An improvement in the manufacture of cube-on-edge oriented silicon steel; the improvement comprises coating the surface of the silicon steel with a manganese-bearing material prior to texture annealing, whereby secondary grain growth is inhibited during texture annealing to achieve reduced watt loss. Cube-on-edge oriented silicon steel in the form of sheets is known for use in various electrical applications including transformer cores. With cube on-edge silicon steel the alloy is characterized by secondary recrystallization in the (110)001 position, which is termed the cube-on-edge position. This material in sheet form has the direction of easy magnetization in the direction of rolling. In …

Why it's free to use
- Granted October 1, 1985. A Canadian patent filed before October 1, 1989 lasted 17 years from grant, so its term ended October 1, 2002.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
