SMS Siemag wins contract for modernization of JSPL caster with largest slab cross section in India
SMS Siemag will modernize the slab caster at the Raigarh, Chhattisgarh, India, works of Jindal Steel & Power Limited.
The revamp is designed to expand JSPL’s line of quality steel grades and slab dimensions . To this end, JSPL will add to its portfolio high-tech pipe and tube grades (API), high-carbon steels and microalloyed peritectic grades. The current slab size of max. 2,600 mm width and max. 280 mm thickness will be increased to 3,000 mm width and 300 mm thickness. The plant is rated for an annual production of 1.3 million t of steel slabs. Commissioning is scheduled for the end of 2013.
As part of the modernization, SMS Siemag will supply a completely new strand guide system. The ladle turret will be retained. The existing hydraulic systems will be upgraded in line with the new requirements. The modernization, scope will also include SMS Siemag’s supply of the dummy bar system, new molds as well as a new run-out with new torch cutting equipment.
Also included in the supply scope will be the complete X-Pact electrical and automation package, including the control systems and process models.
The equipment of the caster comprises several ISC modules (Intelligent Slab Casting) which are decisive to the quality of the product and production. Among these are remote-adjustable narrow sides of the mold for width changes and taper adjustments during casting (online) and position-controlled segment adjustments for performing Dynamic Soft Reduction. The manufacture of slabs of high internal quality is thus guaranteed by the above in combination with the width-dependent air-mist secondary cooling and the Dynamic Solidification Control process model.
The Integrated Production Quality System IPQSslab safeguards the slab quality through the monitoring of all relevant measured data.
PT. Gunung orders electric arc furnace and ladle furnace
PT. Gunung, Indonesia, has placed an order with SMS Siemag, Germany, for the supply of an ARCCESS electric furnace and ladle furnace for the new steelmaking plant complex in Bekasi, Indonesian province of West Java.
The furnaces are rated for an annual production of 1.2 million t. The range of charge materials for the electric arc furnace includes scrap, HBI and hot metal. With its new equipment, PT. Gunung will produce high-quality steel and supply the slab caster also ordered from SMS Siemag with liquid steel.
SMS Siemag’s scope of supply includes the engineering, the mechanical and hydraulic equipment plus the X-Pact electrical and automation systems which will be commissioned according to the proven ‘’Plug & Work’’ concept.
Commissioning of the furnaces is scheduled for the middle of 2013.
Electric arc furnaces of the ARCCESS series are optimized for the highly efficient use of electrical and chemical energy. The electric arc furnace will be equipped with the latest generation of the patented SIS (SMS Injection Systerm) oxygen injection system, which combines innovative injection and burner technologies. This concept provides its worth through high productivity while keeping production costs low.
At the Bekasi works, PT. Gunung operates a long-product line for the production of sections and wire rods, as well as a flat-product line for the production of heavy plates and pipes. All major production lines were supplied by companies of the SMS group.
