FORFARANDE OCH ANORDNING FOR INITIERING AV EN GASHYVLINGSPROCESS

摘要

A method for starting a gas deseaming of ingots and billets employs a point-shaped heating source. A motion is imparted to said heating source parallel to the orifice of a gas-planing nozzle. An oxidizing gas jet emerging from said nozzle burns away metal melted by said point-shaped heating source. A device for performing this method comprises electric arc generating means including an electrode and guide means capable of guiding the electrode along a path opposite the orifice of a gas-planing nozzle and in parallel relation thereto.
