The application of mold casting powder is usually related to specific production processes and equipment, but can generally be summarized into the following steps:
1. Preparation Stage:
Select the appropriate mold casting powder type and specifications according to production needs, ensuring its quality meets requirements. Simultaneously, prepare other necessary auxiliary materials and equipment.
2. Mixing Stage:
Mix the mold casting powder with appropriate amounts of other additives (such as zinc powder, aluminum powder, etc.) in a certain proportion until homogeneous. The mixing process should ensure no impurities are introduced, and the mixing time and intensity should be well controlled.
3. Addition Stage:
Add the mixed mold casting powder into the mold according to the production process requirements. Add it evenly and in appropriate amounts, avoiding excessive or insufficient addition.
4. Pouring Stage:
After adding molten iron to the mold, perform the pouring operation. During the pouring process, pay attention to controlling the pouring speed and temperature to ensure the quality of the casting.
5. Cooling and Demolding Stage:
After pouring, wait for the casting to cool to a certain temperature before demolding. Care should be taken during demolding to avoid damaging the casting.
