Direct reduction process and simultaneous continuous casting of metallic materials in a crucible to form rods

Abstract

Abstract A continuous casting technique of ferro-alloys is provided wherein a water-cooled copper crucible having a relatively enlarged upper portion and a reduced lower portion defining a relatively small reaction zone. One or more electrodes are introduced either of a consumable or non-consumable variety. In either of these approaches, metal oxide, reducing agent, flux and addition materials are dispensed in the crucible and the desired reaction is initiated between the lower end of the electrode and a conveniently located negative pole. Relatively high temperatures are attained and upon melting of the slag, the alloying reaction takes place in continuous fashion. This reaction is enhanced by induction stirring which ensures the uniform dispersion of the several ingredients introduced into the reaction zone. As the molten alloy is formed, it is separated and gradually lowered at a controlled rate. Provisions are made for cooling the alloy as it is produced and lowered from the crucible. The discharged alloy is in rod shape and is thereafter cut into predetermined lengths or placed in any other form for the selected application.
