Abstract

Treatment agent is continuously added to a molten metal by pouring the latter into a passage and feeding a bar of agent into the flow. Introduction is such that a considerable disturbance is caused in the stream without interrupting the unity of global cohesion of the flow. The agent feed velocity is not greater than the consumption rate and the treated metal is discharged in to a casting zone. Preferably, the agent, which may be a grain refiner, is introduced as close as possible to the pouring gate of the reservoir. Particular application is to the treatment fo aluminium, zinc, copper, iron and nickel. The bar comprises the tretment agent and a principal alloy of the metal. Distribution of the agent is uniform. the process may also be used for introducing more of the metal itself, for cooling.
