There will be various problems in the production process of aluminum alloy die castings. How to solve such problems? Let's focus on a few aspects below:

    The method of judging the inclusion problem of aluminum alloy die castings is to see different points or holes in the processed castings, such as non-specification, size, color and height. The main reasons for this situation are as follows: the charge used in the production contains too much recharge material, which affects the quality of the casting; the alloy liquid is not refined, which affects the quality; part of the slag is brought into the spoon when the liquid is taken and poured; paint or crucible The graphite in the medium enters the molten metal; the temperature during heat preservation is too high and the duration is long, which affects the processing of castings.

    Now that the cause of the inclusion problem in aluminum alloy die castings has been found, the solution has become very simple. In the production of castings, attention should be paid to the use of clean alloy materials, and timely cleaning of the dirt in the return charge; the alloy liquid used for processing should be refined and the slag should be removed; when taking the liquid, the liquid level should be opened to avoid mixing slag and oxide scale; workers Pay attention to cleaning the cavity and pressure chamber; also control the holding temperature and reduce the holding time.
