The Steel Authority of India Limited has placed an order with Primetals Technologies for the design, supply, and installation of a new hot-blast stove for blast furnace No. 5, known as “Kalyani,” at the IISCO steel plant in Burnpur, Asansol city, West Bengal, India. This fourth hot-blast stove is a strategic addition to enhance operational reliability and allow for maintenance of existing stoves without disrupting production.
The new stove will feature an internal combustion chamber type design, incorporating advanced technologies such as a "mushroom dome" for extended equipment lifespan and a vertical ceramic burner for optimal mixing and efficient combustion. The project also includes the extension of the hot-blast main to integrate the new stove seamlessly.
Primetals Technologies will be responsible for the comprehensive design, engineering, manufacturing, and construction of the new stove shell. This includes the supply of high-grade refractories, expansion joints, hydraulic systems, and valves, along with the necessary support and access structures to accommodate the hot-blast main extension.
The implementation of the new hot-blast stove is scheduled to be completed within 17 months from the contract signing. Upon completion, the IISCO steel plant will benefit from the enhanced operational flexibility provided by the additional stove. This will allow for continuous production even when existing stoves are taken offline for repairs or maintenance.
The new stove will ensure the security of operations at the IISCO steel plant, which is crucial for maintaining high production efficiency and meeting the demands of SAIL's diverse customer base. The advanced combustion technology and robust design will contribute to the long-term sustainability and productivity of the steel plant.
