Manufacturing device for cast bar and tube and metal materials obtained by the device

Abstract

A manufacturing device for a cast bar and tube includes a molten metal furnace for holding a dissolved casting material, a hollow tube having a penetrating part of molten metal for penetrating molten metal, a depressurization device for reducing the pressure, a connection member for connecting the hollow tube to the depressurization device, and an open/close type valve member installed on the connection member. The penetrating part of molten metal is depressurized by switching the valve member to the closed state to reduce the pressure in the side of the depressurization device from the valve member using the depressurization device and inserting an opening of the hollow tube into the molten metal furnace as well as by switching the valve member to the open state.

1 . A manufacturing device for a cast bar and tube comprising:
 a molten metal furnace for holding a dissolved casting material;   a hollow tube including a penetrating part of molten metal for penetrating molten metal, the hollow tube can be freely inserted into and withdrawn from the molten metal furnace;   a depressurization device to generate a negative pressure;   a connection member of connecting the hollow tube to the depressurization device; and   an open/close type valve member installed on the connection member,   wherein the penetrating part of molten metal is depressurized by switching the valve member to the closed state to reduce the pressure in the side of the depressurization device from the valve member using the depressurization device and inserting an opening of the hollow tube into the molten metal furnace as well as by switching the valve member to the open state, thereby penetrating molten metal into the penetrating part of molten metal under reduced pressure to solidify the penetrated molten metal in the penetrating part of molten metal to manufacture a long belt-like member.
