, the brake shoe fits the graphite electrode, and the verticality adjustment of the graphite electrode is completed under the action of the brake shoe, thereby reducing the risk of the graphite electrode breaking after being held tightly, effectively reducing the graphite electrode breakage fault, improving the operation rate of the electric furnace, reducing the maintenance time, reducing the labor intensity of the maintenance personnel, increasing the titanium slag output of the electric furnace, and thus creating greater economic and social benefits.
