ABSTRACT:
For introducing additives, such as inoculating agents, into a metal bath, the additive is held in a supply container. A slide device carries measured amounts of the additive from the supply container to an immersion pipe extending downwardly into a metal bath located in a vessel. A flow of gas is provided into the immersion pipe adjacent the point where the additive is introduced into the pipe. The gas carries the additive downwardly through the immersion pipe for mixture into the metal bath. The additive can be supplied continuously or in intermittent portions to the immersion pipe. The additive is introduced below the surface of the metal bath in accurately measured amounts in a safe reproducible manner.
