Abstract
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.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
191 words
An apparatus for casting continuous metal strip comprising: (a) nozzle means for extruding molten metal, which has a nozzle body, a nozzle inlet opening, a nozzle exit orifice and a substantially planar nozzle mounting surface located on a nozzle flange proximate to said nozzle inlet; (b) reservoir means in fluid communication with said nozzle means for containing said molten metal, said reservoir means having a reservoir outlet opening for flowing said molten metal therethrough and having a substantially planar reservoir mounting surface located proximate to said reservoir outlet which is adpated to mate with said nozzle mounting surface and allow a relative, sliding-type movement therebetween due to a differing thermal expansion of said nozzle means relative to said reservoir means; (c) resilient, heat resistant sealing means located between said nozzle mounting surface and said reservoir mounting surface for minimizing molten metal leakage therebetween; (d) heater means disposed about said nozzle for heating molten metal contained therein; and (e) force means for moving said heater means into contact with said nozzle flange and resiliently urging said nozzle mounting surface toward said reservoir mounting surface to mate said nozzle and reservoir means together.
Claim 2
Independent Claim
191 words
An apparatus for casting continuous metal strip comprising: (a) nozzle means for extruding molten metal, which has a nozzle body, a nozzle inlet opening, a nozzle exit orifice and a substantially planar nozzle mounting surface located on a nozzle flange proximate to said nozzle inlet; (b) reservoir means in fluid communication with said nozzle means for containing said molten metal, said reservoir means having a reservoir outlet opening for flowing said molten metal therethrough and having a substantially planar reservoir mounting surface located proximate to said reservoir outlet which is adpated to mate with said nozzle mounting surface and allow a relative, sliding-type movement therebetween due to a differing thermal expansion of said nozzle means relative to said reservoir means; (c) resilient, heat resistant sealing means located between said nozzle mounting surface and said reservoir mounting surface for minimizing molten metal leakage therebetween; (d) heater means disposed about said nozzle for heating molten metal contained therein; and (e) force means for moving said heater means into contact with said nozzle flange and resiliently urging said nozzle mounting surface toward said reservoir mounting surface to mate said nozzle and reservoir means together.
Claim 3
Dependent Claim
46 words
An apparatus as recited in claim 1, wherein said reservoir mounting surface is an outwardly facing surface of said reservoir means and said nozzle mounting surface is a nozzle body surface facing opposite to the direction of the intended flow of molten metal into said nozzle.
Claim 4
Dependent Claim
108 words
An apparatus as recited in claim 1, wherein said force means comprises: (a) support member which is substantially immobile with respect to said reservoir means; (b) a displacement member which is spaced a distance away from said support member and movable relative thereto; (c) spring means operably connected to said displacement member and said support member for providing a selected force which is adapted to move said displacement member against said heater means, move said heater means into contact with said nozzle flange and urge said nozzle mounting surface toward said reservoir mounting surface; and (d) adjustment means for adjusting said spring means to provide said selected force.
Claim 5
Dependent Claim
99 words
An apparatus as recited in claim 1, wherein said force means comprises: (a) a support member which is substantially immobile with respect to said reservoir means; (b) a displacement member which is movable relative to said support member; (c) pneumatic actuator means for moving said displacement member against said heater means to move said heater means into contact with said nozzle body flange, and for providing a selected force that urges said nozzle mounting surface toward said reservoir mounting surface; and (d) pressure regulator means for controlling a fluid pressure supplied to said pneumatic actuator to adjust said force.
Claim 6
Dependent Claim
132 words
An apparatus as recited in claim 1, wherein said force means comprises: (a) support member which is substantially immobile with respect to said reservoir means; (b) a displacement member which is movable relative to said support member; (c) pivot means connected to said support member for pivoting said displacement member thereabout; (d) pneumatic actuator means for pivoting said displacement member about said pivot means to move a portion of said displacement member against said heater means, move said heater means into contact with said nozzle body flange and provide a selected force that resiliently urges said nozzle mounting surface toward said reservoir mounting surface to mate said nozzle and said reservoir means together; and (e) pressure regulator means for controlling a gas pressure supplied to said pneumatic actuator to adjust said force.
