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.
