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.

An improved process for the continuous casting of very small-diameter wires directly from liquid metal, according to which said liquid metal is melted inside of and made to flow out of a heated and pressurized container made of a 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 improvement comprises the step of feeding said container with solid metal from a closed and pressurized vessel during casting to obviate the need for interrupting casting to periodically charge said container with metal.
An improved device for the continuous casting of very small-diameter wires directly from liquid metal of the type comprising a drum fitted with means for setting it in rotation about a horizontal axis, a layer of a cooling liquid deposited on the inside surface of said drum, a container made of refractory material, containing said liquid metal, and fitted with an outlet orifice overhanging said layer of cooling liquid, means for melting and heating said liquid metal and means for injecting a pressurized inert gas into said container, wherein the improvement comprises a pressurized vessel containing said metal in a solid state, in divided form, and means for feeding said container, continuously or intermittently, with said solid metal from said vessel under pressure during casting to obviate the need for interrupting casting to periodically charge said container with metal.
