copper rod upward continuous casting machine

the upward machine is used for making of oxygen-free copper rod with high-quality by adopting upward continuous casting process.

1.  Useage

This production line adopts the upward casting continuous technology, it is a specialized equipment to produce cast condition oxygen free copper rod with high-quality and large –length. Oxygen free copper rod is a high conductivity material with high electrical conductivity, low oxygen content, excellent mechanical properties and other characteristics, and be widely used as conductive materials in Copper rod, Copper Wire and magnet wire industries.
