It is configured to transfer to the charging wait (31).

The operation of the present invention in such a member will be described.

First, the engine block MB is placed on the empty tray T waiting on the charging stand 31 of the charging device unit 3 at the charging stage. As a means for transporting the engine block, a house crane (not shown) is used. This is used.

When the engine block MB is loaded on the tray T as described above, the inlet door 11 and the outlet door 12 are operated by operating the cylinders 13 and 14 at the inlet and outlet sides of the continuous melting furnace 1. After opening, the cylinder 32 of the charging device unit 3 is appeared and operated to push the tray T into the continuous melting furnace 1, where a plurality of trays previously loaded are stored in the continuous melting furnace 1. While the T) is loading the engine block MB, the tray T loaded at the inlet while being aligned in a line with each other on the transport loading stand 2 pushes the tray at the inlet side to the outlet side. While charged, the tray located on the outlet side is pushed out and discharged to the take-out device 4 through the outlet.

As described above, when one tray T is charged into the inlet of the continuous melting furnace 1, the trays T located at the outlet side are discharged step by step one by one, and are stacked on the transfer loading table 2 as described above. The engine block MB loaded on the tray T transported step by step by charging one by one is configured to be heated to a temperature at which aluminum alloy can be completely dissolved while being transferred step by step from the inlet side to the outlet side. As the aluminum alloy contained in the engine block MB is completely dissolved on the tray T discharged to the outlet, it flows to the bottom of the continuous melting furnace (1) and the melting point is higher than that of the aluminum alloy, so that only the undissolved iron scrap remains. Will be.

On the other hand, the aluminum is heated and melted in the continuous melting furnace (1) to fall to the floor flows to the tap opening 17 by the inclined bottom 19 inclined toward the tap (17) side is discharged to the outside while collecting the aluminum molten metal Work is done naturally.
