METHOD FOR PRODUCING HOLLOW BODIES ROTATION WITH SHAPED LATERAL SURFACE (TRACKTOR ROLLER TYPE), METHOD OF SURFACE HEATING OF THE HEADPHONE PREPARATION IN THE HDR INDUCTOR AT THE EMPTY RECEPTION WITH A COOLED CORE PREVENTING THROUGH THE HEATING OF THE HEADING PACKAGE, WITH THE FOLLOWING ROLLING OF THIS PREPARATION IN THE CENTERS BETWEEN TWO CONTINUOUS AND ROTATING PROFILE ROLLS Russian patent published in 2017 - IPC B21H1/00 B21H7/00 B23P15/22 

FIELD: transportation.

SUBSTANCE: surface heating of the workpiece of the tractor compactor in the HDTV inductor and subsequent rolling of the workpiece in the centers between two approaching and rotating profile rolls. In this case, the surface heating of the billet is carried out to a temperature of 1200±50°C to a depth 30 mm on a hollow mandrel with a cooled core, preventing through heating of the workpiece. Rolling of the workpiece is carried out in profile rolls rotating at a speed of 35 rpm.

EFFECT: expanding technological capabilities.
