ROGESA Roheisengesellschaft Saar mbH
ROGESA Roheisengesellschaft Saar produces up to 4.6 million tonnes of hot metal annually in Dillingen, exclusively for the two shareholding companies Saarstahl AG and AG der Dillinger Hüttenwerke (each holding 50 percent). Blast furnace slag and slag sand are further products from ROGESA. It operates two blast furnaces and so-called upstream production processes such as the sintering plant and coal grinding plant. Like ZKS, ROGESA is a company without employees of its own. The staff necessary for operating the plant is provided by Dillinger Hütte.
