The raw materials used in aluminum alloy wheels are aluminum, so aluminum fluids are needed during the casting process. The main ways to obtain aluminum can be divided into two types, one is obtained by the manufacturer directly, and the other is melting and melting. Get aluminum ingot. Comparing these two methods of acquisition, I believe that the aluminum liquid obtained through the manufacturer can shorten the cycle of refining to a certain extent, reduce the consumption of metal, reduce energy consumption, and increase labor productivity. However, in this way, it is necessary to make better requirements for transportation. For the choice of dry transportation vehicles, vehicles with insulation must be selected, and the aluminum liquid required directly should be directly transported to the workshop of production casting. At the same time, because of a large amount of aluminum liquid, it is also a big problem in the supply of aluminum fluid. The two major problems in reality make most companies choose to use direct banyan refining aluminum ingots to obtain aluminum liquid. This method can also be controlled by the number of aluminum fluids.
