Primetals Technologies has won an order from JSW Steel Ltd an Indian steel producer, to supply two continuous slab casters to its Dolvi plant in Maharashtra. Together, the two two-strand casters will have an initial annual capacity of around 4.5 million tonnes of slabs with future capacity potential for 6 million tonnes. The casters are scheduled to come on stream in the middle of 2019. The order to supply a hot rolling mill to the Dolvi site has also been received by Primetals Technologies. The hot rolling mill has an annual capacity of 5 million tonnes per year.
The two continuous casting plants from Primetals Technologies are designed as bow caster with straight SmartMold, and have a machine radius of nine meters and a metallurgical length of 34.5 meters, with a provision of 36.9 meters in future. Slabs will be cast with a thickness of 220 millimeters in widths ranging from 900 to 1,650 millimeters. The maximum casting speed will be just under two meters per minute with a provision of 2.1 meters per minute in future. Primetals Technologies will install a number of technology packages to ensure not only a trouble-free casting process, but also slabs with high surface and internal quality. The packages include the Mold Expert breakout detection system, the LevCon mold level control, the DynaFlex mold oscillator, and the Quality Expert inline quality assurance system. Primetals Technologies will also supply the complete basic (level 1) and process automation (level 2) systems. DynaGap Soft Reduction in combination with Dynacs 3D cooling model will enable slabs to be cast from high-quality pipe grades and other micro- alloyed steels. Primetals Technologies will supervise installation and commissioning of the continuous casting plants, and train the customer''s personnel.
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. Primetals Technologies is responsible for the design, engineering and supply of the mechanical equipment. 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. Across the world, around 150 finishing stands are equipped with pair cross technology. -The 19th Guangzhou Die-casting, Foundry
