Abstract
Abstract A process and apparatus for producing continuous length shaped metal filaments by casting a stream of molten metal within a groove formed in the inner periphery of a cylindrical chill roll. The groove is flanked by a tapered opening of a material which has low thermal conductivity and which is not wetted when contacted by the molten metal. This novel technique increases the tolerance of the position in which the molten stream may be introduced into the groove while ensuring the production of an approximately rounded cross section by preventing the molten stream from spreading out of the groove.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
99 words
In a method of producing a shaped metal filament from a stream of molten metal deposited in a quenching groove formed in the inner periphery of a cylindrical chill roll wherein said quenching groove is provided immediately contiguous to the top thereof with a tapered opening of a material which has a substantially greater thermal insulating property than the chill roll, the improvement which comprises introducing the molten stream within the area defined by the width of the tapered opening afforded by said insulating material whereby said insulating material is not wetted and quenching said stream in said groove.
Claim 2
Dependent Claim
99 words
In a method of producing a shaped metal filament from a stream of molten metal deposited in a quenching groove formed in the inner periphery of a cylindrical chill roll wherein said quenching groove is provided immediately contiguous to the top thereof with a tapered opening of a material which has a substantially greater thermal insulating property than the chill roll, the improvement which comprises introducing the molten stream within the area defined by the width of the tapered opening afforded by said insulating material whereby said insulating material is not wetted and quenching said stream in said groove.
Claim 3
Dependent Claim
41 words
The method of claim 1 wherein the molten stream is ejected into the groove at an acute angle with the inner surface of the chill roll and in the plane of the groove in the direction of rotation of the roll.
