In February 2009, blast furnace No. 3, which had been installed in the Toranagallu steelworks of the Indian company JSW Steel Ltd. and had been equipped by Siemens VAI Metals Technologies, was commissioned successfully. With an internal volume of over 4,019 cubic meters and a nominal annual capacity of 2.8 million metric tons of iron, it is the largest blast furnace existing in India today. This increases the production capacity of JSW Steel at Vijayanagar works to around seven million metric tons of steel per year. A cyclone separator developed by Siemens VAI is being used for the first time to clean the top gas in Toranagallu. This solution makes it possible to flexibly control the efficiency of dedusting and, as a result, to maximize the recovery of dust containing iron and avoid an excessive concentration of zinc or other heavy elements in the recycled dust.
