NOZZLE ASSEMBLY

摘要

A nozzle assembly for casting continuous metal strips includes a nozzle for extruding molten metal. The nozzle has a nozzle body (12), a nozzle inlet opening (14), a nozzle exit orifice (16) and a nozzle mounting surface (24) located proximate to the nozzle inlet (14). A reservoir (1) contains the molten metal and is in fluid communication with the nozzle. The reservoir (1) has a reservoir outlet (10) opening for flowing molten metal therethrough and has a reservoir mounting surface (22) located proximate to the reservoir outlet (10). The reservoir mounting surface (22) is adapted to mate with the nozzle mounting surface (24) and allow a relative, sliding-type movement therebetween due to a differing thermal expansion of the nozzle relative to the reservoir (1). A heat resistant seal (21) between the nozzle mounting surface (24) and the reservoir mounting surface (22) minimizes molten metal leakage therebetween, and a force mechanism (30) resiliently urges the nozzle mounting surface (24) toward the reservoir mounting surface (22) to mate the nozzle and reservoir (1) together.
