Procedure to remove a major portion of molten metal of a melting tank metal through an opening efflux incorporated in the bottom surface thereof, a deposit of metal melt and a flow chart of the major operations for carrying out said method

摘要

A method of discharging molten metal from a melting chamber through an outlet (7) in lasuperficie below (3) of the chamber, comprising: providing a downflow metal (17) leaving the chamber in a point which is lower quesu input to the outlet (7) and above the bottom surface (3) of a section of the chamber in which seencuentra outlet (7), wherein the metal flow (17 ) moves along said bottom surface of chamber (3), rises up higher than the input to the outlet (7) aPoint, and sieved through said outlet (7) flows downstream metal and ascending (17) are divided by a wall (5), unaseparacion provided between a lower end of said wall (5) and the bottom surface of chamber (3), queconecta flows down and bottom metal (17); characterized queantes begins downloading, the input to the outlet (7) is raised above its initial position inthe bottom surface of chamber (3) through the wall (5), determining the height of said wall (5 ) laelevacion entry into the outlet (7), and the raised position is maintained until a greater proportion DEMETAL is downloaded from the camera; then yrestaurar the initial position of the input to the outlet (7), leaving a small proportion of metalque remaining inside the camera.
