Abstract

In a continuous refining process involving the addition of various materials to a bath of molten metal, the temperature of the additives is varied according to the thermal condition of the bath, the invention being particularly suitable for ensuring a constant rate of discharge of the product at the required temperature. In the embodiment particularly described, raw iron from a container (1) passes through a refining vessel (2) where it is first treated with oxygen from a lance (4). Powdered and reduced iron ore from a hopper (6) is fed into the bath through a further lance (7) either directly or after passing through a pre-heater (9), while remelted scrap is fed in from a container (10). The proportions of hot and cold ore, and of remelted scrap, added are controlled in accordance with the reading of a pyrometer located at the discharge end of the refining vessel. The partially refined metal then passes to a supplementary treatment vessel (12) where it is deoxidized with ferro-manganese added either cold from a hopper (14) or molten from a vessel (16) according to the indication of a further pyrometer (18).
