To further reduce the carbon footprint, SMS group has introduced the ALLCHARGE technology .The ALLCHARGE design is based on the combination of flat bath operation with continuous charging of scrap coupled with a separate extraction line for the off-gases. Thus, ALLCHARGE de-couples the off-gas line from the scrap conveying line, minimizes carbon dioxide direct emissions and improves control on dangerous pollutants like NOx and VOC.
The pairing of flat bath continuous scrap melting together with direct rolling of rebar or very compact coils leads to a reduction of greenhouse gas emissions at the site by up to 70%. Liquid steel is produced and refined by an advanced steelmaking plant, based on the ALLCHARGE design coupled with a disruptive power feeding concept based on IGBT electronic modules named AURA. Since electrodes are made by graphite material, the reduction in consumption reflects immediately in a reduction of CO2 footprint. This enables the lowest environmental impact in terms of CO2 and NOx emissions, which is further enhanced by a potential connection to renewable energy sources. Use of modular concept and state-of-the-art electronics guarantees best efficiency and highest power density, with a minimal impact to the grid. Proprietary control algorithms and innovative modulation technologies ensure high power transfer and fast control.
The flexible CMT® process can be designed for a wide range of products, from straight rebars to Vertical Compact Coils up to 8 tons (VCC®). Integrated level 1 and level 2 automation systems, managing all production process aspects from the scrap yard logistics to the mill finishing area, as well as covering maintenance of the plant are also key elements for an efficient and cost-effective production.
The CMT® minimill also provides solution for compact and small property sizes. A smaller plant footprint thus minimizes the investment in foundation and construction materials usually needed for larger plants. Thus, the CMT® minimill not only reduces operating costs during ongoing production, but is also extremely efficient regarding the initial investment.
