Environmentally Friendly Conditioning Technology for Defect-Free Slabs

A sustainable solution to facilitate the decarbonization of steel plant operations involves the surface conditioning of semifinished products like slabs by grinders. Traditionally, this task was accomplished using manual or automated flame scarfers on carbon steel. However, in recent years, grinding has emerged as a viable alternative without direct CO2 emission. An additional benefit is the production of swarf instead of slag, which can be directly recycled in converters and electrical furnaces. At last, grinding facilitates further steel and CO2 savings of at least 25%, owing to the superior control over the thickness of material removed afforded by grinding machines.
