  • Composite nozzle assembly for conducting a flow of molten metal in an electromagnetic valve
    Patent number: 5186886
    Abstract: A composite nozzle assembly for conducting a flow of molten steel in an electromagnetic valve is provided which comprises an inner nozzle shell formed from a ceramic material having high erosion-resistance but which undergoes internal tensile stresses of a magnitude sufficient to promote cracking when subjected to the thermal stresses caused by the flow of the molten metal, in combination with an outer nozzle shell that contains and closely engages the inner nozzle shell for applying a compressive load to the inner nozzle shell upon the initial flow of the molten metal through the shell in order to counteract the thermally induced tensile stresses and thereby prevent cracking.
