Plant types

  • Electric arc furnaces

    Technological leadership – powerful results

    Main data

    More than 100 years of the development, construction, and commissioning of electric arc furnaces give SMS group a valuable store of experience. With almost 1,400 electric arc furnaces in new construction and revamp projects, SMS group ranks among the world’s leading suppliers of electric arc furnace technology.

  • SHARC – Shaft arc furnace

    The cost-effective melting unit

    The SHARC (Shaft arc furnace) has two preheating shafts for drying and preheating scrap. Conventional scrap preheating systems use asymmetrical scrap loaders. With the SHARC, the entire furnace cross-section over the height of the two shafts is available for energy transfer. This is made possible by the symmetrical shape of the furnace. Also integrated is the DC high-current technology and the longer retention of the hot exhaust gases. Here, scrap can be melted homogeneously.

    The SHARC oven with scrap preheating is highly productive, efficient, and environmentally friendly.
