Title: Mandrel for punching and rolling
Inventor: KAMEMURA YOSHIKI
IPC: B21B25/00
Filed: 1980-08-07
Abstract: PURPOSE: To obtain a mandrel of superior durability by coating carbon steel contg. C at specific % on the surface of a mandrel for rolling mills.  
     CONSTITUTION: Carbon steel which is more likely to form adhesive oxide scale during heat treatment or use than conventional mandrel materials is used for a surface coating material for the mandrel body, and the component range thereof is regulated to ≤0.4% C. Build-up welding is practicable as a coating method, and in short, any method may be used as far as it can provide the coating adhering closely to the mandrel surface. It is necessary to apply this surface coating in a position where damages occur in the mandrel. Thereby, the mandrel of superior durability is obtained and the mandrel of undesirable casting surfaces is sufficiently utilized.
