METHOD FOR REDUCING TARGET SURFACE FEATURES IN CONTINUOUS CASTING
First Claim
Patent Images
1. A method, comprising:
- providing a continuously cast article having a first target surface feature on a first surface of the continuously cast article; and
before cold rolling, removing material from the first surface of the continuously cast article by abrasion to provide a treated article, wherein a dimension of the first target surface feature on the first surface of the treated article is less than a corresponding dimension of the first target surface feature on the first surface of the continuously cast article.

Abstract
A method for reducing target surface features in continuously cast articles is described. The method can remove a target surface feature, such as a compositional variation or casting defect, from the continuously cast article by removing, before cold rolling, material from the continuously cast article surface.

9. A method, comprising:
-
continuously casting an alloy to form a strip having a target surface feature on a first surface of the continuously cast strip; and before cold rolling, reducing, by abrasion, a thickness of the target surface feature while maintaining a substantially constant width of the continuously cast strip derived therefrom to provide a treated strip, wherein the target surface feature is substantially removed from the first surface during the reducing step. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
