AC/DC Electric Drive System Used for Steel Rolling Mill Line

Product Description

Hi, welcome

Features of our driving and automation system:

   DC drive control system adopts Siemens 6RA70 / DCM80 as the core part of adjustment, and high-power thyristor as the power core part that produced with imported production lines, both jointly consist of the motor speed control device by reliable grafting technology, such a device can achieve the world advanced level, and the price is not expensive, has the very high performance/cost ratio. The control system of the current inner ring and the speed outer ring is double-closed by the Siemens full digital control chip. The control system also has the functions of speed regulation feedforward (pre-control), armature current regulation and excitation current regulation, so as to ensure that the control system has the same dynamic performance when the current is discontinuous and continuous, field-weakening and not weakening. The 6RA70/DCM80 control system also has self-optimization and self-diagnosis functions, which greatly reduces the work intensity of debugging and field maintenance personnel.

   AC frequency conversion motor drive with Siemens and other international famous brand inverter as the core element, with advanced control concepts, by various digital processing technologies such as PWM control, vector control and direct torque control, it can perfectly solve various industrial production in the transmission demand. Whether it is a rolling mill, various roller table, chain conveyors, pinch roll or the compound drive of continuous casting and rolling metallurgy equipment, the corresponding solutions can be realized according to the technological requirements.
