However, this has the following drawbacks. (B) In the process of melting aluminum, so-called burnt residue was generated at about 10% and was treated as industrial waste, but it was also unsuitable for environmental hygiene. (B) In the process of dissolving aluminum, aluminum oxide was generated and the aluminum recovery rate was reduced. (C) The inclusion of the dissolution process in the middle of the production process also prolongs the manufacturing time and is inefficient and uneconomical. (D) The conventional press-molded deoxidized lump had an apparent specific gravity of about 2.2 g / cm 3 , and thus the deoxidation efficiency was poor. (E) Conventionally, aluminum scraps and aluminum alloy scraps were melted as they were, so that the recovery rate of aluminum and aluminum alloys was poor. The present invention has been made to eliminate these drawbacks.

EFFECTS OF THE INVENTION (a) Compared with the conventional production method by dissolution, the present invention eliminates the generation of industrial waste and eliminates the risk of environmental damage. (B) Since the present invention can realize a high specific gravity as compared with the conventional briquette product, the contact area with the molten metal is wide,
The deoxidizing effect was able to be improved. (C) In the present invention, since the melting process can be eliminated in the production process, the production time can be shortened and low-cost production can be realized. (D) In the present invention, since there is no dissolution step in the production process, aluminum is not oxidized due to dissolution, and the recovery rate of aluminum can be increased. (E) The present invention is originally a deoxidized lump for steel makers, but when used as a raw material for an aluminum secondary alloy ingot, the specific gravity is 2.45 g / cm 3 to 2.6 g / cm.
Since it is 3, when it is poured into the molten metal, it easily sinks inside,
Since the amount of oxides is also reduced, the amount of industrial wastes is necessarily reduced, and at the same time, the recovery rate of aluminum and aluminum alloys is improved.
