Reasons for Power Consumption in Electric Arc Furnace Steelmaking
1. Raw Material.
As we all know, the steel used for electric arc furnace steelmaking is scrap steel, because the raw materials required for electric arc furnace steelmaking are light and thin materials, pressing blocks, etc., which will result in high temperature and shutdown when feeding, so the heat loss will be very large. If one charge is insufficient, it will need to be fed again, or even three times, which will cause a lot of heat loss. A large amount of power consumption is required for each charging. It is also worth noting that C and P are higher after the raw material is cleaned up. When entering the oxidation period, C and P removal also takes a long time, which will greatly increase energy consumption.
The technology referred to here is electric arc furnace steelmaking, which refers to the operator's skill. If the operator's skill is not good, it will waste a lot of lime and energy, which in turn will greatly increase power consumption.
How do you understand that objective conditions can also lead to increased power consumption? For example, in the process of electric arc furnace steelmaking, we suddenly trip due to lack of electric energy. Over a long period of time, molten steel cooling and solidification need to be melted again. This process also wastes a lot of electric energy.
