He told reporters in Kolkata that there was a possibility that this new method would be used in the new plants which the company proposed to set up. The company's only plant in Jamshedpur uses blast furnace technology.
Speaking about the synergy which Tata Steel would derive after the acquisition of Corus, Muthuraman said that in the first three years, the company would save around 130
The company was also in the process of preparing the vision document for the year 2015.
Asked whether steel prices would go up due to rise in input costs, Muthuraman said that barring some short term fluctuations, prices would remain stable in the long term.
