Abstract
A nozzle which can be used repeatedly for the supply of liquid metal is made up of individual, hollow, refractory sections fitted together side by side in a metal frame. The hollow elements of the nozzle may feature, in addition to at least one longitudinal channel for the supply of liquid metal, channels to accommodate heating elements also running in the longitudinal direction.
Claims21
An apparatus for the continuous casting of molten metal comprising in combination a caterpillar track type mold and a nozzle for feeding said molten metal to said mold, the improvement comprising:
- a nozzle comprising a plurality of individually separable hollow elongated tubular sections, each of said sections having a peripheral wall defining at least one feed channel, said plurality of sections being mounted in side by side relationship such that a portion of said peripheral wall surface of one of said plurality of sections abuts a portion of said peripheral wall surface of another of said plurality of sections wherein the abutting portions of said peripheral wall surfaces of said plurality of hollow sections form a channel substantially parallel to said at least one feed channel.
An apparatus for the continuous casting of molten metal comprising in combination a caterpillar track type mold and a nozzle for feeding said molten metal to said mold, the improvement comprising:
- a nozzle having a feed portion and a tip portion, said feed portion comprising a plurality of individually separable hollow elongated tubular sections, each of said sections having a peripheral wall defining at least one feed channel, said plurality of sections being mounted in side by side relationship such that a portion of said peripheral wall surface of one of said plurality of sections abuts a portion of said peripheral wall surface of another of said plurality of sections wherein said abutting portions of said peripheral wall surfaces of said plurality of hollow sections form a channel substantially parallel to said at least one feed channel, said channel formed by said abutting portions of said peripheral wall surfaces being provided with means for heating the surface of said peripheral wall which is in contact with said molten metal.
