Two, two- high rolling mills have been used in the tests. In the larger, the rolls of 250 mm diameter and 150 mm length are made of D2 tool steel, hardened to Rc = 64. The mill is driven by a 30 kW, constant torque DC motor, whose speed is controlled by a TYRAK controller. The speed is continuously variable, up to a maximum of 3 m/s.
