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.
L'invention concerne un procédé permettant d'apporter des matières solides dans des masses fondues de métal ou d'acier. Les matières solides granuleuses requises dans le cadre de l'ajustement des analyses sont apportées en quantité déterminée au moyen d'un dispositif de transport pneumatique et selon le principe du flux dense dans les zones turbulentes de la masse métallique fondue. Ce procédé offre un rendement élevé tout en évitant les mesures coûteuses et complexes et les lourds investissements liés aux installations d'insufflation et équipements à lances.
