Der Produktionsprozess von Aluminiumspulen

Aluminiumspule is a metal product that is subjected to flying shear after injection molding and angle drawing in a casting and rolling mill. Es wird häufig in elektronischen Geräten verwendet, Verpackung, Ingenieur Konstruktion, mechanische Ausrüstung und andere Bereiche. Was ist also der Produktionsprozess dieses Produkts?? Lassen Sie mich unten mit Ihnen teilen.
1. Smelter processing
Aluminiumbarren können in drei Typen unterteilt werden: remelting scrap aluminum, high-purity scrap aluminum and aluminum alloy profile ingots according to different components; according to their appearance and specifications, they can be divided into bar ingots, round ingots, plate ingots, T-shaped ingots, etc. Aluminum is a silver-colored metal material that ranks third in composition after oxygen and silicon in the earth’s surface. The density of aluminum is relatively small, only 34.61% of iron and 30.33% of copper, so it is also called non-metallic material. It is a rare metal second only to steel in production and use in the world.
2. Casting/hot rolling
The liquid metal is fed from the stationary furnace according to the launder into a headbox with a controllable liquid level aspect ratio. A runner is set up at the bottom of the front box, so that the liquid metal enters the nozzle through the regulator, and the metal material is evenly distributed to the specified total width. The liquid metal is discharged from the casting nozzle and is in contact with the refrigerated roll surface of the casting and rolling mill. Then after straightening, unwinding into a disk. During casting and rolling, there is a ladder-like section between the two rolls. In this section, two processes of casting and rolling are carried out instantaneously. Deswegen, the length of the casting and rolling zone, the casting temperature, the cooling and forging rates, and the instantaneous liquid of the crystal must be strictly controlled. Factors such as the demand for metal and the rising working pressure of liquid metal can make casting and rolling work normally.
3. Aluminum coil cold rolling
The difference between cold rolling and hot rolling is that cold rolling is rolling at work hardening temperature, while hot rolling is rolling above work hardening temperature. Each has advantages and disadvantages. Cold rolling mainly solves the materials that cannot be thermally strengthened. Allgemein, the surface layer is highly specified, and thin materials such as single zero foil and double zero foil can only be rolled by cold rolling; while hot rolling is mainly to produce blanks for cold rolling. Zweitens, many materials need to have high corrosion resistance, and these functions such as fatigue relief and strong ductility also need to be obtained by hot rolling.
4. Flat packaging
The aluminum coil leveling packaging is essentially cold rolling with a small reduction rate (0.3%-3%). Flattening can improve the shape of the plate and increase the verticality of the strip. According to the adjustment of the reduction rate of the flattening, the physical properties of the hot-rolled strip can be changed within a certain range. Leveling according to a double-click mouse rack or triple-sound card rack also enables a large reduction rate, facilitating the manufacture of thin tin-plated boards. After heat treatment, general strips, tin-plated plates, automotive sheets, etc. need to be leveled.
