The new continuous slab caster No. 4 from Siemens Metals Technologies entered service in August at the Toranagallu steelworks operated by Indian steel producer Jindal South West Steel Ltd. (JSW Steel). The single-strand caster installed in Steelworks No. 1 has an annual production capacity of 1.4 million metric tons of slabs, thereby increasing the total casting capacity of Steelworks No. 1 to 4.2 million metric tons. Like continuous slab caster No. 3, also supplied by Siemens, the new caster is equipped with the DynaGap Soft Reduction system. The resulting high internal quality of the slabs is the basis for producing high-quality steel tubes up to X65 in accordance with the API (American Petroleum Institute) standard, as well as other micro-alloyed steels.
At Steelworks No. 1 in Toranagallu in the Indian state of Karnataka, JSW Steel now operates four continuous slab casters. Casters No. 1 and No. 2 have been in operation since 1999 and were modernized by Siemens a few years ago. Caster No. 3 has been in operation since late 2006 and was the first plant in India in 2009 to be equipped by Siemens with DynaGap Soft Reduction technology.
The new caster No. 4 is part of an ongoing expansion program at JSW Steel. With a machine radius of eight meters, it has a metallurgical length of 35 meters. Presently, slabs are cast with a thickness of 220 mm and widths ranging from 800 to 1,600 mm. The machine has a design range for future slab thicknesses of up to 260 mm. The maximum casting speed is two meters per minute. Thanks to DynaGap Soft Reduction, slabs can be cast from high-grade steel tube grades such as X65 according to the API (American Petroleum Institute) standard, as well as other micro-alloyed steels.
