Zhongfu High-Precision Aluminum Co., Ltd. Realizes Fused Aluminum Liquid Instead of Fused Ingots

Recently, after nearly one year's continuous trials, Zhongfu High-Precision Aluminum Company's casting plant successfully transformed the original “reclamation ingot” into the furnace through the technological innovation and equipment transformation. Compounded aluminum liquid "into the furnace. Through the operation mode upgrade, it is of great significance to improve the production efficiency of aluminum scrap into the furnace and reduce the production cost. According to preliminary calculations, if all the reconstituted wastes are put into the furnace in liquid state, the cost of gas can be reduced by 300,000 yuan throughout the year.

In strengthening the management of production organization, especially the optimization of the production and operation mode of the two-chamber furnace, Zhongfu High-Precision Aluminium Co., Ltd. conducted a bold experiment. Two-compartment furnace is an important project for the high-precision aluminum to digest aluminum waste. The decomposed waste is the milling waste generated during the milling process of the slab ingots, and the waste after melting in a two-chamber furnace. According to the previous production process, after the “reforming molten aluminum” is discharged from the two-compartment furnace, it must be cooled in the desiccating box to a “reclamation ingot” before it can be used as a solid material in the casting process. Add to the smelting furnace for smelting.

In order to increase production efficiency and reduce the gas consumption cost of the secondary melting of the “reclamation ingot”, the casting plant has tried for over one year to overcome various problems, successfully added the aluminum package preheating device, and adjusted the baking furnace process. Finally, it realized the production mode that the complex waste was discharged directly from the two-compartment furnace and passed through the aluminum package into the smelting furnace in the liquid state. After the operation mode is upgraded, on the one hand, the gas consumption cost of the secondary melting of the “reclamation ingot” can be greatly reduced; on the other hand, compared with the “reinjection ingot”, the decomposed waste is put into the furnace in the liquid state, and the bottom of the furnace is The impact force is almost zero, which extends the operating life of the furnace. At the same time, the reintroduced waste is directly introduced into the furnace, which reduces the intermediate stages of solidification of the compound liquid and reduces the cost of manpower and auxiliary materials.
