The use of the Taguchi method for the elimination of pearlite colonies in wire rods for the fabrication of bars

$15.00

This study shows an application of the Taguchi method of orthogonal matrices in order to obtain a robust process, concerning grain size homogeneity, during hot rolling of medium carbon steel wire rods for the fabrication of bars. The main goal was to minimize the deviation of this microscopic characteristic in relation to its target value. This was done by the identification of the main variables that are related to the problem and then by the adjustment of their operating levels.
