Developed by Danieli, the Exstream II system consists of medium-pressure water headers, dynamically controlled by a cooling model developed by Danieli Automation. The system optimizes the cooling process of steel products, thereby enhancing metallurgical properties, reducing the use of alloys, and improving energy efficiency.
Thanks to Exstream II technology, it will be possible to produce steel with superior mechanical properties and finer microstructure. In addition, since it eliminates the need for off-line thermal treatments that require re-heating after rolling, significant energy savings will be achieved. This also means a more sustainable production process with reduced use of additives.
The new system is scheduled to be fully operational by the end of 2026. With the integration of Exstream II, SAIL aims to both expand its product range and improve operational efficiency.
Previously, Danieli had already delivered various upgrade packages to the same plate mill, including L1 and L2 automation systems, mechanical retrofitting, and a new side trimming shear.
Meanwhile, another Exstream II system is also being installed at JSPL’s Steckel mill in Raigarh, India, and is expected to be commissioned in the last quarter of 2025.
