Aluminum dross is a natural outcome in aluminum melting, which is made by alumina, aluminum nitride, other oxides, nitrides and aluminum.

The actual meaning of dross isforeign matter, dregs, or mineral waste, in particular scum formed on the surface of molten metal.not the waste as one answer guess.

When melting UBC scrap materials, the inside plastic, paint on the outside and the thin layer of aluminum oxide is left on the surface when the aluminum metal collects below at about 1250F.

This dross/slag is from 1/3 ಗೆ 1/2 the weight of the UBC scrap materials melted in ordinary methods and it is not practical to remove the aluminum in the oxide.

If dross is the same as trash, aluminum is not usually recovered, as recovery is labor-intensive. robots cannot separate aluminum from foil-coated paper, except with very complex technology.

The recovery rate of aluminum dross processing will greatly affect the economical benefits in the secondary aluminum industry.

Aluminum dross and aluminum slag processing 3 methods

1. MRM method (Metal recycling machine)

This process is sending the hot aluminum dross generated from aluminium melting furnace to the machine with the dross trolley, with the stirrer mechanical stirring, make the liquid aluminum separated from the dross, adding heating flux into the machine to make the aluminum dross keep the requested temperature.

The liquid aluminium will be extracted from the hot dross can be cast to ingot or remelt in aluminium melting furnace.

The rest of aluminium dross can be further sieved, pulverized, melted and recovered for the second recovery processing.

The recovery rate can be 90% and the burning rate of aluminum can be reduced to 4%.

2. Pressing recovery process method

Press 15Mpa pressure on it, the liquid metal of dross will flow down to the lower container under the pressure; the oxidation of dross that is pressed will be ended, the oxide will be muffled in the metal shell.

ಅದೇ ಸಮಯದಲ್ಲಿ, the metal shell of dross will transfer the heat to the pressure head and dross tray, the cooling water of the pressure head will take away lots of heating, which will make the slag temperature reduced from more than 800℃ to below 450℃, to prevent the oxidation of metal because of high temperature.

3.ALUREC Method

Rotary furnace, Oxygenenrichment natural gas as the fuel, can get to high temperature in a short time.

Liquid aluminum lays down the bottom of the rotary furnace; Non-metallic slag will float on the top of the rotary furnace.

The method is featured with high efficiency, ಕಡಿಮೆ ಶಕ್ತಿಯ ಬಳಕೆ, good running environment.

Pure oxygen will be used as an oxidizer effective to reduce the organic gases generated in the combustion process.

Gas hoods can effectively recover the other dust, with high efficiency, high degree of mechanization and good running environment advantages.

The shortage is the residual aluminum dross needs to be further processed.
