aluminum sheet is the most widely used aluminum product in the market, the quality of aluminum sheet becomes the most important aspect in producing process. For many people do not know how the aluminum sheet is produced, and today let Haomei aluminum to reveal the aluminum sheet production process for you, so that the aluminum production process is no longer mysterious, unlock the mystery of your heart.


1. The first is the production of raw materials, any production is processed from the raw materials, and the raw material of aluminum sheet is aluminum ingots, usually melt the aluminum ingot into aluminum water, and then put the liquid aluminum into the continuous casting machine, Aluminum water through the casting mill for the casting roll, usually the thickness of the casting roll is between 8-10mm, which is the first step in the production of aluminum sheet.
2. And then comes to precision rolling processing by the finishing mill, usually finishing mill mill precision can be control within 0.01mm, then the finish rolling mill is subjected to repeated rolling the casting roll to the desired thickness. This is the second step in the production of aluminum sheet and the most important step.
3. Then comes to the trimming and cleaning processing of the casting roll, trimming is to trim the irregular edge of the roll, and cleaning is due to the rolling mill is about rolling material inside the rolling oil, the surface oil must be clean up.
4. Finally, the annealing and packaging, annealing is placed in a constant temperature annealing furnace for some time, through the high temperature to change the internal grain size of aluminum sheet to obtain a variety of mechanical properties and elongation, and then after the completion of annealing, through the equipment to open processing, then packaging for all kinds of package.

Melting

aluminum Sheet metal can be made from a variety of different metals including aluminum. No matter what type of metal is used, the first step is to melt the metal in a container called a crucible.

Pouring

When the metal is completely melted, it is poured out of the crucible and into a rectangular mold. The metal must be kept hot as it is poured into the mold so that it does not begin to harden outside of the mold.

Pickling

When the metal has cooled completely, it is taken out of the mold. We now have a rectangular block of metal known as an ingot. The ingot is then dipped into a mixture of chemicals to be cleaned; a process known as pickling.

Rolling

Once the ingot has been cleaned, it is put through a press. The press consists of two large rollers that thin out the metal. The press rollers are then moved closer together and the metal is run through again. Ingots may have to be run through the press several times before they reach the desired thickness.

Annealing

As the ingot is run through the press the metal will become increasingly harder. It may be necessary to anneal the metal several times throughout the rolling process. Annealing the metal consists of heating it up and then pickling it again. During the annealing process the metal is only made warm-it is not melted again.

Shipping

After the metal reaches the desired thickness, it is either shipped flat or rolled into a coil. Finished sheet metal is anywhere from .05 millimeters to 15 centimeters thick aluminum Sheet .

Aluminum sheet is any aluminum product that is less than a quarter of an inch thick. Sheet is an essential material for several industries, most notably aerospace and automobile construction. Aluminum sheet is produced through by passing an aluminum ingot through high-pressure rollers until it reaches the desired dimensions. Aluminum sheet is an easily recycled material, and recycling sheet aluminum costs a tenth of the energy needed to produce new aluminum.
