As 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.
