[0003] Since the slag and iron eyes of titanium slag electric furnace are deeper than those of other alloy electric furnaces, it is difficult for traditional eye-opening and plugging machines to meet the eye-opening accuracy requirements. The eye-opening accuracy is not accurate enough. For example, if the slag eye is opened too high, the liquid level in the furnace will be too low, the pressure will be low, and the slag flow rate will be reduced, which will directly affect the output and waste electricity; if the slag eye is opened too low, the output of a single furnace will increase on the surface, but it is very unfavorable to the furnace condition, causing the iron temperature to rise, and it is extremely cumbersome to adjust the furnace condition in the later stage; if the iron eye is opened too high, slag will come out of the iron eye, and the eye needs to be plugged immediately. After cooling, the eye needs to be reopened, affecting the overall smelting time; if the iron eye is opened too low, the iron output will be too much, causing high-temperature damage to the cast iron machine.

DETAILED DESCRIPTION
[0021] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0022] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.
[0023] like Figure 1-Figure 3 As shown, a high-precision electric arc furnace eye-blocking device provided by the utility model comprises a base 1, a top plate 4 is arranged on the base 1, a first telescopic member 2 is fixedly installed on the base 1, the first telescopic member 2 drives the top plate 4 to move up and down, a plurality of telescopic rods 3 parallel to the first telescopic member 2 are fixedly installed on the base 1, the plurality of telescopic rods 3 are spaced and distributed, and the plurality of telescopic rods 3 are fixedly connected to the top plate 4, a second telescopic member 5 is fixedly installed on the top plate 4, a lifting frame 6 of a frame-type structure is fixedly installed on the output end of the second telescopic member 5, a cross bar 8 and a mud gun 12 are slidably installed on the lifting frame 6, and a sliding Two groups of brackets 7 are installed, and the two groups of brackets 7 are fixedly connected to the cross bar 8 and the mud cannon 12 respectively. The ends of the two groups of brackets 7 are fixedly installed with laser ranging sensors 20 for detecting the distance between the brackets 7 and the electric arc furnace. The cross bar 8 and the mud cannon 12 are distributed in a vertical plane and the cross bar 8 is located between the mud cannon 12 and the top plate 4. The mud cannon 12 is connected to a mud inlet bucket, a push plate 14 is slidably installed in the mud cannon 12, and a third telescopic member 13 for driving the push plate 14 to move is fixedly installed in the mud cannon 12. A top rod 9 is arranged at the end of the cross bar 8, and a power component 21 for pushing the cross bar 8 and the mud cannon 12 to move is arranged on the top plate 4.
[0024] In actual application of this embodiment, the base 1 is pushed to move to the use position, the height of the top plate 4 is fixed and adjusted, so that the cross bar 8 and the mud gun 12 are at a suitable height. When opening the eye, the cross bar 8 is pushed to move by the power component 21. When the cross bar 8 moves, the moving direction of the cross bar 8 is limited by the bracket 7 and the lifting frame 6. The cross bar 8 drives the top rod 9 to contact the submerged arc furnace. When the top rod 9 contacts the submerged arc furnace, the distance to the submerged arc furnace is detected by the laser ranging sensor 20 at the front end of the bracket 7. After that, the power component 21 drives the top rod 9 to move back and forth to open the eye of the submerged arc furnace. The change in the distance between the end of the bracket 7 and the submerged arc furnace is detected as the depth of the eye opening, which realizes the real-time detection of the depth of the eye opening of the submerged arc furnace, ensures the accuracy of the eye opening depth, improves the eye opening accuracy, and avoids the influence of eye opening errors on the subsequent use of the submerged arc furnace.
[0025] When the eye needs to be blocked, the cross bar 8 returns to its original position, and the connection between the power assembly 21 and the cross bar 8 is released. Then the second telescopic member 5 moves downward to make the mud gun 12 move to the position of the cross bar 8. Then the power assembly 21 is connected to the mud gun 12 and pushes the mud gun 12 to move along the moving trajectory of the cross bar 8, so there is no need to adjust the position of the base 1, and there is no need to adjust the position of the mud gun 12 multiple times to ensure that the mud gun 12 is aligned with the eye opening position, which is conducive to improving the accuracy of subsequent eye blocking. The power assembly 21 pushes the mud gun 12 to move, and when the front end of the mud gun 12 moves to the wall of the ore-blasting furnace, the laser measurement at the front end of the bracket 7 is used. The distance sensor 20 detects the distance to the electric arc furnace, and then the power component 21 continues to push the mud cannon 12 to move so that the end of the mud cannon 12 enters the appropriate depth in the eye opening. The laser ranging sensor 20 detects the change in the distance to the electric arc furnace, that is, the depth to which the end of the mud cannon 12 enters. Then, the third telescopic member 13 drives the push plate 14 to move, thereby pushing the eye-blocking mud in the mud cannon 12 into the eye opening for sealing. After the sealing is completed, the mud cannon 12 returns to its original position, realizing the detection of the eye opening sealing depth, thereby ensuring that the electric arc furnace is blocked at an appropriate depth, ensuring the blocking quality of the electric arc furnace, and improving the safety of the subsequent use of the electric arc furnace.
[0026] In an example of the present embodiment, the second telescopic member 5 and the third telescopic member 13 are respectively the second electric telescopic rod and the third electric telescopic rod, and of course they can also be other components such as hydraulic cylinders that can actively change their lengths. The second electric telescopic rod drives the cross bar 8 and the mud cannon 12 to move up and down, and the third electric telescopic rod pushes the plugging mud out of the mud cannon 12 through the push plate 14.
[0027] like Figure 1 , Figure 2 As shown, a high-precision electric arc furnace eye opening and blocking device is provided by the utility model. A mounting block 10 is fixedly installed at the end of the top rod 9. The mounting block 10 is slidably connected to the cross bar 8. A fixing screw 11 is provided at the end of the cross bar 8. The fixing screw 11 is threadedly connected to the mounting block 10.
[0028] In actual application of this embodiment, the top rod 9 is installed to the end of the cross bar 8 through the mounting block 10, and then the mounting block 10 is fixed by the fixing screw 11 to complete the fixed installation of the top rod 9. The top rod 9 can be easily replaced later, thereby improving the convenience of using the device.
[0029] like Figure 1 , Figure 2 As shown, a high-precision electric arc furnace eye opening and blocking device is provided by the utility model. The power assembly 21 includes a mounting frame 16, which is fixedly mounted on the top plate 4. A rotating power member 17 is fixedly mounted on the mounting frame 16. The rotating power member 17 drives a screw rod 18 to rotate. A movable plate 19 is rotatably mounted on the screw rod 18 to push the cross bar 8 and the mud gun 12 to move.
[0030] Specifically, the movable plate 19 is in sliding contact with the mounting frame 16 , and the movable plate 19 moves along the length direction of the cross bar 8 . The movable plate 19 cooperates with the electromagnet 15 fixedly mounted on the cross bar 8 and the end of the mud gun 12 .
[0031] When this embodiment is actually used, the rotating power part 17 drives the screw rod 18 to rotate, thereby moving the movable plate 19. When opening an eye, the movable plate 19 contacts the electromagnet 15 at the end of the cross bar 8, and at the same time, the electromagnet 15 is energized, so that the electromagnet 15 adsorbs the movable plate 19, and then the movable plate 19 is fixedly connected to the cross bar 8. At this time, the movable plate 19 can drive the cross bar 8 to move to open the eye. When blocking the eye, the movable plate 19 is fixedly connected to the mud gun 12 through the electromagnet 15 on the mud gun 12, and then it can drive the mud gun 12 to move to perform the eye blocking operation.
[0032] In an example of the present utility model, the rotating power member 17 is a motor, and of course it can also be other components capable of outputting rotating power, such as a hydraulic motor. The motor drives the screw rod 18 to rotate, thereby driving the cross bar 8 or the mud gun 12 to move.
[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
[0034] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
