Valmet will supply an information management system to SSAB's steel mill in Raahe, Finland, to manage iron production and raw materials. The system will be integrated with the mill's Valmet DNA automation system and replace an existing production management system.
The order is included in Valmet's third quarter of 2018 orders received. The system will be taken into production use in spring 2020.
"Valmet will provide us with a comprehensive production management level solution, including hardware and software. The flexible delivery model has taken into account future system development needs, and upkeep services will ensure a long system life cycle," says Marko Tilja, Project Manager at SSAB's Raahe mill.
"In recent times, we have increasingly invested in developing our production management solutions. This order is very significant for us, as it shows our capability to supply not only distributed control systems, but also production management solutions. The entire sales process was carried out with excellent cooperation between SSAB's and Valmet's key people, giving a good starting point for the delivery," states Jani Hautaluoma, Director, Process Automation, Valmet.
Cooperation between the Raahe mill and Valmet started back in 1986 when Valmet delivered a Damatic Classic system for the customer's coking plant. It has been followed by many other system deliveries for various processes at the steel mill.
Information about Valmet's delivery
Valmet's delivery includes a Valmet DNA information management system for iron production and a Valmet DNA Integrated Operations data collection application for reporting, data collection, recipe calculation, production planning and raw material management. Through the integration of modern user interfaces and reports, the mill will be able to improve production optimization and raw material management.
"Flexible reporting tools and upgraded user interfaces ensure that both production management and raw material management can be developed in the future. Valmet's local support ensures reliable system upkeep. And we plan to continue strengthening our delivery and support organization further," adds Hautaluoma.

Valmet will supply a boiler plant to Raahen Voima, located in Raahe, Finland. The value of the order is around EUR 30 million. The order is included in Valmet's second quarter 2014 orders received.
Valmet's delivery is part of Raahen Voima's EUR 121 million investment to renew the power plant at the Raahe steel works.
The boiler plant with a steam capacity of 141 megawatts (MW) will be built adjacent to Ruukki's Raahe steel works and will partially replace an existing power plant. The new plant will use blast furnace gas and coke gas from the steel works as its fuel. Continuous incineration is required in order to secure uninterrupted steel production. Secondary fuels used in the new plant will be propane or natural gas and light fuel oil.
The boiler plant is designed to meet the lowest possible environmental impacts, and the technology meets the limits set out in the EU's new Industrial Emissions Directive. Special attention is also paid to the fuel flexibility required by the process changes of the steel works.
"The renewal of the old power plan has been under planning for a long time, and as the old equipment is coming to the end of its operating life, it is necessary to renew the equipment. By building a new power plant we can increase the energy and cost efficiency of the whole plant. Valmet is a trusted Finnish partner for us, and is a known supplier of boiler plant technology," comments Pekka Inkala, CEO of Raahen Voima.
Raahen Voima in brief
Raahen Voima is a joint venture recently established by Ruukki Metals Oy and EPV Energia Oy with the purpose of providing Raahe's steel works with electricity and steam. Ruukki owns 75% of the new company and EPV Energia 25%. www.ruukki.com, www.epv.fi.
Valmet will supply a heat recovery steam generator to LKAB's Svappavaara mining area in northern Sweden. The value of the order is nearly EUR 10 million. The order is included in Valmet's first quarter 2014 orders received.
Valmet's EPC (engineering, procurement and construction) delivery will cover the heat recovery system including all the process equipment, such as water treatment, feed water system, heat exchangers, pumps and instruments as well as installation and commissioning. The equipment will be delivered in September 2014, and the mechanical installation will be ready in March 2015.
The main task of the heat recovery steam generator is to cool down the process gases from Svappavaara's iron ore pelletizing plant. The cooling is necessary for the flue gas cleaning downstream to operate. For this reason high reliability and availability provided by Valmet's technology are particularly important for successful ore processing. The recovered heat is utilized in the local district heating network. The heat recovery steam generator gives also LKAB the possibility to install a steam turbine for electricity production in the future.
"LKAB has shown confidence in our capabilities to meet their demands by awarding the contract to Valmet. We delivered a similar boiler to LKAB in Kiruna in 2008," says Mikael Barkar, Director, Sales, Pulp and Energy business line, Valmet.
The heat recovery steam generator at Svappavaara will cool the process gases from the iron ore pelletizing plant from 320-400 degrees Celcius down to 140 degrees Celcius, which is the temperature needed at the flue gas cleaning plant downstream.
The boiler will generate 28 megawatts (MW) of steam at two pressure levels, approximately at 2.5 and 15 bar. The steam is condensed in a hot water condenser, and the heat is utilized in district heating. Alternatively the heat can be used in the industrial water network. All critical systems are redundant to ensure the high availability.
Ore processing in Svappavaara takes place in the form of concentration and pellets production. Luossavaara-Kiirunavaara AB (LKAB) is a high-tech international minerals group, a world-leading producer of processed iron ore products for steelmaking, and a growing supplier of mineral products for other industrial sectors. It is owned by the Swedish government. More information on LKAB at www.lkab.com.
