1. A method of manufacturing a wire rod by continuous cast rolling, comprising the steps of:
(a) providing a molten metal made of copper to a tundish;
(b) feeding the molten metal from the tundish into a mold via a nozzle;
(c) continuously feeding an additive element directly to the molten metal in the mold without passing through the tundish and the nozzle to mix the additive element with the molten metal in the mold, wherein the additive element is one, two or more types of the additive elements of titanium (Ti), magnesium (Mg), zirconium (Zr), calcium (Ca), aluminum (Al), phosphorus (P), indium (In) and tin (Sn); and
(d) continuously casting the molten metal mixed with the additive element in the mold to form a cast material.
 
7. A method of manufacturing a wire rod by continuous cast rolling, comprising the steps of:
(a) providing a molten metal made of a master material to a tundish;
(b) feeding the molten metal from the tundish into a mold via a nozzle;
(c) continuously feeding an additive element directly to the molten metal in the mold without passing through the tundish and the nozzle to mix the additive element with the molten metal in the mold; and
(d) continuously casting the molten metal mixed with the additive element in the mold to form a cast material, wherein the additive element is made of a linear substance, and is continuously fed to the molten metal into a groove of a casting wheel of the mold from an additive-element feeding nozzle arranged between the mold and a tundish storing the molten metal not yet fed to the mold.
