Electric Arc Furnaces (EAFs) are widely used in the steel industry for the production of steel. EAF shells, also known as refractory linings, play a crucial role in the operation and efficiency of these furnaces. In this article, we will explore the benefits and advantages of EAF shells, highligh
READ MOREHow to reduce the consumption of three circumference electrodes in smelting is not only the technology of carbon manufacturers, but also the important work of smelting manufacturers to cooperate in the use and optimize the operation of electric furnaces.
READ MOREWith the goal of "high efficiency, low consumption, green and intelligent", steel enterprises need to select appropriate electric furnace type and production technology. The raw material of converter process is mainly liquid molten iron, the raw material of electric furnace process is mainly solid scrap, and the final product form is liquid steel. The different transformation of physical and chemical forms determines the different control methods.
READ MOREFocusing on the objectives of high production efficiency, simple function, environmental friendliness, intelligent control and diversified raw materials, electric furnace steelmaking technology has been continuously developed. The goal of high efficiency of electric furnace smelting is to shorten the smelting cycle and power on time as much as possible and reduce the smelting power consumption as much as possible.
READ MOREElectric furnace steelmaking mainly uses arc heat. In the arc action area, the temperature is as high as 4000 ℃. The smelting process is generally divided into melting period, oxidation period and reduction period. In the furnace, not only oxidation atmosphere but also reduction atmosphere can be caused. Therefore, the efficiency of dephosphorization and desulfurization is very high.
READ MOREElectric arc furnace melting uses the heat generated by the electric arc between graphite electrode and iron (molten iron) to melt iron and overheat molten iron. In the process of electric arc furnace smelting, when the iron is melted, the smelting operation of further increasing the temperature and adjusting the chemical composition is carried out under the condition that the molten iron is covered by the slag.
READ MOREElectric furnace equipment is usually a complete set, including electric furnace body, power equipment (electric furnace transformer, rectifier, frequency converter, etc.), switches, auxiliary auxiliary appliances (resistors, compensation capacitors, etc.), vacuum equipment, detection and control instruments (electrician Instrumentation, thermal instrumentation, etc.)
READ MOREIn the early days, the direction of rotation of the closing mechanism of the tap hole of DEMAC was vertical, and later it was mostly changed to the horizontal direction. For example, the BSE tapping technology in Germany, its advantage is that the plate that closes the tap hole moves horizontally, and the total height is low.
