New Delhi/Rourkela: Excelling once again, SAIL-Rourkela Steel Plant (RSP) has registered a new national record in Torpedo ladle life. The plant scripted this record by clocking life of 2,552 heats in Torpedo ladle #2 in a single campaign surpassing the earlier best Life of 2,407 heats achieved in November 2020. The Torpedo ladle #2 started its campaign on June 13, 2018 and after handling 7,62,207 tonnes of hot metal, it was ultimately putdown for debricking on April 24, 2021. The significant achievement was made possible because of the dedicated and coordinated efforts of Refractory Engineering (Services) and the Blast Furnace department.
Notably, such high life in torpedo ladles could only be possible with the adoption of innovative lining pattern and maintenance practices by the Refractory Engineering Department like metal heal practice, window repair concept, modifications in the heating cycle, online inspection and thermography etc. As on date, three mid repairs were carried out in the torpedo ladle in line with the scheduled maintenance plan.
The endeavour ensured both tangible as well as intangible benefits in terms of enhanced Torpedo Ladle availability, better logistics and reduced refractory consumption. The effort is one amongst many such initiatives being undertaken by the enterprising RSP collective to reduce the cost of production and further improve the techno-economic of the plant.
