Abstract

A manufacturing efficiency of the wire rod made of the cast alloy including the additive element having the high activity to the oxygen is improved. An apparatus of manufacturing a wire rod includes: a tundish storing a molten metal; a mold for use in continuously casting the molten metal fed from the tundish; and an additive-element feeding unit continuously feeding an additive element (wire) to a feeding port of the mold.

First claim

What is claimed is:

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.

2. The method of manufacturing the wire rod according to claim 1 ,
wherein the additive element has a higher activity to oxygen than the copper.

3. The method of manufacturing the wire rod according to claim 1 ,
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.

4. The method of manufacturing the wire rod according to claim 1 ,
wherein, in the step (c), a first additive element is continuously fed to the molten metal in the mold, and
the molten metal fed to the mold in the step (b) includes the copper and a second additive element having lower activity to oxygen than the first additive element.

5. An apparatus of manufacturing a wire rod by continuous cast rolling, comprising:
a tundish storing a molten metal;
a casting wheel for use in continuously casting the molten metal fed from the tundish; and
an additive-element feeding unit continuously feeding an additive element directly into a feeding port of a groove of the casting wheel without passing through the tundish.

6. The apparatus of manufacturing the wire rod according to claim 5 ,
wherein the additive-element feeding unit includes an additive-element feeding nozzle made of a linear substance and continuously feeding the additive element to the feeding port of the casting wheel, and
the additive-element feeding nozzle is arranged between the casting wheel and the tundish.

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.
