Smelting production is a large part of the production of energy and materials in the aluminum processing industry. During the smelting process, how to increase efficiency, reduce energy consumption, and impact on the environment through technological means has become a highly concerned and important work for aluminum processing companies.

Recently, Nanhai Aluminum Profile Industry Association has invited two well-known experts in the industry to explain the technology of aluminum alloy melting environmental protection and energy saving for more than 60 aluminum profile enterprises. These two experts are respectively the chairman of Suzhou Boeng Furnace Technology Co., Ltd., Yu Zhihua, expert of the Expert Committee of Nanhai Aluminum Profile Industry Association, and any family member of the technical center of Guangdong Jianmei Aluminum Profile Factory Co., Ltd.

Experts gave detailed explanations on the current status and progress of aluminum smelting technology, smoke dedusting and desulphurization technologies for smelting furnaces. In view of the difficulties encountered in the current energy saving and emission reduction of aluminum profiles, the two experts also conducted comprehensive answers through examples of stove modifications and equipment upgrades.

Experts believe that in recent years, the development of aluminum furnace equipment has the following characteristics: the direction of equipment to large-scale development; increased use of hydraulic tilting furnace; molten pool with diversified refractory materials, all-in-one lining applications increased year by year; furnace door opening width plus Large; regenerative burner system into a common configuration of the furnace; a large number of magnetic stirrer applications; basic dust collection and flue gas treatment system; electrical control system widely used PLC control.

During the meeting, experts also summarized the energy-saving technologies of aluminum smelting. These measures include: Efficient charging operation is beneficial to increase equipment productivity and save energy; long flame, strong flame stiffness and high flame ejection speed, The impact melting can increase the melting speed and reduce the energy consumption. The fuel atomizer can improve the oil atomization effect to save energy. The timely adjustment of the flame size during the melting cycle can significantly reduce the energy consumption; shorten the refining, slag, insulation and other process operating time. Advantageous to energy saving; the use of magnetic stirrer can effectively improve the melting capacity, and thus save energy; increase the transfer rate of liquid aluminum can significantly save the total energy consumption.

For this special lecture, the participating companies gave a high evaluation.

Lan Anying, the quality inspection manager of Huahao Aluminum Materials Co., Ltd., believes that fused casting is a problem in the aluminum processing and production process. The energy consumption in the production process is relatively large. If the production process is not well controlled, the environment will be greatly affected. The contents discussed in this lecture are closely related to the production of the enterprise. The theory and philosophy are forward-looking, represent the international and domestic technological development trends, and through the exchanges with experts, the new development direction of the casting equipment and technology is known. Equipment upgrades and technological transformation have laid a good foundation.

This lecture attracted many companies to participate, among them there are many other provincial enterprises. Zhang Zaiyou, sales manager of Shandong Huate Magnetoelectric Technology Co., Ltd. stated that Nanhai, Guangdong is a well-known aluminum industrial base in China, gathering more advanced domestic technologies and talents, representing the development direction of domestic aluminum industry, and participating in Such lectures can understand the relatively new development direction of the industry, and exchanges with peers can also benefit a lot of them.

Su Tianjie, secretary general of the Nanhai Aluminum Profile Industry Association, later concluded that Nanhai is a well-known aluminum industrial base in the country. Implementing energy-saving and emission-reduction measures is of great significance to environmental protection and the promotion of recycling economy development. The recent plan of revitalization of the non-ferrous metal industry promulgated by the State Council also explicitly mentions that we must focus on accelerating the elimination of outdated production capacity and increasing the intensity of technological transformation to promote the structural adjustment and optimization upgrade of the non-ferrous metal industry. The technical committee of Nanhai Aluminum Profile Industry Association took this as an opportunity to specially invite renowned experts in the field of casting and in-depth analysis of the energy-saving technologies for casting processes, hoping to promote the aluminum profile enterprises to strengthen technological transformation of various production processes and equipment. To achieve environmental protection and energy conservation, and promote the sustainable and healthy development of the industry.
