Mill improvements

India’s state-run Power Grid Corporation has awarded a contract to Alstom for an ultra-high voltage direct current transmission link between Haryana and Chhattisgarh. This new 3,000MW transmission link will run parallel to the first UHVDC transmission link, built by Alstom in 2012, to increase the total transmission capacity of the system to 6,000MW. The link will transfer power from the Chhattisgarh region to the load center in the northern region of the country, Alstom said. The contract will include converter terminal stations, converter transformers, gas-insulated switchgear, substation equipment, and communication and supervisory control and data acquisition systems (SCADA), and all equipment will be manufactured by Alstom’s facilities in India, United Kingdom, France and Italy. Elsewhere in India, Alstom has supplied HVDC systems for Vizag (Andhra Pradesh), Chandrapur (Maharashtra) and Sasaram (Bihar).

Over the past four years, ArcelorMittal has invested around $267 million at its site in Duisburg, Germany, of which $180 million was spent on a new wire rod mill. The rod mill can process high strength and ultra high strength steels, using the latest technologies to enable thermo-mechanical rolling processes. A new factory laboratory has also been installed alongside the rod mill, for quality control. the changeover to a symmetrical format for a continuous casting line. The new format will produce high quality steel ingots suitable for automotive forgings, such as gearbox parts and crankshafts that create less vibration and therefore reduce noise emissions. ArcelorMittal’s Duisburg site supplies semi-products for forging, as well as high strength and ultra-high strength wire rods for the automotive industry and renewable energy applications, for fastening elements and machine building.
