Indian steel producer JSW Steel has started up two continuous slab casters at its Dolvi plant in Maharashtra in October 2021. Together, the two two-strand casters have an initial annual capacity of around 4.5 million tonnes of slabs with future capacity potential for 6 million tonnes. A number of technology packages ensure that the slabs have high internal and surface quality. Primetals Technologies supplies also a hot rolling mill to the new Dolvi expansion plant. 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 and 260 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 installed 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 also supplied the complete basic level 1 and process automation level 2 systems. DynaGap Soft Reduction in combination with Dynacs 3D cooling model enables slabs to be cast from high-quality pipe grades and other micro-alloyed steels.JSW Steel already operates three continuous casting plants from Primetals Technologies at its steel works in Toranagallu, Karnataka.
