Prevas Reduces Energy Consumption
in Finnish Steel Industry
Prevas has received an order from Finnish company Rautaruukki Oyj. Prevas' specialized expertise in furnace and energy control for the steel industry is a key factor for the project. The company improves the quality and efficiency in production and energy consumption through careful control of the slab temperature in the customer's furnaces. The order is worth SEK 4 million. The control system will be reviewed in connection with upgrade of the furnaces at Rautaruukki Oyj plate mill. Prevas received the order to replace the control system for slab furnaces with its in-house developed product, FOCS-RF, a market leading system for optimizing all aspects of heating of slabs for rolling. Heating steel slabs is an energy-intensive process. Efficient control of furnaces requires optimization of productivity, quality, and energy consumption. Prevas worked with industry organization Jernkontoret and Metallurgical Research Institute AB to develop the FOCS-RF software to carry out this optimization. Energy savings of 5-10 percent can usually be achieved at the same time that the production rate and quality are controlled for maximum yield. "We are extremely pleased with this order. It proves that our specialized expertise in furnaces controls and the investment in this product are the right strategy. Rising energy costs and increased global competition for customers that produce advanced steel products also support this initiative," says Christer Ramebäck, business area manager Prevas AB. “Prevas' product was chosen in competition with several other systems. Factors such as the product's many possibilities to find energy savings, increased quality control, proximity to support, and the ability to further develop functions even after startup were pivotal for the choice," says Esa Kantola, project manager for the furnace investments. A long-term, structured process with continual improvements of productivity and quality are paramount. Innovation in the form of new technological solutions is also essential. With operational experience in more than 1,000 industrial projects, Prevas has helped its customers to cut costs, improve quality, and build their brands.For additional information, contact
