Abstract

A system and method of feeding pulverized or granular materials to a molten metal bath, characterized in that the system comprises a series of tanks for the materials to be fed, means for discharging an independently controllable quantity of material from each of the reservoirs to a common container, means through which a controlled amount of pressurized gas can be applied to the reservoirs and discharge devices, and a duct that starts from the container and is adapted for insertion under the surface of the molten metal of the bathroon.
