Definitions
- ABSTRACT A nozzle for the delivery of the molten metal to a Foreign pp n l' ty Data mold with continuously moving walls in a strip casting June 24, 1970 Switzerland 9611/70 process for metals, especially non-ferrous metals such as aluminum and aluminum alloys, the nozzle includ- [52] US. Cl. 164/279 ing a mouthpiece having inserts provided on its outer [51] Int.
- the delivery nozzle for the metal is the most critical part. This is due mainly to the fact that there are very few materials available which are capable of withstanding the high temperatures of the metal flowing through them and, in cases where the casting material is aluminum or an alloy of aluminum, then the delivery nozzle must be capable of withstanding the erosion or the dissolution in the metal itslef.
- graphite is one. Graphite, however, has the disadvantage of possessing a very high heat conductivity and by it the heat becomes conducted so quickly away from the molten metal that the metal wil have the tendency to solidify in the nozzle itself.
- an object of the present invention to provide a nozzle for the delivery of the molten metal to a mold with continuously moving wallsin a strip casting process for non-ferrous metals, expecially for aluminum and aluminum alloys, wherein the nozzle is capable of withstanding the high temperatures and erosion affects of the metal and, at the same time, is capable of producing a high quality stripcasted material havin a relatively wide width and a relatively thin thickness.
- a flat nozzle for the delivery of the molten metal, at least the portion of said nozzle which comes into contact with the molten metal, being made of a heat resistant material having a negligible heat conductivity and a high chemical resistance to the molten metal flowing therethrough, said nozzle comprising spacer means including a series of inserts provided on outer edge portion of the nozzle over the entire extent thereof and protruding above a general surface of said nozzle to an extent preventing a direct contact of the nozzle surface with portions of the halves forming said mold and entry of the molten metal between the nozzle and the mold, said inserts comprising a self-lubricating material.
