FIELD: process engineering.
SUBSTANCE: mandrel is mounted on hollow rod with feed tube arranged there inside. Better internal cooling of mandrel via circulation of coolant and coolant flows separation to impart them different rates results from arrangement of tapered plug in feed tube. Note here that said plug is arranged asymmetrically with specified eccentricity of ε=0.1*0.3 relative to feed tube and mandrel.
EFFECT: wear-resistant mandrel for piercing mill stand.
