CENTRIFUGAL CASTING APPARATUS FOR A MARINE SCREW PROPELLER, USING A MOLTEN METAL INJECTION DEVICE FOR SUPPLYING A FIXED QUANTITY OF MOLTEN METAL INTO A CENTRIFUGAL CASTING MOLD

摘要

PURPOSE: A centrifugal casting apparatus for a marine screw propeller is provided to reduce casting failures by employing a molten metal injection device, a centrifugal coating mold, and a transfer device.;CONSTITUTION: A centrifugal casting apparatus for a marine screw propeller comprises a molten metal injection device, a centrifugal coating mold(200), and a transfer device(300). The molten metal injection device carries a fixed quantity of molten metal from a melting furnace to the centrifugal coating mold. The centrifugal coating mold is formed under the molten metal injection device and produces a screw propeller through centrifugal casting. The transfer apparatus separates the upper mold from the centrifugal casting mold and takes the completed screw propeller from the lower mold out.;COPYRIGHT KIPO 2011
