How to do a good job in the quality control of metal barrels?
Metal barrels are prone to react directly with chemical elements in the air, resulting in rust and other situations. Galvanized drums have a protective layer that can increase the service life to a limited extent, while metal drums have a shorter service life and are prone to rust. The rusted metal bucket can be removed by brushing as follows: 1. Pour 20 grams of vinegar into a hot metal bucket, brush with a hard brush while burning, drain the dirty vinegar and wash it with water. 2. Put a little salt in the pot, fry it yellow, wipe the pot, then clean the pot, add water and 1 tablespoon of oil to boil, then pour it out and wash the pot. 3. The tea residue is rust-proof.

The metal barrels are welded in the places required by the drawings and process regulations and constructed in strict accordance with the welding process regulations to prevent welding deformation. 4. When the metal barrel needs to be polished or drawn after welding, it must be kept on the same plane as the original metal material (do not grind out depressions). When polishing and drawing, special attention should be paid to the metal material not to be over-burned. (The material will be deformed and will not shine after it has been burned.) After the metal barrel is processed, it must be packaged after being accepted by the inspector to prevent the outer surface from being scratched and bruised.
