Precautions when using graphite electrodes

1.When loading materials into the furnace, in order to reduce the impact on the electrodes from material collapse, large chunks of material should be placed near the bottom of the furnace. Also, avoid the accumulation of non-conductive objects such as lime directly below the electrodes, as it may affect electrical conductivity or cause electrode breakage.   2.Pay attention to the position of the furnace cover. If the cover is misaligned, the electrodes may rub against the cover and get damaged or even break when moving up or down.   3.A set of connected electrodes should not be placed horizontally to prevent breakage.   4.When connecting electrodes, if any joint bolts are found to be loose, they should be tightened before use.   5.If gaps are found after connecting the electrodes, the cause must be identified and the gaps eliminated before use.   6.The electrodes should be used vertically to avoid tilting during operation.   7.Correct connection positions for electrodes and joints (refer to Figure 1).   8.Position requirements for electrode holders (refer to Figure 2), which should be placed outside the caution line of the top electrode.Note: The holder should not be placed inside the caution line or on the middle electrode, as this may cause electrode breakage.   9.Due to differences in materials and manufacturing processes among manufacturers, there are differences in the physical and chemical properties of electrodes and joints. Therefore, it is generally not recommended to interchange electrodes and joints from different manufacturers.   10.For furnaces with significant vibrations, using pins can help prevent loosening or disconnection.   1 2

Transportation and storage of graphite electrodes

1.When hoisting or inverting electrodes, operate with caution to prevent slipping and damaging the electrodes due to tilting.   2.To ensure the good condition of the electrode end face and thread, do not directly hang the electrodes at both ends with an iron hook for hoisting (see Figure 1).   3.Handle the joint box with care when loading and unloading to prevent knocking and causing thread damage.   4.Do not stack electrodes and joints directly on the ground, place them on wooden blocks or metal racks to prevent damage or contamination. Do not remove the packaging of temporarily unused electrodes and joints to prevent dust and debris from falling on the threads or electrode holes (see Figure 2).   5.Store the electrodes neatly in the warehouse, cushion the sides of the electrode stack to prevent sliding. The stacking height of electrodes should generally not exceed 2 meters.   6.Pay attention to rain and moisture when storing electrodes. Moist electrodes should be dried before use to prevent cracking and increased oxidation during steelmaking.   7.Do not store electrode joints near high temperatures to prevent the joint bolts from melting due to excessive heat.   1 2

DanTan Group won the 2020 global graphite electrode quality brand!

    At the 11th International Needle Coke and Application Market Summit Forum, which just ended in November 2020, Liaoning Dantan Technology Group was awarded the "2020 Global Graphite Electrode Quality Brand".The International Needle Coke and Graphite Electrode Application Summit Forum hosted by Xinmi Information was held in Xiamen, Fujian, China. Business representatives and industry experts attended. At the meeting, the new pattern of the global needle coke market in 2020 and the future market of the downstream market (graphite electrode, anode material) were discussed.   , presided over by sun qing:1, needle coke market into a new cycle, needle coke enterprises how to deal;2. The supply capacity of needle coke has been greatly improved, which brings challenges and opportunities to domestic graphite electrode enterprises;3. Whether the great development of needle coke industry can increase the export advantage of graphite electrode in China;4, scrap steel import liberalization, can reduce the cost pressure of electric furnace steel mills, to bring more opportunities to the electrode;5, needle coke price peak has passed, negative enterprises for raw material selection trend;6, power battery to needle coke negative material viscosity discussion;Six major issues of intense discussion, Liaoning Dan carbon technology group co., LTD., Han spruce to the scene to actively discuss.   Subsequently, the conference launched the "2020 Global Needle Coke Industry Quality Enterprise" and "2020 Graphite Electrode Industry Quality Enterprise" selection activities. In the end, Dan Carbon Group was named "2020 Global Graphite Electrode Quality Brand". I would like to thank the judges of the Conference for their support and encouragement. Thank our customers and leaders for their affirmation of Dan Carbon Group. Dan Carbon Group will continue its efforts to focus on the carbon industry and strive to become a professional, global graphite electrode manufacturer to provide users with high-quality products and services.
