Microstructure and magnetic properties of heatproof domain-refined grain-oriented silicon steel sheets were studied. Local strains were introduced using two types of gear roll as well as cog tips, one 35 [mu]m and the other 85 [mu]m. After the local strains were introduced onto sheets, the distribution of hardness near the groove was measured. The nuclei of micrograins were investigated at various applied rolling loads. After stress-relief annealing, various shapes of micrograins and grooves were observed. The effect of these various shapes of grooves and micrograins on magnetic properties was clarified. The role of micrograins and grooves on domain refining is discussed.
