Measures to prevent oxidation and slag inclusion: Strictly control the smelting process, accelerate smelting, reduce oxidation, and thoroughly remove slag. Aluminum magnesium alloy must be melted under a covering agent. The furnace body and tools should be clean and free of oxides, and should be preheated. The paint should be dried after use. The designed casting system must have stable flow, buffering, and slag skimming capabilities. Adopting an inclined pouring system to ensure stable liquid flow and prevent secondary oxidation. The selected coating has strong adhesion, and slag is formed in the casting during the pouring process without peeling.

Measures to prevent hot cracking: In actual pouring systems, local overheating should be avoided to reduce internal stress. The mold and core slope must ensure the above 5 °, the inverted riser can be pulled into shape during solidification, and the sand core can replace the metal core if necessary. Control the thickness of the coating to ensure consistent cooling speed of the casting. Choose the appropriate mold temperature based on the thickness of the casting. Refine the alloy structure and improve the hot cracking ability. Improve the structure of castings, eliminate sharp corners and sudden changes in wall thickness, and reduce the tendency for hot cracks.

Measures to prevent loose production: Reasonable riser setting to ensure solidification and shrinkage capacity. Reduce the working temperature of the metal mold appropriately. Control the thickness of the coating to make the thick walls thinner. Adjust the cooling speed of each component of the metal mold to provide greater cooling capacity for the thick walls of the casting. Reduce the metal pouring temperature appropriately.
