First, the pure aluminum ingots are added to the aluminum alloy melting furnace to melt. These aluminum ingots that become blanks are removed from impurities such as dezincification, titanium and silicon. In this 25 tons of aluminum melting furnace, 24 tons of aluminum can be melted at a time, which requires 3 to For 8 hours, the furnace temperature is 750°C, and the melting point of aluminum is 660°C. During the melting process, samples will be taken and made into samples for testing.
After the molten aluminum is completely melted in the aluminum melting furnace, the configuration of the aluminum alloy is qualified. The molten aluminum is put into the mold through the chute to make aluminum ingots of different specifications, the general size can reach 4.4mx1.4mx0.45m. The large aluminum ingots are transported by the crane to the planer for special use, and the surface is smoothed and enters the next process Process.
The next process is the hot rolling process. The temperature of the rolls is between 455°C and 540°C. After rolling over and over again, the large aluminum ingot is pressed into an aluminum plate with a length of 9 meters and a thickness of 5 cm.
Next, cold rolling is performed to roll the aluminum plate to the thickness required by the customer.
Then carry out trimming treatment.
