CONTINUOUS ROLLED ROD COOLING AND CLEANING

摘要

A system for treating continuously cast and rolled copper rod using a non-acid liquid treating composition for effecting removal of oxide scale present on the surface of the rod as it emerges from the rolling mill and for cooling the rod prior to coiling. One or more treating zones are provided between the rolling mill and the coiling machine. The treating composition is preferably an aqueous solution including one or more of aliphatic monohydroxy alcohols, polyhydroxy alcohols, ketones; and alkyl and alkanol primary amines, secondary amines, and tertiary amines; or mixtures thereof. The treating solution is recirculated and monitored with the pH being maintained at a value in excess of 7.
