The present study established a numerical model to dynamically simulate the entire steel ingot melting process using the electric arc, which includes the continuous phase changing of solid steel, the surface deformation of steel ingot, and the close interaction between phases.
The percentage of electric steel produced with electric arc furnaces as the traditional melting unit around the world (without China, an exceptional case with 90 % oxygen steel) is around 45 %, and this percentage is growing.
When electricity runs between the anode and cathode and the cell reaches around 1,600 degrees Celsius, the iron oxide bonds in the ore are split, producing pure liquid metal at the bottom that can be tapped.
16 Σεπ 2022 · The model derived in this paper describes the melting process of solid scrap in an industrial Ultra-High-Power AC EAF producing stainless steels with a capacity of 150 Tons. The electrical power input is manipulated via the control system of the electrodes.
3 Απρ 2017 · The mechanical properties of those steels make sample preparation an additional challenge. The described experimental approach typically uses electrically conducting wire-shaped specimen with a melting point high enough for the implemented pyrometric temperature measurement.
23 Φεβ 2021 · Suggestions for optimized slag operation and resulting process improvements of DRI melting in the EAF are given. A dynamic mass and energy model of the DRI melting in the EAF is introduced to illustrate the implications of the adapted slag operation on the EAF process with DRI charges.
7 Αυγ 2024 · The article describes modern methods for controlling and optimizing the energy mode of melting in electric arc furnaces and units for out-of-furnace steel processing using optical emission spectroscopy systems. These systems enable the determination of melt and slag temperatures, plasma temperatures in the arc combustion area, and slag ...
