Indian steelmaker Jindal South West Steel Ltd. (JSW Steel) has recently issued the Final Acceptance Certificate (FAC) for the last of four LD (BOF) converters ordered from Primetals Technologies in September 2014, which had been started up in January. The shut-down lasted only 33 days, nine days less than contractually agreed. The other three converters commenced operation one by one, beginning in September 2015. The converters installed in the Steel Melt Shop no. 2 in Vijayanagar, Toranagallu are made of high-temperature creep-resistant steel.
On account of the high maintenance requirement of the existing LD converters in steel works no. 2, JSW Steel decided to replace them with new converters from Primetals Technologies. Each converter has a tapping weight of 180 metric tons. Primetals Technologies supplied the converter vessels, including the trunnion rings and suspension systems. The converters are constructed of high-temperature creep-resistant materials in order to limit heat-related deformations. The scope of delivery also included two new tilting drives, two sets new quick-change couplings for top blowing lances, and the complete basic automation (level 1) for the converters. Primetals Technologies also was responsible for supervising the installation and commissioning, and engineered the modifications required to the converter housings.
