To expand and modernise itself, Steel Authority of India Ltd. (SAIL) has rebuilt its first blast furnace ‘Parvati’ situated at SAIL’s Rourkela Steel Plant (RSP).
The furnace has been built as a state-of-the-art facility with an additional capacity from 1139 cubic meter to 1710 cubic metre.
as a result of which the annual production capacity of the furnace will go up from 0.438 MT per annum to 1.015 MT
This technologically advanced blast furnace has advanced features which include new skip system, closed loop cooling system with soft water, twin flat cast houses at 90 degree apart with cast house defuming system, new turbo blower for high top pressure, new hot blast system for higher blast temperature, new coal dust injection system, new gas cleaning plant and a new dust catcher.
Apart from boosting production these features, will help reduce the dependence on coal which will, in turn, improve the carbon footprint making the new furnace more environment friendly.
Started on 24th January 1959 and dedicated to the nation on 3rd February 1959 by the then President of India Dr. Rajendra Prasad, it has been taken down five times for relining and major repair before it was put down on 5th August 2013 for total rebuilding. The furnace was completely dismantled and a brand new furnace was installed on the same foundation with available space and resources.
The furnace in its modernised incarnation would surely go a long way in further strengthening the productivity and profitability of the Plant.
