A method for operating a hearth furnace encompassing a furnace chamber heated by at least one burner, including: a) introducing metal-containing material into the hearth furnace, b) melting the metal-containing material in a first melting phase until a melting bath surface has formed, c) melting the metal-containing material in a second melting phase after the melting bath surface has formed, d) removing and/or holding the melted metal, characterized in that the at least one burner is operated during the phase (b) such that a larger portion of burner capacity is emitted in convection rather than in radiant energy, and that respective portions of convection heat and of radiant heat emitted by the at least one burner are adjusted specifically via adjustment of brightness and/or size, in particular length of a flame of the at least one burner. |
