SAIL Turns to Primetals Technologies For IISCO Plant Expansion
03/04/2026 - The Steel Authority of India Ltd. (SAIL) has selected Primetals Technologies to supply a new pelletizing plant, three 165-metric-ton ladle furnaces and two 165-metric-ton RH degassers as part of its IISCO steel plant expansion in Burnpur.
The new pelletizing plant will use the 576-square-meter straight-grate concept with an estimated capacity of 4.2 million metric tons annually. Primetals Technologies will provide a digitalization solution including smart sensors and predictive control modes.
Primetals Technologies said it will supply the equipment including the induration area, pelletizing discs, motors and drives. Its Austrian office will handle design, engineering and delivery of components. The Indian affiliate will provide local engineering services, equipment supplies and project coordination. Lloyds Engineering will provide equipment for iron ore grinding, filtration and flux grinding.
The secondary metallurgy equipment will allow for better control of chemical compositions and temperature along with being used to heat liquid steel. The Legelshurst office will design and provide basic engineering for the RH degasser plants along with supplying components. Primetals Technologies India will provide engineering and remaining supply for the RH degassers. It will also provide all the basic engineering, detail engineering and supply for the ladle furnaces and project coordination, the companies said.
The RH degassers will have two single RH stations with a steam vacuum pump system, ferroalloy and microalloy addition systems. It will feature monoblock RH vessels and Primetals Technologies’ vessel and ladle lifting system, combined oxygen blowing lance system and a level 2 RH optimization system.
The ladle furnaces will have two offline and one online furnace featuring transfer cars, ferroalloy and flux addition system, secondary emission control system, wire feeding and electrode nippling stations. Other features include a 3-point hydraulic roof lifting system, bottom stirring, top stirring lance, arc heating system with a HT transformer, circuit breaker, electrode regulation system and a level 2 LF process optimization system.
SAIL said the greenfield project will boost its steel capacity and allow IISCO to produce hot rolled coil and API-grade steel for the oil and gas industries. It is the first time SAIL will build its own pelletizing plant instead of using build-to-operate models. Commissioning is scheduled for 2029.
