Abstract

a. Procédé pour injecter de la matière dans une masse fondue. b. Ce procédé consiste à maintenir un arc d'une manière en soi connue entre l'électrode 4 et la masse 6 fondue, tout en envoyant en même temps en continue de la poudre à l'aide d'un gaz 3 porteur sous une pression telle que la poudre pénètre vers le bas dans la masse fondue en dessous de la face libre de celle-ci et que la réaction souhaitée de la masse fondue soit obtenue. c. Industrie métallurgique.
