FIELD: process engineering.
SUBSTANCE: invention relates to metal forming and may be used at tube hot rolling mill stands. Proposed method comprises piercing the sleeve on mandrel in rolls with conical inlet and outlet and riser pad there between. Note here that mandrel front plane is arranged in roll riser pad. Distance between rolls at the point rolls break off rolls in outlet cone is kept constant while mandrel work section length equals that of outlet cone section. Arrangement of mandrel front plane in roll riser pad, billet free deformation (primary gripping) is executed solely in disk mill roll inlet cone while deformation of wall and roll diameter rising is performed in outlet cone.
EFFECT: higher process efficiency.
