A copper alloy wire and a manufacturing method thereof are provided. The copper alloy wire includes: by weight percentage of components, 0.3 to 0.45 of argent, 0.01 to 0.02 of titanium, and a remaining part that is formed by copper and unavoidable impurities. The method for manufacturing the copper alloy wire is performing two-phase vacuum melting: first performing vacuum electric arc melting into a copper-titanium mother alloy, and then performing vacuum induction melting with remaining components into a copper alloy wire material by means of continuous casting; then drawing the copper alloy wire material into a copper alloy fine wire by a non-slip wire drawing device in a material even-flow wire drawing manner, and finally performing thermal treatment on the copper alloy fine wire by using argon as a protection gas, so as to complete a process of the copper alloy wire.

A strand guide device serves to deflect a freshly cast strand, typically made of metal, into the horizontal. During the deflection, the cast strand passes through a cooling chamber 1 inside the strand guide device 2, in which it is sprayed with a coolant 33, with the formation of steam 5. The steam forms at least a steam-air mixture 5 with sucked-in secondary air, which is sucked out of the cooling chamber by a suction device 20. In order to reduce the pollutant content of the sucked-in and sucked-off steam-air mixture 5 and its emission into the environment, pollutants, primarily dust, located in the steam-air mixture 5 are depleted by a separator 6, 6.

The invention further relates to a method for producing semi-finished products from a copper-nickel-zinc alloy.

Apparatus for producing elongate strands of metal comprises a rotatable wheel having a circumferential surface, at least one nozzle for directing a molten metal onto the circumferential surface and a collection means for collecting solidified strands of metal formed. The solidified strands are formed on the circumferential surface from the molten metal and are separated from the circumferential surface by centrifugal force generated by rotation of the wheel. The circumferential surface has a circumferentially extending structure having circumferentially extending edges and recesses formed between or bounded by the edges, and by an apparatus for controlling a gas pressure applied to the liquid metal which moves the liquid metal through the nozzle opening and delivers it to the circumferential surface of the rotatable wheel. The nozzle has a rectangular cross-section with a width of the nozzle opening in the circumferential direction of rotation of the wheel and a length transverse to the circumferential surface of the wheel which is greater than the width. A method and a wheel adapted for use in the apparatus are also claimed.
