Abstract

888,634. Refining steel. ARBED, ACIERIES REUNIES DE BURBACH-EICHDUDELANGE S. A. Feb. 10, 1960 [March 3, 1959], No. 4654/60. Class 72. [Also in Group XII] A method of surface blowing molten metals comprises passing a main stream of gas through a nozzle and passing secondary streams of gas into the main stream so that the main jet diverges. As shown, the gas, e.g. oxygen, may be passed through a nozzle 5 which is arranged spaced from and centrally of a water-cooled double-walled tube 1. Another gas, or, if desired, the same gas, at the same, a higher or a lower pressure, may be passed through the space between the nozzle and the tube and into the main stream through nozzles 6 the axes of which may be directed downstream and towards the axis of the main jet or may be arranged angularly thereto to produce a spin. Variation in pressure in the secondary gas stream produces variation in the amount of divergence in the main jet. The main gas stream may contain finely divided fluxes in suspension. Specifications 844,987 and 845,393 are referred to.
