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.
Claims19
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 said tip portion located downstream of the feed portion and being of substantially the same width as the sum of the individual tubular sections.
An apparatus according to claim 14 wherein said plurality of hollow sections comprise a high melting point heat resistant material.
An apparatus according to claim 20 wherein said material is a ferrous alloy having high concentrations of chromium, cobalt and aluminum.
