Primetals Technologies to supply equipment for relining a blast furnace for ROGESA

  • Blast furnace 4 to be equipped with 4 integrated automation solution
  • Redundantly designed control system for high availability


Primetals Technologies has received an order from ROGESA Roheisengesellschaft Saar mbH in Dillingen, Germany, to modernize the electrical, measuring, analytical and automation equipment in conjunction with the relining of blast furnace 4. The project involves equipping the blast furnace with a new control system based on Simatic PCS7, new automation and new switchgear. The existing field devices will be replaced, and the cabling renewed. Primetals Technologies is also responsible for hardware planning. The order is worth over ten million euros.


ROGESA Roheisengesellschaft Saar mbH, Dillingen, is a joint subsidiary of Dillinger Hüttenwerke Incorporated, Dillingen, and Saarstahl AG, Völklingen, each of which holds directly and indirectly 50 percent of the shares. ROGESA currently produces up to 4.6 million metric tons of hot metal per year, exclusively for the two shareholders. Blast furnace 4 was built in 1974, and last relined in 2003. With a hearth diameter of 11.2 meters, it has an effective volume of 2,360 cubic meters. The nominal production rate is 6,100 metric tons of pig iron per day.


In conjunction with the relining, blast furnace 4 will be equipped with a new control system based on the current version Simatic PCS7 V8.1. The system is completely virtualized, and equipped with a redundant OS server, to which are connected five engineering stations, 15 operator stations, six AS 410 automation systems and type ET200SP distributed I/O devices. Data is exchanged via Profibus and Profinet. An archiving and reporting system, a system for recording and analyzing measured values, and a network management solution are also integrated into the control system.


Primetals Technologies will also be responsible for planning the hardware and adapting it to the new structure, renewing the switchgear, ET stations and local control points, and installing the requisite network infrastructure. At field level, Primetals Technologies will replace all field devices and the complete measuring and analytical equipment, as well as renewing the cabling for the complete electrical, instrumentation and control equipment. Bähr Anlagentechnik will lead an external consortium that will install the electrical equipment.
