METHOD OF INGOTS CLEANING OF METALLIC PRODUCTS AGAINST SCALE Russian patent published in 2009 - IPC C23G5/00 B08B7/04 

FIELD: metallurgy.

SUBSTANCE: invention relates to metallurgy industry, particularly it relates to cleaning of casted metallic products against scale. Method includes installation of product into tanks with water in which it is formed gas blanket from gas mixture of hydrogen and oxygen with following impact on surface of product by depressed pressure pulse formed by electrical discharge in gas mixture by means of electrodes. In tank it is additionally located prominent casing inside of which in water it is located product and anode with cathode for formation of electrical discharge, after what from below into prominent casing from external generator of gas mixture it is fed mixture of gases of hydrogen and oxygen for formation of gas blanket, inside of which it is located metal fabric and to electrodes it is fed voltage for electrical discharge, beginning of hydrogen oxidation and formation of pulse of depressed pressure for impact for whole surface of metallic fabric.

EFFECT: invention provides increasing of productivity and reduction of technological cycle of meyallic fabrics cleaning of any configuration against scale.
