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