Title: Method for measuring grain size of primary recrystallization in electromagnetic steel plate
Inventor: MOGI TAKASHI
IPC: G01N27/72
Filed: 1995-12-22
Abstract: PROBLEM TO BE SOLVED: To measure the average grain size of primary recrystallization in electromagnetic steel plate by removing the cause of fluctuation in iron loss, i.e. the effect of inclusion in steel plate. SOLUTION: Iron loss is measured with flux density at two points or more and the iron loss-primary crystallization grain size error caused by impurities in a steel plate is predicted using a flux density B-iron loss W (B-W) curve obtained from the iron loss at two points. Iron loss is corrected by removing this error and the grain size of primary recrystallization is measured. Since the predicted B-W curve is varied as when the inclusion, e.g. nonmagnetic material, is abundant, iron loss of steel plate containing no inclusion is predicted from the variation and then the average grain size of primary recrystallization is calculated thus enhancing the accuracy in the measurement of grain size effectively.
