Contoured mold for horizontal continuous casting

Claim 2

A horizontal continuous casting mold wherein a continuous cast strand is formed from molten metal therein comprising: a. an arcuate bottom having curvature in mutually perpendicular planes with the center of curvature in such planes being below said bottom: b. sidewalls connected to said bottom that are arcuate with the center of curvature being located outside of said mold; c. one end wall connecting said bottom and said sidewalls; and d. means to cool the said bottom and sidewalls.

Claim 3

The invention of claim 1 including: a. a metallic envelope enclosing said bottom, end and sidewalls.

Claim 4

The invention of claim 1 wherein: a. each sidewall intersects said bottom at an included angle that is equal to or is greater that 90*.

Claim 5

The invention of claim 1 including: a. means for reducing irregularities of the surface of the molten metal in said mold.

Claim 6

The invention of claim 4 wherein: a. said means includes one or more spaces apart members extending transversely across said mold and partially submerged in said molten metal.

Claim 7

The invention of claim 4 wherein a. said means includes; i. a material contacting the surface of molten metal in said mold, and ii. means to advance said material onto said molten metal surface as said cast strand emerges from said strand emerges from said mold.

Claim 8

In a continuous casting apparatus the improvement comprising; a. a tundish having a pouring nozzle extending downward into, b. a horizontally extending casting mold comprising, i. an arcuate bottom having curvature in mutually perpendicular planes with the center of curvature in such planes beIng below said bottom, and ii. sidewalls connected to said bottom that are arcuate with the center of curvature located outside of said mold, and iii. an end wall connecting said bottom and said sidewalls, and iv. means to cool said bottom, end and sidewalls, and v. a metallic envelope enclosing said bottom, end and sidewalls: c. means contacting the surface of molten metal in said mold for reducing irregularities on the surface of said molten metal; d. means for withdrawing a cast strand from said mold, and e. means for cooling the surface of said strand.

Claim 9

In a continuous casting apparatus the improvement comprising; a. a tundish having a pouring nozzle extending downward into, b. a horizontally extending casting mold comprising, i. an arcuate bottom having curvature in mutually perpendicular planes with the center of curvature in such planes beIng below said bottom, and ii. sidewalls connected to said bottom that are arcuate with the center of curvature located outside of said mold, and iii. an end wall connecting said bottom and said sidewalls, and iv. means to cool said bottom, end and sidewalls, and v. a metallic envelope enclosing said bottom, end and sidewalls: c. means contacting the surface of molten metal in said mold for reducing irregularities on the surface of said molten metal; d. means for withdrawing a cast strand from said mold, and e. means for cooling the surface of said strand.

Claim 10

The invention of claim 7 including: a. a plurality of rollers supporting said strand after it emerges from said mold.

Claim 11

In a continuous casting apparatus wherein molten metal partially solidifies to form a cast strand that is withdrawn from the casting apparatus, the combination comprising a. a horizontal casting mold having an arcuate bottom, arcuate sidewalls, and one end wall; and b. means contacting the top surface of molten metal in said mold for reducing irregularities in the surface of said molten metal as said strand is withdrawn from said mold.

Claim 12

In a continuous casting apparatus wherein molten metal partially solidifies to form a cast strand that is withdrawn from the casting apparatus, the combination comprising a. a horizontal casting mold having an arcuate bottom, arcuate sidewalls, and one end wall; and b. means contacting the top surface of molten metal in said mold for reducing irregularities in the surface of said molten metal as said strand is withdrawn from said mold.

Claim 13

The apparatus of claim 9 wherein: a. said arcuate bottom curves in mutually perpendicular planes with the center of curvature in such planes lying below and horizontal casting mold; with b. the center of curvature of said sidewalls is outside of said mold and wherein: c. each said sidewall intersects said bottom at an included angle that is equal to or greater than 90*.
