The consumption of graphite electrodes is mainly related to the quality of the electrodes themselves, as well as to steelmaking operations and processes.
(1) Electrode end consumption. Its consumption includes the sublimation of graphite material caused by high arc temperature, as well as the loss of chemical reactions between the electrode end and molten steel and slag. The electrode end consumption is also related to whether the electrode is inserted into the molten steel to increase.
(2) Oxidation loss on the outer surface of the electrode. In recent years, in order to improve the smelting rate of electric furnaces, oxygen blowing has been widely used, which has led to an increase in electrode oxidation losses. In general, the oxidation loss on the outer circular surface of the electrode accounts for about 50% of the total electrode consumption.
(3) Residual loss of electrodes or connectors. A small section of electrode or connector that is continuously used at the connection between the upper and lower electrodes is prone to falling and increasing consumption.
(4) The loss of electrode breakage, surface peeling, and chipping. These three types of electrode losses are collectively referred to as mechanical losses, among which the reason for electrode breakage and detachment is a disputed point between the steelmaking plant and the graphite electrode production plant in identifying quality accidents, as it may be due to issues with the quality and processing of graphite electrodes, or problems with steelmaking operations.
2023-12-11We all know that graphite has excellent chemical stability. After special processing, graphite also has the characteristics of corrosion resistance, good thermal conductivity, and low permeability. Therefore, it is widely used as heat exchangers, reaction tanks, condensers, combustion towers, absorption towers, coolers, heaters, filters, and pump equipment.
Generally speaking, the requirements for resistance to oxidation during the construction of graphite plates are becoming increasingly high. The service life of graphite plates continues to extend, and there has been a significant increase in the traditional material life. The anti-corrosion and insulation engineering has been proven to have a long lifespan through countless experiments. In this regard, it is always necessary to know the technical advantages and characteristics. After grasping the gap, it is still worth recognizing when applied in the industry. Enhanced processing and improved performance are also unique aspects of graphite plates in the market sales process. When promoting them, the advantages and characteristics of their materials can be basically seen. After grasping the basic technical requirements and cost-effectiveness, everyone feels that the performance and processing requirements will continue to improve, and the choices brought to customers will become increa2023-08-23The various properties of graphite plates are getting better and better
