A NOZZLE FOR DIRECT METAL STRIP CASTING

摘要

PURPOSE: A nozzle for direct casting is provided to remove slag from molten metal using a ceramic filter and to prevent the formation of oxidation due to the infiltration of oxygen. CONSTITUTION: A nozzle for direct casting comprises an inlet(5) through which molten metal is provided, an outlet(9) through which the molten metal is discharged to the surface of a casting roll, a lower filter(10) which is installed under the inlet in order to remove foreign materials from the molten metal, a projection which is formed in the boundary between the inlet and the outlet, and an upper filter(22) which is formed on the top of the projection in order to remove slag.
