Intermediate cold rolling

The use of an intermediate cold rolling step between hot dipping with Al-Si and diffusion annealing, to produce a near final thickness strip with increased Si content. The surface finish after dipping is also improved.

Advantages result in the:
- Magnetic properties
- Flatter strip
- Reduced coating thickness and increased uniformity therefore more consistent properties ad easier pickling.
- Removal of need for cold rolling to final thickness in the potentially brittle high Si state post diffusion annealing.
