Process and device for the continuous casting of very small-diameter wires directly from liquid metal

摘要

The subject of the invention is a process for the continuous casting of very small-diameter wires directly from liquid metal, according to which said liquid metal is made to flow out of a heated and pressurized container made of refractory material, forming a jet of liquid. metal having a diameter equal to or slightly greater than that of the wire to be cast, and said jet is made to solidify by making it penetrate into a layer of moving cooling liquid deposited on the internal wall of a drum rotating about a horizontal axis, wherein said container is fed, continuously or intermittently, with solid metal without interrupting casting and wherein said solid metal is melted inside said container. The subject of the invention is also a device for the continuous casting of very small-diameter wires directly from liquid metal, allowing this process to be implemented.
