A METHOD FOR MELTING STEEL

摘要

The present invention relates to a method for melting steel in an electric arc furnace (EAF). A hot heal (15) is provided in the EAF. Metal scrap (16) is loaded into the EAF. The metal scrap(16)is melted in the EAF. According to the invention the mass of the hot heel (15) in relation to the mass of the metal scrap that is initially beyond the surface of the hot heel is a certain minimum. This minimum is 0,75 times the relation between the heat required to melt the metal scrap beyond the surface of the hot heel (15) and the het that can be taken from the hot heel without it being solidified when a theoretical heat balance calculation is applied as defined in a formula.
