EXSTREAM II: THE DANIELI QUENCH SYSTEM FOR QUALITY PLATES
me-metals: JSPL relies again on Danieli technology for Steckel mill improvement
According to me-metals cited from mining.com, The new, Danieli Direct Quench DQ system Exstream II ordered by JSPL for the Steckel mill in Raigarh, India, will significantly enhance the cooling system capabilities, extending the range of achievable cooling rates and different cooling strategies in plates production.
Exstream II is the new-generation cooling system that allows easy and flexible production of a wide range of added-value products like High-Strength Steels, of plates with different mechanical properties, and lowers OpEx by reducing the amount of alloy elements in the steelmaking process for final products with improved weldability.
The DQ section of Exsteam II system is able to operate in two modes: high-pressure mode with very high cooling capability, and low-pressure mode, functioning as a normal ACC module.
The nozzle pattern ensures a uniform and effective cooling process. The headers are arranged in zones with independent control by proportional valves, allowing for the creation of a thermal profile across the plate width and ensuring precise final plate temperatures.
This installation follows a major revamping project executed by Danieli several years ago, which included major upgrades to the four-high finishing stand, pinch-roll shears, and automation system, along with new Accelerated Cooling System (ACC), power downcoiler with coil handling system, and sampling station.
All equipment will be manufactured at Danieli India quality workshops in Chennai.
