During the smelting process, it is necessary to deliver strong currents of tens or even hundreds of kiloamperes into the furnace. Such large currents are transmitted through short networks. Short network, also known as high current line, refers to the general term for the carrier fluid from the secondary output terminal of a transformer to the electrode (including the electrode). The strong current flowing through the short network conductor will inevitably form a strong magnetic field around the short network conductor (copper busbar), and generate significant power losses in the short network conductor and the steel components around the conductor, Causing fever. Electric furnace is an important process equipment in the steelmaking industry. During smelting, it is necessary to deliver a strong current of hundreds of thousands or even hundreds of thousands of amperes into the furnace. Such a large current is transmitted through a short network. Short network (busbar system), also known as high current line, refers to the general term for the carrier fluid between the secondary output terminal of a transformer and the electrode (including the electrode).Detailed Photos Short network composition1) Compensator - Connect the low voltage end of the furnace transformer to the fixed part of the short network.2) Busbar - the longest fixed part of the short net, which may be a rectangular copper bar or a water-cooled copper tube.3) Fixed connection socket - used to connect water-cooled flexible cables from busbar to short network and transmit current.4) Water cooled flexible cable - used to transmit current from a fixed connector to a same electrode holder Short network characteristics 1.large current The strong current flowing through the short network conductor (copper busbar tube) will inevitably form a strong magnetic field around the short network conductor and cause significant power loss in the short network conductor and surrounding steel components. Conductors cause heat generation.2.Short length The entire short network (copper busbar) length of a large furnace shall not exceed 20m. Due to the high loss of short networks, their length should be shortened as much as possible during design, especially the length of water-cooled flexible cables, to minimize the loss of short networks.3.Complex structure The different conductors in the short network (water-cooled busbar tube) have different structures, shapes, parallel conductor quantities, and arrangement methods. Therefore, the design of the busbar system should consider the effects of skin effect and proximity effect, and select the conductor cross-section according to the specified current density. At the same time, attention should be paid to the reasonable configuration and optimal transposition of conductors to minimize effective inductance, balance the current of each conductor, and make the phase parameters as close as possible.4.Poor working environment The water-cooled high current bus conductor operates in harsh environments with high temperatures and high levels of conductive dust.Related products Customized metallurgical machinery equipment series: electric arc furnace, submerged arc furnace, LF refining furnace, vacuum furnace, induction furnace, dust removal system, water treatment equipment, etc. Providing the most advanced equipment integration services, metallurgical equipment can be customized according to different customer needs, and production capacity can be adjusted according to customer requirements. The projects we have completed Sanrui provides integrated services for metallurgical furnace equipment. The Sanrui ore smelting furnace and electric arc furnace metallurgical furnace are manufactured using cutting-edge technology to ensure efficient and high-quality melting and smelting processes. These melting furnaces are capable of smelting and melting various materials, including steel, iron and alloys, ferroalloys (such as tungsten iron, high carbon manganese iron, high carbon silicon iron, high carbon chromium iron, nickel iron alloy), industrial silicon, calcium carbide, corundum, yellow phosphorus, etc., with precise temperature control and minimal energy consumption. By using SanRui metallurgical furnace equipment, metallurgical enterprises can improve productivity and reduce production costs, ultimately increasing profitability.Services provided by SanRuiTechnical advantages 1.Practice has proven that the electrical parameters of the short network play a decisive role in the normal operation of the furnace.The productivity of the furnace, the service life of the furnace lining, power loss, and power factor largely depend on the selection of short network electrical parameters. 2.A reasonable water-cooled high current busbar design must ensure stable combustion of the arc in the furnace, minimal electrical loss, high power factor, and three-phase power balance. The resistance and reactance of copper busbars must be reasonable minimum values. The three-phase impedance should be balanced. The use of materials with short mesh structures should be minimized as much as possible, especially the consumption of non-ferrous metals, which should be easy to maintain and operate reliably. After optimizing the electric arc furnace technology, Sanrui has achieved the optimal balance between raw materials, scrap preheating, energy conservation and environmental protection, smelting process control, automation control, smelting cycle, and production capacity. The electric arc furnace inputs electrical energy to the electric arc steelmaking furnace through graphite electrodes, using the arc between the electrode end and the furnace charge as the heat source for steelmaking. Electric arc furnaces use electrical energy as a heat source and can adjust the atmosphere inside the furnace, which is extremely advantageous for melting steel grades containing more easily oxidizable elements. By utilizing high-temperature flue gas from electric furnaces and preheating raw materials through technology and equipment, high efficiency, energy conservation, environmental protection, and high yield can be achieved. With the improvement of electric arc furnace equipment and smelting technology, as well as the development of the power industry, the cost of electric furnace steel continues to decrease. Nowadays, electric furnaces are not only used for producing alloy steel, but also for producing ordinary carbon steel and iron concentrate pellets.1.
