Concast supplies a minimill to
Vallourec & Sumitomo do Brasil
Vallourec & Sumitomo do Brasil, Brazil, has placed an order
with Concast, Switzerland, for the supply of a steelworks
plant and equipment for a secondary metallurgy centre, and
a continuous caster for the manufacture of seamless tubes.
The plant is scheduled to go into production in February
2011.
The company is a joint venture between Vallourec, France, and
Sumitomo Metal Industries, Japan. The new works is to be built
in Jeceaba, Brazil, and will comprise an electric steel plant with
ladle furnace, a vacuum degassing facility and a continuous
caster. The works will produce liquid steel with an annual
output of 1.1 million tonnes. The order for the seamless-tube
rolling mill went to SMS Meer, likewise a company within the
SMS group.
The ladle furnace, equipped with a transformer of 26 MVA
+ 10 per cent, will achieve a heating rate of approximately
5°C/min. The vacuum degassing facility is of twin-tank design
and is equipped with a mechanical pump. The emptying time
for the system is less than seven minutes, with support for a
rapid-casting cycle.
With five strands and a casting radius of around 12m, the
continuous caster produces round blooms in the diameters
270mm, 340mm and 406mm. The casting machine is
equipped with electro-mechanical tundish stoppers, electro-
magnetic stirrers, and a compact hydraulic mold oscillator.
In addition, there is a deburrer and an automatic marking
machine to which is linked a visual product recognition
system.
The Concast supply scope includes the complete supply
of mechanical and electrical equipment, together with the
automation (levels 1 and 2), supervision of erection and
commissioning and training.

stock, the company is usually able to finish production within one
to two weeks. Orders for lengths other than standard 6,000mm
are also welcome. For different steel grades, the company
would need a minimum order of around 3 tons (per dimension)
in order to start production (daily production is around
15-20 tons).
The company calculates prices according to the actual weight of
material delivered, rather than based on the measured thickness
of the products.
