Aluminum ingot is the raw material for smelting and casting pure aluminum and aluminum alloy products (such as aluminum profiles, aluminum alloy castings, etc.). The production of aluminum ingots is composed of bauxite mining, alumina production, aluminum electrolysis and other production links. Due to the different characteristics of the three kinds of bauxite, aluminum ingot manufacturers have adopted different production processes in production. There are mainly three methods: Bayer method, soda lime sintering method and Bayer-sintering combined method. Usually high-grade bauxite is produced by Bayer method, and low-grade bauxite is produced by combined method or sintering method.
The raw material in our daily industry is called aluminum ingot, which should be called "aluminum ingot for remelting" according to national standard (GB / T 1196-2008), but everyone is used to "aluminum ingot". It is produced by electrolytic method using alumina-cryolite in aluminum ingot factory. After aluminum ingots enter industrial applications, there are two major categories: cast aluminum alloys and deformed aluminum alloys. Cast aluminum and aluminum alloys are castings that produce aluminum by casting; deformed aluminum and aluminum alloys are processed products that produce aluminum by pressure processing. The raw material quality of adc12 aluminum ingot directly affects the quality and production efficiency of aluminum alloy die casting. Good raw materials can reduce the wear of the mold, extend the life of the mold, reduce costs, and improve production efficiency.
Aluminum ingot china is divided into three types: aluminum ingot for remelting, high-purity aluminum ingot and aluminum alloy ingot according to different components; it can be divided into bar ingot, round ingot, plate ingot and T-shaped ingot according to shape and size Wait a few. A suitable temperature for the price of aluminum ingots will have a very large impact on the quality of aluminum alloy die casting. Too high or too low temperatures will cause unpredictable damage. Reasonable mold design, timely nitriding improves the hardness and smoothness of the mold work belt, reduces the number of mold repairs, reduces non-ergonomic time, improves product quality, and reduces scrap rate, which is very important to maximize output.
Die-casting aluminum ingot is one of the most advanced metal forming methods. It is an effective way to achieve less chip and no chip. It is widely used and developed quickly. Aluminum ingot manufacturers die-casting aluminum ingot alloys are no longer limited to non-ferrous metals such as zinc, aluminum, magnesium and copper, and are gradually expanding the use of die-casting aluminum ingot cast iron and steel castings. The size and weight of die-cast aluminum ingots depend on the power of the die-cast aluminum ingot machine. Die-casting aluminum ingots, Wang Wenshengyi means that under the action of high pressure, liquid or semi-liquid metal fills the die-casting aluminum ingot cavity at a relatively high speed, and forms and solidifies under pressure to obtain castings.
Aluminum ingot is one of the original materials commonly used in modern industry. Its production and casting needs use die-casting aluminum ingot machine, which is a common method in modern casting process, but it also has some shortcomings. There are stomata.
The die-casting aluminum ingot machine is the primary mechanical equipment for producing aluminum ingots, but in order to avoid the shortage of castings, it should continue to innovate. The main feature of die-casting aluminum ingots is that the molten metal fills the cavity under high pressure and high speed, and is formed and solidified under high pressure. The disadvantage of die-casting aluminum ingots is that: because the molten metal fills the cavity under high pressure and high speed It is inevitable that the air in the cavity will be wrapped inside the casting to form the pores under the skin, so aluminum alloy die-casting aluminum ingots should not be heat-treated, and zinc alloy die-casting aluminum ingots should not be sprayed on the surface. Otherwise, when the pores inside the casting are heated by the above treatment, they will expand due to heat and cause the casting to deform or blister.
The die-casting aluminum ingot is a metal-type pressure casting performed on a die-casting aluminum ingot machine, and is now a casting process with high production efficiency. Aluminum ingot factory die-casting aluminum ingot machine is divided into hot chamber die-casting aluminum ingot machine and cold chamber die-casting aluminum ingot machine. The hot chamber die-casting aluminum ingot machine has a high degree of automation, less data loss, and the production efficiency is higher than the cold chamber die-casting aluminum ingot machine. However, due to the heat resistance of the machine parts, it can only be used for low melting points such as zinc alloys and magnesium alloys. The casting of the data is produced.
The scope of use is very wide, mainly in the automotive, furniture, lighting, and other hardware accessories industries. Aluminium ingots are no longer limited to the automotive industry and the exterior industry as the technology and usage environment change. Dozens of industries such as equipment, wall clocks, cameras and household hardware, including: auto parts, furniture accessories, bath house accessories (bathroom), lighting parts, toys, shavers, tie clips, electrical and electronic parts, belt buckles, Case, metal buckle, lock, zipper, etc. In the technology of die-casting aluminum ingots, new technologies such as vacuum die-casting aluminum ingots, oxygenated die-casting aluminum ingots, precision speed dense die-casting aluminum ingots, and the use of soluble cores are presented.
