What are the reasons for high electricity consumption in electric arc furnace steelmaking? As is well known, electric arc furnace steelmaking consumes a large amount of electricity. So, what are the reasons for the electricity consumption in electric arc furnace steelmaking? We can followunderstands it!
① Raw material conditions. The scrap steel used in electric furnace steelmaking, due to the requirement of using lightweight materials, pressed blocks, etc., often leads to high feed rates and thermal shutdown, resulting in significant heat loss. In the case of insufficient loading, a second feeding is required, and in some cases, there have been instances of three feeding, which has also increased heat loss. For each additional charge (with an average charge time of 5 minutes), the power consumption increases by about 7-12 kW · h/t. After raw material cleaning, it was found that after entering the oxidation period, the removal of C and P requires longer time and higher energy consumption.
② Skills of operators.
The electricity consumption during the melting period accounts for 60% -70% of the total electricity consumption, and the main waste of electricity is after cleaning.
. Blind slag flow during the dephosphorization process during oxidation is a common phenomenon, which wastes a lot of energy. ③ Affects objective conditions. During the smelting process, due to a shortage of electricity, there was a sudden occurrence of power outages and restrictions. Over time, the cooling and solidification of molten steel require melting again, resulting in a significant waste of electrical energy.④ Other accidents. If the operator operates improperly and the electrode breaks, a large amount of heat will be lost during the electrode processing. When the sample is restored during the recovery period, if the components are found to be unqualified, secondary oxidation must be carried out, which will also generate a large amount of thermal energy. Coal oxygen burner leaks during smelting process, interrupting melting; The wall mounted material of the furnace needs to open the furnace cover, which delays the smelting time to varying degrees and increases heat loss. Well, the above is the reason for the high electricity consumption in electric arc furnace steelmaking analyzed by the electric arc furnace manufacturer.
