Description

Use of high-conductivity oxygen-free (HCOF) rod represents an advantage when compared to ETP rod. Even though the process is simpler without the hot rolling step, minimizing the number of variables to be controlled, process “recipe” must be followed closely in order to guarantee an optimal quality product. On the other hand, getting the most out of HCOF rod requires some fine tuning in drawing, especially in the breakdown machine. This paper gives a brief glance at the main variables involved.
