For gravity casting, low pressure casting is more conducive to the realization of automatic mechanical production. One worker can operate the machine low pressure pouring machine, the production efficiency is greatly improved, sometimes it can be increased to more than 3 times, and the working conditions are good and the labor intensity is low. So do you know what the aluminum casting processing steps are? What are its processing steps? Next, let’s take a look at the aluminum casting processing steps.
- What is aging treatment? The method of heating the solution-treated sheet metal to a set temperature, releasing it after a certain period of time, and slowly cooling it in the air is called aging. If the aging strengthening is completed at room temperature, it is called natural aging; if the aging strengthening is completed in an environment higher than room temperature and kept for a certain period of time, it is called artificial aging. The aging process is a spontaneous process of the decomposition of the supersaturated solid solution, which can restore the wafers of the alloy matrix to a relatively stable state.
- What is annealing treatment? The process of metal casting aluminum is heated to about 300 ℃, and after holding for a period of time, the process of cooling to room temperature with the furnace is called annealing. During heat treatment, the solid solution will decompose and the second phase points will aggregate, which can eliminate the internal stress of the casting, keep the size of the casting stable, avoid deformation, and enhance plasticity.
- What is solution treatment? The casting is heated to near the melting point of the eutectic, and then kept at this temperature for a long time, and then rapidly cooled, so that the strengthening components are well dissolved, and this high temperature state is maintained to room temperature, this process is called solid solution deal with. Solution treatment can improve the plasticity and strength of castings and improve the corrosion resistance of alloys; usually, the effect of solution treatment is related to solution treatment temperature, solution treatment holding time, and cooling rate.
