Abstract (en)

[origin: WO9841658A1] The invention relates to a method for feeding solids into metal or steel melts whereby granular solids required during the analysis adjustment are fed in a predetermined quantity into the turbulent regions of the metal melt in a dense flow process by means of a pneumatic conveying device in order to achieve a high output whilst avoiding expensive and complex measures associated with lances and capital-intensive investments for injection devices and lance-moving devices.
