Donawitz steelworks

maj 12, 2008

Trend's Austrian Partner RGK-Energietechnik has recently installed IQ3xcites at Voest Alpine Stahl’s Donawitz steelworks in Austria,  they control more than sixty heat exchange units on the blast furnace cooling circuits. These reclaim heat for use elsewhere on the site. As the furnace cooling cycle is critical to the ironmaking process the controls need to be both accurate and reliable.

The controllers are provided with heat meter readings via a M-Bus interface. They connected over a fibre-optic network and are managed from a pair of Trend ‘963’ supervisors.
