Quality monitoring for coarse-grained anisotropic cold-rolled transformer steel in the presence of textural inhomogeneity

A regularity has been observed in the quality monitoring of rolled electrot echnical steel involving the use of magnetic texture meters; many local are as in the steel have a distribution for the easy magnetization axes of the individual grains that do not fit a normal distribution. These are parts of the steel having a structural inhomogeneity probably due to technological deviations during the hot rolling or subsequent heat treatment, and they ar e detected from the increased widths of the recordings provided by the text ure meters. They can be used by the operators of the rolling mills as signa ls for eliminating these unsatisfactory parts of the metal from the total l ength of the roll and thus assembling batches of steel uniform in quality.
