Buy Purity Aluminum Ingot 99.7
Purity Aluminum Ingot 99.7 are divided into three types according to their composition: aluminum ingots for remelting, high-purity aluminum ingots and aluminum alloy ingots; According to the shape and size, it can be divided into bar ingot, round ingot, plate ingot and T-shaped ingot.
Several common aluminum ingots
Aluminum ingot for remelting — 15kg, 20kg, 25kg (≤ 99.80% Al);
T-shaped aluminum ingot — 5kg, 10kg,15kg (≤ 99.80% Al);
High purity aluminum ingot — 10kg, 15kg, 20kg (99.90% ~ 99.999% Al);
Aluminum alloy ingot — 10kg, 15kg, 20kg (Al — Si, Al — Cu, Al — mg);
Plate ingot — 5 ~ 10kg (for plate making);
Round ingot — 30 ~ 60kg (for wire drawing).
Production Process
The production of aluminum ingot is composed of bauxite mining, alumina production, aluminum electrolysis and other production links.
The bauxite is mined first, and then the bauxite powder is produced through water washing, grinding and other processes, and then the alumina is obtained through four complex processes such as roasting. There are three types of bauxite for producing alumina: gibbsite, diaspore and diaspore.
Among the proven global reserves of bauxite, 92% are weathered laterite bauxite, belonging to gibbsite type. These bauxites are characterized by low silicon, high iron and high aluminum silicon ratio, and are concentrated in West Africa, Oceania and central and South America. The remaining 8% is sedimentary bauxite, belonging to diaspore and diaspore type, with medium and low grade, mainly distributed in Greece, the former Yugoslavia and Hungary.
Due to the different characteristics of the three bauxites, various alumina production enterprises have adopted different production processes, mainly including Bayer method, alkali lime sintering method and Bayer sintering combined method. Generally, high-grade bauxite is produced by Bayer process, and medium and low-grade bauxite is produced by combined process or sintering process. Due to its simple process and low energy consumption, Bayer process has become the most widely used method in alumina production, and its output accounts for about 95% of the total global alumina production.
Under the action of strong current, aluminum oxide electrolyzes aluminum metal. This process is called electrolytic aluminum.
Process Description
The aluminum ingot casting process uses aluminum liquid to be injected into the mold. After being cooled into the casting slab and taken out, the injection process is a key step for the quality of the product. The casting process is also the physical process that liquid aluminum crystallizes into solid aluminum. The process flow of casting aluminum ingot is as follows:
Aluminum tapping – slag stripping – weighing – batching – charging – refining – casting – aluminum ingot for remelting – finished product inspection – finished product weighing – Warehousing
Aluminum tapping – slag stripping – weighing – batching – charging – refining – casting – alloy ingot – casting alloy ingot – finished product inspection – finished product weighing – Warehousing
The common casting methods are divided into continuous casting and vertical semi continuous casting
