The electric arc furnace automation control system mainly includes three aspects: the electric arc furnace body system, the Consteel horizontal feeding system, and the furnace door furnace wall oxygen lance system.
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 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 MOREEBT electric furnace can retain 10% ~ 15% steel and more than 95% slag through eccentric bottom tapping. EBT electric furnace realizes slag free tapping by leaving 10% ~ 15% steel, maintaining sufficient molten steel in the tapping box and rapid back tilting (3 °/s) of the furnace body during tapping and tilting.
READ MORERapid melting and heating are the most important functions of electric arc furnace, which begins after the first basket of scrap is added to the furnace. In order to melt the scrap steel and make the molten steel temperature reach the tapping temperature in the shortest possible time, the following operations are generally carried out in the EBT electric furnace: power supply at the maximum possible power, oxygen one burner nozzle melting, oxygen blowing and stirring, bottom blowing mixing, foam slag and other intensified smelting and heating technologies.
