1.8 mm copper rod

method for producing 1.8 mm copper rod:

1. Continuous Casting:

   • Electrolytic copper cathodes are melted in specialized furnaces.
   • The molten copper is continuously poured into cooled molds to form thick rods (billets).

  Hot Rolling:

• • The cast billets are passed through several rolling stages to reduce their diameter to around 8 mm.

    Cold Drawing:

• • The 8 mm rod is further drawn through wire-drawing machines with successive dies to achieve the desired diameter of 1.8 mm.
  • This process ensures high precision and uniformity in diameter.

Extrusion

In some cases, extrusion is also used for producing copper wires:

1. Copper is melted and poured into extrusion molds.
2. High pressure pushes the material through a die to achieve a specific diameter.
3. The extruded wire is cooled and further drawn to 1.8 mm if necessary.

Annealing Process

After drawing the wire to 1.8 mm, it may undergo annealed copper:

• This heat treatment increases the wire’s flexibility.
• It also enhances its mechanical and electrical properties.

Benefits of Continuous Casting and Rolling:

• High-quality output.
• Faster production rates.
• Lower manufacturing costs.
