2024 Labor Day Holiday Notice Dear friends: The long-awaited Labor Day is finally here. Longhua Technology wishes everyone a happy holiday! At the request of the State Council, the May Day holiday period is: 5 days off from May 1st to May 5th, with working hours on April 28th (Sunday) and May 11th (Saturday). Longhua Technology warmly reminds our respected new and old customers: The May Day holiday is approaching. In order to ensure that your company's production can continue smoothly after the holiday, please put the following things in place before the holiday: 1. For customers who need to shut down the furnace during holidays, please be sure to clean the aluminum liquid in the crucible before cooling the crucible; if there is a lot of aluminum liquid remaining in the crucible, the solidified aluminum liquid will easily expand the crucible when the furnace is opened again. crack; 2. If the customer intends to keep the stove warm during the holidays, please also set the heat preservation temperature above 650 degrees. 3. For customers who start the furnace again after holidays, please repeat the initial preheating process for the crucible, empty the crucible, and preheat for a longer time than the initial preheating. 4. When adding materials after the crucible is preheated, please be sure to pay attention. The ingots must be placed vertically into the crucible, and cannot be placed too much or too tightly at one time to avoid cracking the crucible.

Pores and bubbles: Problem description: Magnesium alloy easily absorbs gas in the liquid state, causing pores or bubbles on the surface of the casting, affecting product quality. solution: Reduce gas trapping and bubble generation through improved gating system design. Optimize the pouring process parameters, control metal temperature and pressure, and reduce gas inclusions. Use appropriate degassing treatment methods, such as vacuum degassing or gas dissolving agent treatment, to reduce the formation of pores. Structural distortion and deformation: Problem description: Magnesium alloy has high thermal conductivity and shrinkage rate, which can easily cause structural distortion and deformation of castings during the cooling process. solution: By optimizing mold design and process parameters, the cooling rate and temperature distribution are controlled to reduce the thermal stress of castings. Use an appropriate mold cooling system and cooling medium to balance the cooling rate and avoid deformation of the casting caused by too fast or uneven cooling. Use subsequent heat treatment processes, such as heat treatment or aging treatment, to reduce the internal stress of the casting and improve the dimensional stability. Hot cracking and cold cracking: Problem description: Magnesium alloys may produce hot cracks or cold cracks during the casting and cooling process, which affects the strength and durability of the product. solution: By controlling the temperature and cooling rate of the metal, we can avoid excessive or uneven shrinkage of castings during the cooling process and reduce the occurrence of hot cracks. Use appropriate mold preheating and preheating control to reduce the temperature gradient between the mold and the casting to prevent the occurrence of cold cracks.
