The following aspects are the common phenomena of poor rolling of Stamping Parts:
1. Foreign bodies are mixed in the surface or inside of the steel plate, the foreign bodies are peeled off, and the rolled materials are in a scar-like state;
2. Scratches (caused by roller surface or foreign matter), corners (20 ~ 30 mm) are deformed or crumpled due to uneven stress, and edges of rolled materials are damaged;
3. As a result of roller sliding, foreign matter enters and bulges out on the back of the roll (foreign matter falls off and disappears);
4. Irregular and damaged edges and bad materials beyond the rules;
5. Roller marks (caused by foreign matter adhering to the roller) and obvious groove marks on the surface depth caused by foreign matter.
After practical use, it is known that scratches (caused by roller surface or foreign matter), bulges (foreign matter falling and disappearing) and roller marks (caused by foreign matter adhering to the roller) are the favorite problems in use.  The solution is simple. The disappearance of foreign bodies is the direct method.
