Tata Steel orders 2 CDQ systems for Kalinganagar Plant

25 March 2019

Nippon Steel & Sumikin Engineering Co., Ltd. (NSENGI) is pleased to announce that it has received an order for two large-scale coke dry quenching (CDQ) systems from Tata Steel Ltd., India's largest private steel company, jointly with its subsidiary company Nippon Steel & Sumikin Engineering India Pvt. Ltd. (NSEI). The CDQ systems, each capable of processing 200 tons per hour, will be installed at Tata Steel's Kalinganagar steel plant as part of its phase 2 expansion plan.

CDQ systems

The CDQ systems ordered feature the same processing capacity as the No. 1 CDQ system completed by NSENGI in February 2017 for the phase 1 construction of the steel plant, and they are the largest in India. As CDQ systems become larger in scale, it becomes increasingly difficult to maintain uniform cooling performance and the same level of efficiency. NSENGI has made considerable efforts to develop CDQ systems with improved cooling efficiency and boasts an outstanding track record of delivering numerous large-scale CDQ systems around the world. To date, NSENGI has consistently executed its CDQ projects without any major disruptions or failures, including the No. 1 CDQ system mentioned above, and its systems operating around the world have demonstrated exceptional reliability. These past successes have been rated highly and led to the latest order from Tata Steel.

In 2011, NSENGI delivered CDQ systems (processing capacity: 135 t/h each) of a scale capable of processing the total amount of coke required with one system for Tata Steel's Jamshedpur Works. These were the first such systems ever adopted in India. Subsequent CDQ systems delivered in India have increasingly grown in scale to provide greater processing capacity, giving consideration to efficiency and economics. NSENGI has so far received orders for a total of 12 CDQ systems from major steel companies in India.
