A method for increasing temperature homogeneity in a pit furnace wherein at least two ingots to be heated lean against a respective one of first and second opposite inner walls of the pit furnace to form an elongated space having a V-shaped cross-section between them includes arranging at least one lance for an oxidant with an oxygen content of at least 85 percent by weight and at least one lance for fuel in a furnace wall with their orifices opening into the furnace at a distance from each other for supplying the oxidant and fuel to said V-shaped space to be combustible therein, wherein the orifice of the oxidant lance is arranged above the orifice of the fuel lance and is directed for the oxidant to flow obliquely downwards and along a longitudinal direction of said V-shaped space.
