Ring Rolling Machine Banning H155/V105

1) Ring Rolling Mill

The horizontal / vertical ring rolling mill is provided for rolling seamless rings at forging temperature.

2) Working Range

Outside diameter of finished ring : 350 - 2800 mm,

Height of finished of ring blank for : 80 - 500 mm,

Mandrel diameter : 170 mm,
