Siemens to Upgrade Duisburg-Bruckhausen Hot Mill for ThyssenKrupp

09/20/2011 - Siemens VAI Metals Technologies has been commissioned by ThyssenKrupp Steel Europe AG to upgrade the entire strip cooling system in its hot strip mill 1 at Duisburg-Bruckhausen in Germany.

Siemens VAI Metals Technologies has been commissioned by ThyssenKrupp Steel Europe AG to upgrade the entire strip cooling system in its hot strip mill 1 at Duisburg-Bruckhausen in Germany. This involves the installation of a rough strip cooling system, an intensive “Power Cooling” section, and a new laminar cooling unit.
 
The value of the order is more than 10 million euros. The project is due for completion by the end of 2013.
 
The Siemens strip cooling system for the hot strip mill in Duisburg-Bruckhausen comprises a rough strip cooling unit and a finished strip cooling unit, which consists of one intensive and one laminar cooling section. The rough strip cooling is installed behind the Z3 roughing stand in the area of the intermediate roller table, which is said to ensure an even temperature over the entire length and width of the rough strip before it enters the finishing train. It also reportedly enables an increase in the throughput of the entire rolling mill train.
 
At the exit of the finishing train, an intensive “Power Cooling” section is installed. A similar system has already been in operation in the hot strip mill 2 at ThyssenKrupp Steel Europe in Duisburg-Beeckerwerth since December 2010. To reduce the temperature to a specific level, the flow rates of the adjustable-height spray headers can be regulated separately. A newly installed tank supplies the spray booms with water. At particularly high cooling rates, high-performance pumps can also be switched on.
 
The laminar cooling section begins immediately after the intensive cooling and the two systems are usually operated together. The laminar cooling is designed for all varieties of steel, but particularly for multi-phase steels that require uninterrupted cooling. The spray booms are individually controlled and their flow rates regulated.
 
In addition to the mechanical and electrical equipment, Siemens also supplies the necessary fluid systems and the automation technology, including a universal temperature control.
