Siemens is to equip several Chinese aluminium factories with medium and low voltage drives. The value of the order is in the low tens of millions of euros and commissioning will be completed in several stages between November 2018 and April 2019.
The objective is to safeguard productivity in the rolling mills with powerful, reliable drive systems.
Siemens received the order from SMS China, part of the SMS group, a worldwide plant constructor and machine manufacturer in the ferrous and non-ferrous metal industry. In the light of increasing demand for aluminium, the company has received the order to construct a number of aluminium rolling mills.
Siemens will supply the drive technology for cold rolling mills near Liaoyang in Liaoning Province in north-eastern China, and for a cold and hot rolling mill near the port of Yingkou, also in Liaoning.
The scope of delivery of the aluminium rolling mills includes the medium voltage drive system, comprising Sinamics SM150 frequency converters, the entire drive control system, cooling plant, engineering station, associated project management, hardware and software engineering, including the commissioning of individual plant sections and low voltage drive components.
In addition, a heavy plate and Steckel mill will be equipped with low voltage equipment. It is located near Rizhao, a city of over 1 million inhabitants in Shandong Province in eastern China. This plant will mainly use Sinamics S120 low voltage frequency converters.
In order to guarantee the agreed key performance indicators, the order includes multiple tests (uncoupled and coupled test runs, availability test, load optimisation, final test), which will be performed in the plant.
