Description

Technical Field

[0001] The invention relates to the technical field of electrodes, in particular to an auxiliary device for flat ground connection electrodes. Background Art

[0002] In electric furnace production, electrodes generally consist of three electrodes in one phase, and the three electrodes are arranged in order of top, middle and bottom. In the prior art, after an electrode is broken, a large part of the upper end of the middle electrode is damaged. Some manufacturers will use the middle electrode to pick out wire for secondary use, but the lower electrode cannot be used. Generally, the lower electrode is oxidized due to high temperature and high oxidation resistance. The large-diameter electrode storage barrel is a curved wheel, which may not be able to clamp the electrode, resulting in waste and the electrode is treated as scrap. At the same time, some broken electrodes have the intact wire end at the thin end. Because the electrode storage barrel has a curved wheel, it may not be able to clamp the electrode, and there is a risk of falling off. Therefore, in these two situations, the electrodes are usually scrapped. The current price difference between scrap electrodes and usable electrodes is large, which can easily cause a large amount of economic losses to the company. Summary of the invention

[0003] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide an auxiliary device for connecting electrodes on the ground, so as to directly connect two electrodes that are to be scrapped, avoid the scrapping of the electrodes, and recover losses for the enterprise.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an auxiliary device for connecting electrodes to the ground, comprising a middle branch and two bottom plates, the top of the middle branch is fixedly connected to an upper branch, the bottom of the middle branch is fixedly connected to a lower branch, rollers are provided at the tops of the two bottom plates near the left and right sides, and fixed plates are inserted at the front and rear sides of the rollers.

[0005] Preferably, the bottoms of the four fixing plates on the same side are fixedly connected to the top of the same bottom plate.

[0006] Preferably, electrodes are provided on the tops of the four rollers.

[0007] Compared with the prior art, the present invention has the following beneficial effects:

[0008] The present invention directly connects two electrodes that are to be scrapped, thereby avoiding the scrapping of the electrodes and recovering losses for the enterprise. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] See also Figure 1-5 The present invention provides a technical solution: an auxiliary device for connecting electrodes to the ground, comprising a middle branch 2 and two bottom plates 7, wherein the top of the middle branch 2 is fixedly connected to an upper branch 1, and the bottom of the middle branch 2 is fixedly connected to a lower branch 3, rollers 5 are arranged on the tops of the two bottom plates 7 near the left and right sides, and fixed plates 6 are inserted on the front and rear sides of the rollers 5, and the bottoms of four fixed plates 6 on the same side are fixedly connected to the top of the same bottom plate 7, and electrodes 4 are fitted together on the tops of the four rollers 5.

[0018] Working principle: find the relevant electrode 4, and then place the electrode 4 on the top of the four rollers 5. The center level of the roller 5 can be adjusted according to the size of the electrode 4. When placing the bottom plate 7, it is necessary to pay attention to aligning it, and place the electrode 4 with wires at both ends on the top of the roller 5. Manually rotate the electrode 4 to test the working condition, lubrication and rotation of the test equipment. One person can operate it. The power source here can be either electric or manpower. After finding the center of gravity of the lower support 3, use a crane to lift it, while turning the electrode 4 with wires at both ends, while docking with the crane, or you can use a forklift to operate. The key is to let the electrode 4 rotate on the equipment, so as to dock with the lower support 3. Then there is a 1mm gap between the electrode 4 and the lower support, and the electrode is stored in the equipment. A top tightening wire is added to the barrel to tighten the last seam. The gap of about 1mm is rotated into place because during smelting, the high-temperature and highly oxidizing atmosphere of the flue gas in the furnace causes oxygen and heat to enter the joint from the seam, which will cause the electrode 4 to fall off. The electrode 4 originally vibrates up and down. If it is not tightened, the end face will not be able to generate supporting force, increasing the risk of breakage. If it is not rotated tightly, there may also be a risk of falling off during the lifting process, which is easy to cause blow injuries. Once the electrode 4 accidentally falls into the molten steel, it will take a long time to completely melt, which is easy to cause a high carbon situation, which will affect the alloying of the refining furnace later. It may also need to be turned over, and the corresponding oxygen consumption will increase, which will also disrupt the production rhythm of continuous casting.

[0019] For example, calculate the carbon addition effect of a 650 electrode in molten steel;

[0020] The electrode oxidized by 2.7m is calculated as 1400kg, the yield is calculated as 100% gross, the content is calculated as 100%, and the molten steel is calculated as 145 tons. The maximum carbon increase is as follows:

[0021] 1400*100%*100% (maximum yield) ÷ 145 ÷ 1000 = 0.965% (equivalent to 96.5 monthly carbon allocations).
