As an Aluminum Alloy Ingot Supplier, share with you.
Aluminum ingots have been widely used in many industries and attracted widespread attention. In fact, this is closely related to the superior product performance of aluminum ingots. Let's take a look!
First of all, the aluminum ingot has good process performance. Using the first processing and then spray painting process, the aluminum ingot can be processed into various complex geometric shapes such as flat, curved and spherical surfaces;
In addition, the coating of aluminum ingots is uniform and diverse in color. Advanced electrostatic spraying technology makes the paint and aluminum ingots adhere uniformly, with various colors and large selection space.
Finally, the aluminum ingot is not easy to stain, which is easy to clean and maintain. The non-adhesiveness of the fluorine coating film makes it difficult to attach pollutants to the surface and has good cleanliness.
In addition, aluminum ingots are light weight, good rigidity, excellent durability and corrosion resistance, and are ideal materials.
In addition, the surface of aluminum ingots is not easily corroded due to the dense oxide protective film. It is often used to manufacture chemical reactors, medical equipment, refrigeration equipment, petroleum refining equipment, oil and gas pipelines, etc. Die-casting aluminum ingots should be purified before casting, because primary aluminum contains many other elements, which must be purified. The industry mainly uses clarification, flux, gas and other purification methods, and some use directional solidification and filtration Purification.
Flux purification. Flux purification is to use the flux added to the aluminum liquid to form a large number of fine droplets, so that the oxides in the aluminum liquid are wetted, adsorbed and dissolved by these droplets, and a new droplet is formed on the surface. After cooling, scum is formed and removed.
The purifying flux is composed of a salt having a low melting point, a small density, a small surface tension, a high activity, and a strong adsorption capacity for oxide slag. When using, first put a small piece of flux into the iron cage, and then insert it into the bottom of the mixing furnace to stir back and forth. After the flux is finished, remove the iron cage and let it stand for 5-10 minutes. Remove the surface scum and cast. The flux can also be removed to cover the surface as required.
The production of Aluminum Ingot is composed of bauxite mining, alumina production, and aluminum electrolysis.
Bauxite is first mined, aluminum ore powder is produced through processes such as water washing and grinding, and then alumina is obtained through four complex processes such as roasting. There are mainly three types of bauxite that produce alumina: gibbsite, Hydraulic bauxite, boehmite.
