Abstract
A blast pipe is formed of a plurality of concentric tubes, the cross-sections of which are designed for the fluid flows required for the refining of a metal bath, which are used initially as a burner. A second tube adjacent an outermost tube, projects beyond the end of the outermost tube, and is provided with a row of orifices in the projecting portion. The end of the second tube is closed by a metal cap soldered to the second tube with a hard solder which melts at a predetermined temperature in relation to the metal of the bath to be refined.
