Moreover, it may not be possible to operate the EAF and LF in an optimum manner if the bus voltage fluctuates drastically because it will lower the melting capability and thus increase the tap-to-tap time, causing an increase in production costs [].As a more catastrophic failure, power transient and ferroresonance can cause over-voltages that can degrade furnace transformer insulations.

electric arc furnace in operation - abbELECTRIC arc furnaces (EAFs) have played an increasingly important role in global steel production in recent years. EAF steel production was only about 405Mt in 2015, but increased by 28% to 517Mt in 2019, according to the World Steel Association (worldsteel).1 The longer-term future of the EAF also appears bright, thanks to the sustainability ...

modeling and energy efficiency analysis of the steelmaking ... - springerThis paper presents a comprehensive model of an industrial electric arc furnace (EAF) that is based upon several rigorous first-principles submodels of the heat exchange in the EAF and practical experience from an industrial melt shop. The model is suited for process simulation, optimization, and control applications. It assumes that the energy demand of the process is satisfied by six sources ...
cost and exergy analysis for optimization of charging materials for ...Expenditures on the charging materials used in an EAF + LF system at a steel plant in Turkey are optimized with allowance for different thermo-economic indices and different combinations of electric-arc furnace (EAF) and ladle furnace (LF). The EAF and LF are regarded as a single system, and the mass balance for the raw materials is determined based on literature data and company catalogues ...
