Keywords: IGBT, IEGT, 3-level in verter, mill main drives, Fixed Pulse Pattern, hot strip mill INTRODUCTION DC drives and cycloconverters have been used in rolling mill applications for many years. The appearance of the IEGT (Injection Enhanced insulated Gate bipolar Transistor) or IGCT/GCT made the large PWM drive system practical.
In this work, the Hopf bifurcation of the main drive delay system of rolling mill is controlled and analyzed by designing a nonlinear controller. The time-delay is selected as a bifurcation parameter, and the following conclusions are obtained through analysis: (1) in the absence of state feedback control, the system will generate the Hopf bifurcation at the expense of its stability when the ...
Rolling mills may be classified according to the number and arrangement of the rolls. (a): ... Such an arrangement is used in mills through which the bar passes once and in open train plate mill. 2: ... These are more expensive compared to the non reversing rolling mills. Because of the reversible drive …
Tandem rolling is also known as continuous rolling in which two or more set of four high rolling mill arranged in a series in which each set is called stand. These stands are arranged so they can roll the work piece in decreasing cross section. It is used for rolling thick work piece in single pass.

Figure II. Drive system for three driven roller Mills. Gearboxes are flange mounted to the bearing block with the help of a mounting spacer. The gearbox have hollow output shaft with internal spline or hollow square (to customer specifications) to match the roller shaft. This arrangement simplifies the drive mounting by avoiding,.Torque arm.
