For the success of rolling mills, the main and auxiliary drives, in combination with the mill stand main motors, play a key role. The crucial demands placed on drives and motors technology are therefore high-dynamic, high- accurate response and high-stability of the control system and high overload capability, smooth running, maximum availability, service friendliness, and seamless integration into higher-level automation systems. As market leader with numerous reference installations and decades of experience, Siemens has accumulated extensive expertise in right drive systems.
The frequency converter family Sinamics meets the trends in rolling mill drive technology, such as highly flexible drive solutions and scalable power demand. Sinamics is based on a common platform concept: The same hardware and software components are used for the same functions over a wide spectrum. Functions such as drive control, operator control, diagnostics and communication with higher level controllers are implemented in a standard fashion across the whole of the Sinamics family. This makes it easier to handle the drive technology and ensures valuable synergies within the overall Sinamics portfolio: The time and resources required for training are reduced. Not only this, support, service & maintenance and spare parts management are also simplified.
For rolling, leveling, shearing and strip
transportation drives in the metals industry
the blue-marked systems S120CM, SM150 and
SL150 are the converter systems mainly used.
