摘要： The present invention relates to a refining lance. It relates more particularly to a lance of the kind used for supplying from above, onto a metal bath, the oxidizing gas required for refining the molten metal contained in a metallurgical vessel. It includes a rotating device to divide the refining gas flow into an even number of separate gas jets that are more or less identical. The gas jets exit the head of the lance in angles which are substantially equal with respect to the longitudinal axis of the lance but in diametrically opposite directions with respect to the said axis.

摘要： Nozzles for a refining lance are presented which are spaced upwardly from the head of the lance and supply post-combustion oxygen to the space above a molten metal bath undergoing refining. Each of the nozzles has a mouthpiece with two parallel sharp edges which are arranged in planes passing substantially through the axis of the lance and which are connected by slightly rounded edges. Above the mouthpiece of each nozzle is a converging part.
