The investment in Danieli’s straightening lines will allow up to 15 percent energy consumption and full-line setup time savings at JSW Steel’s JSW Salem Works.
Mumbai, India-headquartered JSW Steel Ltd has ordered two complete straightening lines from Italian technology provider Danieli Group for the conditioning of rolled steel bars for JSW Salem Works.
As stated in the official press release, the new installation will consist of two fully-automated and high- productivity straightening lines which are capable of conditioning a wide range of diameters, reaching straightening speeds up to 120 m/min.
The high-efficiency Danieli solutions featuring advanced automation equipment and process control integrated into a user-friendly interface would pave the way for savings of up to 15 percent in energy consumption and full-line setup times at JSW Salem.
The new design of the straightening rollers and the wide, variable working-angle cover a large field of bar diameters and material yield tensile characteristic to be treated, in terms of size and straightening tolerances. A precise head and tail bar straightness is also assured.
A hydraulic protection system and adjustable straightening force on the lower roller prevent cracks on the rolls due to overloads generated by operator machine settings, or due to highly ovalised and off- shape incoming hot-rolled, forged or extruded bars. A mechanical action will be carried out on the whole circumference of bars to obtain excellent straightening, up to 0.5 mm/m for as-rolled steel (up to 0.1 mm/m for bright steel).
