Description

Aluminum molten metal transfer device {DEVICE FOR TRANSPORTING ALUMINIUM MOLTEN METAL}

The present invention relates to a molten aluminum transport device, and more particularly, to a molten aluminum transport device for transporting molten aluminum accommodated in a melting furnace to a casting machine.

In general, aluminum has a specific gravity of 2.7, and is a light metal that is 1/3 lighter than iron having a specific gravity of 7.9.

Among these aluminum manufacturing processes, aluminum scrap using waste resources is used as a melting raw material in the aluminum melting process.

Aluminum scrap refers to the compression of waste aluminum such as building materials and cans in the form of blocks.

After melting the aluminum melting raw material in the melting furnace, the aluminum molten metal accommodated in the melting furnace is transferred to the casting machine by the aluminum molten metal conveying device.

However, since the conventional aluminum molten metal transfer device is manufactured in one frame, it is difficult to partially repair the device when a problem such as damage occurs, and thus the repair period becomes longer.

In particular, when continuous operation is performed, it is very important to reduce the time required to repair the equipment when a problem occurs. Since the conventional aluminum molten metal transfer device is manufactured in one piece, it becomes more difficult to reduce the repair time when a problem occurs.

An object of the present invention is to provide an aluminum molten metal transport device that can shorten the time required to repair the aluminum molten metal transport device as much as possible and minimize repair costs through partial repair.

An aluminum molten metal transport device according to an embodiment of the present invention is installed between a melting furnace and a casting machine to transport the molten aluminum accommodated in the melting furnace to the casting machine.

The molten aluminum transport device may include a unit transport block each having a transport passage for transporting the molten aluminum, and being separately manufactured and assembled into a plurality of units.

It may include a unit shell having a ruler cross-sectional shape and forming an outer surface.

At both ends of each unit shell, unit assembly flanges for assembling and coupling with the neighboring unit shell are formed to protrude outward of the unit shell, and the unit assembly flange has a fixed coupling hole for fastening with the neighboring unit assembly flange and bolts. A plurality may be disposed at intervals.

A cover for covering the upper portion of the unit transfer block may be installed at the upper end of the unit transfer block.

At the upper end of each unit transport block, an upper flange is formed to protrude outward of the unit block for coupling with the cover, and a plurality of upper coupling holes for fastening by the cover and bolts may be arranged at regular intervals in the upper flange.

A unit refractory material for protecting the unit transfer block from the high temperature of the aluminum molten metal may be installed on the inner surface of each unit shell.

A unit insulating material for insulating the molten aluminum may be installed between the unit shell and the unit refractory material.

According to the embodiment of the present invention, when damage or a problem occurs in the aluminum molten metal transport device, partial repair that can be assembled immediately after removal of only a part of the damaged or problematic part is possible, thereby reducing the time required for repair as much as possible. and can also minimize maintenance costs.
