A major portion of these orders pertain to the Kalinga Nagar project of Tata Steel in Orissa, it said. Tata Steel is setting up four new Coke Oven Batteries, each of 0.75 million tonne per annum (MTPA) capacity with by-product plant. The company said it is L&T's third project in the Coke Oven construction business which has very few players. L&T is already constructing a coke oven complex for Tata Steel's Jamshedpur works and another coke oven complex for Bhushan steel's Meramandali, Orissa works. It is also engaged in construction of a Blast Furnace, Sinter plant, Steel Melting Shop and other units of Tata Steel's 6 mtpa Kalinga Nagar project.
