New BOF Put Into Service at JSW Steel Works
10/08/2015 - India’s JSW Steel Ltd. has installed a new basic oxygen furnace (LD) at its Vijayanagar works in Toranagallu, Karnataka, according to the contractor on the project.
The contractor, Primetals Technologies, said the BOF (LD) is the first of four replacement units to be installed at the facility. The furnaces will be replaced one at a time through the spring of 2016.
Primetals is supplying the converter vessels, which include the trunnion rings and suspension systems; two new tilting drives; two sets of quick-change couplings for top-blowing lances; and a basic automation package.
All of the converters will be equipped with bottom-stirring systems and constructed from high- temperature, creep-resistant materials in order to limit heat-related deformations. The converters, each of which will have a tapping weight of 180 metric tons, will have a water-cooled cone cooling system and an air-cooled trunnion ring.
With the specially designed air-and-water cooling system, the new equipment will have a longer service and reduce maintenance requirements, Primetals said.
The converters also have a larger interior volume than the ones being replaced. The greater volume will reduce slopping, Primetals said.
Primetals is responsible for supervising the installation and commissioning. It will engineer the modifications required to the converter housings, it said.
