In December, 2016 UHT commissioned a CLU® converter with the capacity of 12 tonnes at Hira Power & Steel in Raipur, Chhattisgarh, India. The CLU converter will be used for refining HC FeMn to MC and LC FeMn to meet the increasing market demand for a superior product.
UHT’s scope of supply includes a complete converter package comprising vessels, trunnion ring, hydraulic converter drive (HCD), gas mixing station, Level 1 PLC and Level 2 real-time UTCAS® Process Control System as well as process design and engineering of auxiliaries.
The CLU process is cost-effective and ideal for MC and LC FeMn production due to the excellent temperature control without alloy dilution. Super-heated steam which is utilized as one of the process gases acts as coolant by controlling the temperature in the metal bath through the endothermic reaction that occurs when the steam is split into Oxygen and Hydrogen after injection. Thus, by balancing the temperature, the need for cooling material decreases and the Mn yield is enhanced.
UHT – Uvån Hagfors Teknologi AB is a Swedish engineering company and well established global supplier of metallurgical processes and Technologies to the iron, steel, stainless steel and ferroalloy industry. We concentrate our activities to AOD and CLU® converter refining and GRANSHOT® metal granulation.
