Use of Frequency Control to Optimize Induction Axle Scan Hardening
Authors:Valentin Nemkov, Robert Goldstein
Abstract:This presentation is a continuation of the optimal design analysis of scanning process and inductors for scan hardening of axles that had been reported in 2007 in two publications [1,2] and in presentation at a conference HES-07 in Padua, Italy . Improvements based on coil optimization at two frequencies (1 and 3 kHz) have been reported in these presentations. Current article describes what additional improvements may be achieved when two frequnces are used during the process of heat treating.
Vehicle axles are parts that have been induction heat treated for many years. Demands for increased vehicle reliability, fuel economy and performance have led to more challenging heat treatment specifications for axles. While being asked to produce better product, the automotive parts suppliers face an increased competition and relentless demands to lower costs.
