JSW Steel informed BSE that it has commenced production from the new 5 million tonnes per annum hot strip mill facility at Dolvi Works in Maharashtra. Dolvi Works has existing capacity of 5 million tonnes per annum & JSW Steel is in process to double its capacity to 10 million tonnes per annum with an investment of about NR 15,000 crore.

JSW Steel had awarded the contract to supply two continuous slab casters and Hot Rolling Mill in December 2017. The hot rolling line consists of one roughing stand with edger, a crop shear, a seven-stand finishing mill, three down coilers and a pallet conveyor. It produces hot strip with thicknesses from 1.5 to 16 millimeters and widths from 900 to 1,650 millimeters. The maximum coil weight is 34 metric tons. The mill can handle many different steel grades, including carbon structural steel, high quality carbon steel, low alloy steel, DP & TRIP, as well as HSLA and API grades up to X-70. Four stands of the finishing mill are equipped with pair cross technology. Pair cross rolls consist of upper and lower work and backup rolls set at an angle to each other, so that each pair forms an X when viewed from above. This enables the roll gap to be set optimally for fine control of the profile of the rolling stock. Depending on the angle set, the crown of the strip can be varied within wider limits as would be possible with conventional four-high stands with work roll bending. In addition, Primetals Technologies was to supply the complete basic (level 1) and process (level 2) automation system, as well as all drives and motors for the rolling line.
