MOLTEN MAGNESIUM SUPPLYING DEVICE

摘要

PROBLEM TO BE SOLVED: To obtain stable die casting work having good workability on a maintenance by stabilizing a molten metal supplying quantity. SOLUTION: A molten metal transporting tube 52 which is provided with an electromagnetic pump 50 and is communicated with a molten metal furnace controlled to the fixed molten metal surface at the suction side of this electromagnetic pump 50 and with a furnace part 2 as a bending tube 3 bent upward at the molten metal discharging side is provided. The molten magnesium M in the molten metal furnace is supplied into an injection sleeve 51 through the molten metal transporting tube 52 and a funnel part 2 by driving the electromagnetic pump 50 under the state of filling gas G for oxidize-resistance into the funnel part 2. In a part of the bending tube 3 in the molten metal transporting tube 52, the tube itself is formed as a constricting shape to arrange a throttle part 4 influencing the pressure loss effect.
