Title:
SYSTEM FOR PRESSURIZING MOLTEN METAL AND CONTINUOUSLY SUPPLYING IT, AND METHOD FOR MANUFACTURING CONTINUOUS METAL PRODUCT
Document Type and Number:
Japanese Patent JP2005324256
Kind Code:
A
Abstract:

To provide a continuous pressure type molten metal supply system and a method therefor to manufacture continuous metal products.

A molten metal supply system 90 includes a plurality of injectors (100) each having an injector housing 102 and a reciprocating piston 104. A molten metal supply source 132 is in fluid communication with the housing 102 of each of the injectors 100. The piston 104 is movable through a first step of allowing molten metal 134 to be received into the housing 102 from the molten metal supply source 132, and a second step of supplying the molten metal 134 from the housing 102. A pressurized gas supply source 144 communicates with the housing 102 of each of the injectors 100 through respective gas control valves 146, and in fluid communication with the housing 102. A molten metal supply system 90 communicates with a discharge manifold 140 having a plurality of outlet dies 404, and capable of manufacturing the continuous metal articles such as tubes, bars, ingots, and continuous plates.
