Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
101 words
The method of making continuously cast elongate metallic products comprising the steps of fabricating by continuously casting an elongate metallic article in a grooved casting wheel wherein surface imperfections tend to be concentrated in a localized area adjacent a surface along the length of said article, passing said article through a first rolling step to elevate said localized area and form at least a portion of said area into a convex surface, scalping at least a portion of said convex surface formed in said first rolling step and subjecting said rolled and scalped product to at least one additional rolling step.
Claim 2
Independent Claim
101 words
The method of making continuously cast elongate metallic products comprising the steps of fabricating by continuously casting an elongate metallic article in a grooved casting wheel wherein surface imperfections tend to be concentrated in a localized area adjacent a surface along the length of said article, passing said article through a first rolling step to elevate said localized area and form at least a portion of said area into a convex surface, scalping at least a portion of said convex surface formed in said first rolling step and subjecting said rolled and scalped product to at least one additional rolling step.
Claim 3
Dependent Claim
16 words
The method of claim 1 wherein said scalping step is accomplished by a rotating cutting wheel.
Claim 4
Dependent Claim
15 words
The method of claim 1 wherein said product is fabricated from an alloy of aluminum.
Claim 5
Dependent Claim
15 words
The method of claim 1 wherein said product is fabricated from an alloy of copper.
Claim 6
Dependent Claim
15 words
The method of claim 1 wherein said product is fabricated from an alloy of magnesium.
