Rashtriya Ispat Nigam Ltd (RINL), the corporate entity of Visakhapatnam Steel Plant (VSP), marked a significant milestone with the inauguration of nitrogen pressure reducing stations. These stations are poised to play a pivotal role in enhancing the productivity of blast furnaces while concurrently reducing the production costs. The key strategy involves injecting pulverised coal at a higher rate into the blast furnaces. This innovative approach allows for the substitution of high-cost coke with more economically viable coal, resulting in a notable reduction in production expenses.

RINL’s proactive approach and concerted efforts have already shown promising results. The company has successfully increased its Pulverised Coal Injection (PCI) rate from the existing 100 kg per ton of hot metal to an impressive 180 kg per ton of hot metal in blast furnaces 1, 2, and 3 at VSP. This enhancement not only demonstrates RINL’s commitment to innovation but also reflects its determination to improve operational efficiency and reduce costs.

A K Bagchi, the director (Projects) and additional charge director (Operations) at RINL, played a pivotal role in inaugurating the nitrogen pressure reducing stations. He emphasised the significance of these stations in reducing the production costs of hot metal and boosting the productivity of blast furnaces at RINL. Mr. Bagchi underscored the urgent need to reduce production costs and hailed the collective efforts of RINL towards achieving a swift turnaround.

The inauguration of the nitrogen pressure reducing stations is a testament to RINL’s commitment to sustainable and cost-effective practices. By leveraging innovative solutions and embracing change, RINL is not only enhancing its own operational efficiency but is also setting new benchmarks for the steel industry. This strategic move is expected to not only benefit RINL but also contribute significantly to the overall competitiveness and sustainability of the Indian steel sector.
