1. Ensure safety: Before disassembly, make sure that the pot helmet furnace is completely cooled to avoid burning yourself. At the same time, wear appropriate protective gloves and masks to prevent dust and debris from entering the body.

2. Cleaning the surface: Before removing the gypsum mesh, the surface at the bottom of the tank helmet must be cleaned to avoid dust and impurities interfering with the work.

3. Cut off the gypsum net: cut the gypsum net into small pieces with pliers or scissors, and then pry it up. If the gypsum mesh is thick, you need to knock the gypsum mesh with a hammer, break it into small pieces and pry it up.

4. Cleaning residue: After removing the gypsum mesh, it is necessary to clean the gypsum powder and sundries left at the bottom to ensure that the bottom is clean and tidy.
