Abstract

A rod or wire manufacturing system, a method for manufacturing a rod or wire, a method for heat treating of a rod' or wire, and a treated metal having an improved tensile strength are disclosed. The cooling unit includes at least one adaptable quenching zone and at least one adaptable soaking zone (isothermal), so as to conduct a patenting treatment. The heat transfer coefficient during quenching and soaking is adjusted by the content of air bubbles in the foamed liquid quenchant, and by the flow velocity thereof. The system can treat a plurality of wires simultaneously.
