ABSTRACT:
A lance head for a refining lance, comprising, a lance head bottom member, a plurality of expanding nozzles connected to the bottom member, a supply line associated with the bottom member for supplying coolant thereto, a return line associated with the supply line for channeling coolant away from the bottom member and a flow guide member connected between the supply line and the return line. The flow guide member extends across the plurality of expanding nozzles and includes a surface facing the bottom member defining a coolant passage therewith. The flow guide member surface is concave in the area of the nozzles so that the cross-sectional area of the flow passage is constant as coolant flows past the nozzles. The edge of the flow guide member surface extends beyond the nozzles and at an oblique angle to a central portion of the bottom member between the nozzles. The flow guide member includes a top surface and a distributor member is mounted in the lance head at a location spaced from the top surface of the flow guide member. The top surface of the flow guide member and the distributor member define a second coolant passage through which coolant passes into the return line from the aforementioned coolant passage. The top surface of the flow guide member is convex and the surface of the distributor member is concave to define a smooth curved second coolant passage which returns coolant to the return line without turbulence and under low resistance.
