Siemens VAI Metals Technologies received orders to modernize electric arc furnaces for both the Saudi Iron and Steel Company (Hadeed) and Outokumpu Oy, a Finnish steel producer. Both plants will be equipped with a new hydraulic system which will improve the efficiency, availability and productivity of the furnaces.
The orders are worth several million euros. The projects are scheduled to be finished in the fall of 2010 and by the end of 2011 respectively.
Modernization services from Siemens VAI increase the efficiency and productivity of electric arc furnaces.
Electric Arc Furnace No. 1 in Hadeed's steel works in Al-Jubail and Electric Arc Furnace No. 1. in Outokumpu's stainless steel works in Tornio will each be fitted with a new hydraulic system, lifting columns for the carbon electrodes and current-conducting electrode arms. An integrated automation solution based on Simatic S7 will also be installed in the Al-Jubail works. Siemens Al-Khobar, the Saudi subsidiary, will handle the migration of the current process control system. The modernized hydraulic system will shorten the melting times of the furnaces, increasing efficiency and productivity and reducing operating costs. Electric Arc Furnace No. 1 in the Outokumpo's Tornio works will also be equipped with a new gantry cover in order to bring it up to a similar technical level as Electric Arc Furnace No. 2, which had been previously supplied by Siemens VAI.
