Abstract

In this paper, exergy analysis was applied to the ladle furnace refining process of modern clean steelmaking. Results showed that, exergy loss induced by unavailable electric energy is the largest, and the electric energy efficiency is 46.20%. To cut down the unavailable electric energy, industrial experiments of submerged arc heating were carried out combined with slag composition modification. Results showed that, submerged arc heating can be achieved within most heating period, average heating rate increased by 0.5℃•min-1, unavailable electric energy decreased by 21.730 MJ per ton steel, and electric energy efficiency enhanced by 14.84%.
