Continuous slab caster grade separators

[baglamas]

I know that angles, pipes or other objects can be used to separate consecutive grades of different chemistries at continuous slab casters.

I would like to know what other methods can be used to minimize mixing of different grades. It would also be useful to know what other objects are being used as separators and how effective they are.

Thank you in advance for your comments.

There are as many of these techniques as there are casters. Try doing a searce of US patents. The Patent office has a website( I forget the address ),and I know some techniques are described in patents.
The transition zone can be restricted by these gadgets.
