SteelNews.com is a publication created by the Association for Iron and Steel Technology (AIST) for the steel community. We are the leading source for technological and innovative news on the people, producers and suppliers in the North American and international steel communities.

The Research and Development Centre for Iron & Steel (RCDI&S), a division of Indian state-owned steel producer Steel Authority of India Limited (SAIL), has developed technology which will result in energy cost savings of at least 10%, an official at SAIL said.

The technology has been adopted on a pilot basis at the hot strip mill at SAIL's Rourkela Steel Plant and is expected to result in energy savings of $3.5 million per year, the official said.

The technology will also be offered for adoption by private sector steel producers and, according to RDCI&S, if all Indian steel producers were to accept it, it could lead to national energy cost savings of $25-28 million per year.

The technology developed by RDCI&S scientists involves application of lubricants to the rolling surface during the hot rolling of steel coils, which reduces roll force and energy consumption by 10% and roll wear by 50%, the official said.

A hot rolling oil for the purpose has been jointly developed by RDCI&S and Indian Oil Corporation, the country's largest oil refiner and marketer.
