Title:
金属融液の製造方法ならびにその方法において使用される多機能ランス
Document Type and Number:
Japanese Patent JP4563583
Kind Code:
B2
Abstract:
Charge materials containing metal and/or metal oxides are fed into the metallurgical vessel in solid and possible molten form. The energy for melting and final reduction of the charge materials are provided electrically or by combustion/ gasification of materials containing carbon. An Independent claim is given for a multifunction lance used for implementation of the method for producing a metal melt. The lance consists of several concentric tubes surrounding one another. The second tube is shaped as a Laval nozzle for delivery of oxygen, and surrounds a central tube serving for delivery of solid substances or dust. The fifth tube surrounding the fourth tube forms an annular gap whose discharge channels are directed away from the central longitudinal lance axis.
