Smelting aluminum in a rotary furnace is an advanced aluminum resource recycling process that uses the special structure and working principle of the rotary furnace to achieve efficient smelting of aluminum ash or scrap aluminum and aluminum extraction. This process not only improves production efficiency, but also reduces energy consumption and environmental pollution, with significant economic and social benefits.

In the process of smelting aluminum in a rotary furnace, materials containing aluminum, such as aluminum ash or scrap aluminum raked from the smelting furnace, are first put into the high end (kiln tail) of the rotary furnace. These materials are constantly tumbling and mixing in the furnace as the rotary furnace rotates, thereby achieving the initial separation of aluminum from aluminum ash or other impurities. At the same time, by controlling the temperature in the furnace, the smooth progress of the smelting process can be ensured. During the smelting process, cold slag or small raw aluminum may be added as a temperature control agent to adjust the temperature in the furnace to keep it within a suitable range.

As the smelting progresses, the aluminum liquid is gradually separated from the aluminum ash. At this time, the aluminum liquid can be poured out by tilting the rotary furnace barrel. After further cooling and solidification, the aluminum liquid can form aluminum ingots for subsequent use. This process not only realizes the effective extraction of aluminum, but also greatly improves the recovery rate of aluminum.

At the same time, the process of aluminum smelting in a rotary furnace is also significantly energy-saving. When processing hot slag and cold slag, due to the special structure and working principle of the rotary furnace, smelting can be achieved without additional heating devices. This not only reduces energy consumption, but also reduces production costs.

In addition, the process of aluminum smelting in a rotary furnace is also very environmentally friendly. Because it is centralized, the dust generated is easy to collect and treat in a centralized manner, thereby reducing environmental pollution. At the same time, through reasonable material ratio and smelting parameter control, the emission of waste gas and the content of harmful substances can be further reduced to achieve green production.

In summary, aluminum smelting in a rotary furnace is an efficient, energy-saving and environmentally friendly aluminum resource recovery process. It makes full use of aluminum ash or waste aluminum resources to achieve effective extraction and recovery of aluminum. At the same time, through the implementation of energy-saving and consumption-reducing and environmental protection measures, production costs and environmental pollution are also reduced. Therefore, this process has broad application prospects and development potential in the field of aluminum resource recovery. In the future, with the continuous advancement of technology and continuous optimization of processes, the process of rotary furnace smelting aluminum will become more mature and complete, making greater contributions to the sustainable utilization of aluminum resources and environmental protection.
