METHOD FOR INCREASING THE TEMPERATURE HOMOGENEITY IN A PIT FURNACE

摘要

A method for increasing temperature homogeneity in a pit furnace wherein at least one ingot to be heated leans against an inner wall of the pit furnace for providing a space having a triangular cross-section under the ingot between the ingot and the inner wall includes arranging at least one lance for an oxidant with an oxygen content of at least 85 percent by weight so that its orifice is arranged inside the furnace for supplying the oxidant to the space.
