Siemens Rolling Mill Equipment Will Increase Productivity and Improve Product Quality at Nikkei Siam Aluminium

Linz, Austria, (PresseBox) - Siemens Metals Technologies has been awarded an order by Nikkei Siam Aluminium Ltd., Thailand, to modernize the company's aluminum rolling mill by supplying new mechanical equipment, as well as process and drive systems. This is intended to both increase productivity and further improve product quality to cope with the growing demand of automotive related industries. The new equipment will more than double both the rolling speed and the coil weight. This project has a total value of some 5.5 million euros, and is scheduled to be completed by the beginning of 2009.

The new drive components will increase the rolling speed of the mill at Nikkei Siam Aluminium from 300 to 683 meters per minute. The coil holder mechanisms will also be modified. This will enable the plant to process coils weighing eight metric tons in future, instead of the previous maximum weight of 3.5 metric tons. This will, in turn, reduce the number of times the coil has to be changed and also allows faster roll change times increase the rolling mill's availability and production.

The scope of delivery also includes the following technological control systems to optimize the processes: An automatic gauge control system, an automatic flatness control system, and Siroll shapemeter rolls with integrated solenoid valve spray bars to ensure greater flatness and better surface quality.

This new equipment will be installed during a planned plant outage starting in October 2008, and it is scheduled to come into operation in November 2008. Siemens is also responsible for supervision of the installation and customer training. This project is being run from Siemens Christchurch location in Great Britain.

Nikkei Siam Aluminium is a wholly owned subsidiary company of Nippon Light Metal, Tokyo, and it is the leading aluminum producer in Thailand. The company employs some 280 people at its Pathumtani location near Bangkok. The plant has an annual production capacity of 20,000 metric tons of aluminum sheet and 7,000 metric tons of aluminum foil.
