A Novel Temperature Diagnostic System for Stelmor Air-Cooling of Wire Rods

摘要

A novel online and movable temperature diagnostic system was designed to capture the surface temperature profile of wire rods during the Stelmor air-cooling process. It consisted of an infrared pyrometer, a data logger, a cooling system, 3-axis steering gear, and a movable mechanical platform. A series of experiments had been conducted to investigate the relationship between the cooling rate and the mechanical properties of NLP(Non-Lead Patenting) wire rods. The temperature of the wire rods during the Stelmor air-cooling process was more accurately controlled through the use of this novel system and the variation in the tensile strength of NLP wires was reduced from 40 to 16.
