Abstract
Metallurgical melting apparatus with a blow-nozzle or burner capable of swivelling in different directions. The blow-nozzle or burner comprises at least one tube. The nozzle-head (12) has a bulge, in the example described a spherical calotte (13), which is retained between two ring-seats (14 and 15) (the FIGURE).
Claims12
A metallurgical melting apparatus, in which sponge iron is melted to form liquid pig iron and reduction gas is produced from feed coal and oxygen-bearing gas, comprising a blow-nozzle mounted in the side-wall of said apparatus above the level of the melt capable of swivelling in different directions and having at least one tube, a nozzle-head (12) attached to said tube (6), having a spherical surfaced calotte (13) a forward ring-seat (14) anchored to the side-wall (1) of the melting apparatus sealingly contacting a forward surface of the calotte (13), and a rear ring-seat (15) contacting a rear surface of the calotte (13) which thrusts the callotte forward towards the forward ring-seat (14).
Blow-nozzle capable of swivelling in different directions and comprising at least one tube for installation in the side-wall of a metallurgical melting apparatus above the level of the melt, and a nozzle-head (12) attached to the tube having a spherical surfaced calotte (13) which is retained resiliently between two ring-seats (14,15) respectively contacting forward and rear surfaces of said calotte and formed as portions of two member (19,29) of a supporting structure, the ring-seat (14) contacting the forward surface of said calotte sealingly contacting same.
