Abstract

800,833. Nozzles. BRITISH OXYGEN CO., Ltd. May 22, 1957 [May 29, 1956], No. 16627/56. Class 51 (1). In a water-cooled nozzle for supplying oxygen or other gas for refining molten metal having an inlet gas passage 11 and an outlet throat 12 of substantially less cross-section than the passage 11, the cooling water passages 16, 17 formed in the thickness of the nozzle wall do not extend towards the nozzle tip beyond the beginning of the throat 12. In a modification. Fig. 2, not shown, the nozzle may be of the convergent divergent type.
