APPARATUS FOR VIBRATION PULSED TREATMENT OF MELTED METAL Russian patent published in 1995 - IPC

FIELD: metallurgy. SUBSTANCE: apparatus has additional nozzle 23, mounted on boundary of metal-slag separation. In the case both tips are made with outer diameter, that is equal to 0.2 - 0.5 of inner diameter of capacity and has conical holes, smaller bases of which are oriented alternately up and down and total area of smaller bases of holes is equal to 0.1 - 0.15 butt surface area of tip. Striking and acoustic waves, that are formed in discharge chamber, are passing through waveguide 21 and nozzles 22 and 23 and enter melted metal. Turbulent streams are formed in conical holes, facilitating intensive mixing of molten bath and increasing its uniformity. EFFECT: increase of efficiency of treatment. 3 dwg
