-edge) Grain-oriented silicon steels are known for use in a variety of hemodynamic equipment, including transformer cores. Cube-on-Edge For silicon steels, this alloy has a secondary recrystallization feature at the (110)[0011 position, referred to as the cube-on-edge position. This phase material in sheet form has a direction of easy magnetization in the direction of rolling. Applications of this material, particularly when used in the manufacture of transformer cores, require that the material have low watt losses, since electrical energy consumption is reduced as iron losses are reduced.

It has been found that the watt loss of the steel can be reduced by serrating in a direction essentially perpendicular to the 011 crystal direction. The depth of this serration is typically 0.02
5 mm (0,001 inch), but the range is 0.05 to 0.0057111 (0,002 to 0.00

The method of the present invention is applicable to cube-on-edge silicon steels in general, but is particularly suitable for compositions with weight t<: Five 10,2 mil thick 12-strip Epstein packs of the composition were prepared for testing. Two sets of the final normalized packs were used as comparative samples (Comparative Sample 1 and Comparative Sample 2), and the remaining six sets were serrated according to the method of the present invention in the rolling direction and [001] grain direction of the steel.

る。A single strip test was performed on eight strips from each pack described above to determine whether tension further reduced the watt loss of the serrated strips. In the test, the watt loss was first measured without applying tension, then the stress coating was applied to eight strips from each pack, and the watt loss was measured after applying tension using a tension generating core plate. The average watt loss for the eight strips is as follows: As can be seen from this data, serrating, when combined with the stress of the present invention, is even more improved than serrating alone in reducing watt loss.
