end of July, when the entire mill line will be
finalized and completely tested. ‘Rough’
operation of the big Mannesmann mill line
is due to start in October 2008.
The rolling mill of the big Mannesmann
was built during 1917-1918 and is one of
the world’s oldest rolling mills with well-
maintained integral parts. Over the years the
line has been continuously modernized and
adjusted, with only some original equipment
still in operation (piercing mill, pilger mill,
hot cutting mill and incline furnace). During
its lifetime, the rolling mill has processed
around 6 million tons of steel.
Mr Jaroslav Sarovsky, CEO and director
of Valcovna Trub, explains the reasons
for investment, “The main asset, besides
increasing the total capacity of the plant,
is improvement of surface quality and
accuracy of pipes, extending the assortment
of steel grades and length of pipes. Volume
of the non-destructive metrology will be
increased as well as possibilities of its
usage.”

Back in 2005, the company purchased
new technology from SMS Meer GmbH
with the aim of upgrading its facilities. The
team assembled to carry out the project
for Valcovna Trub consists of Trinecky
Inzenyrink, BKB Metal as, D5 as, and
Enviform sro.
As part of the investment, the Ignis
furnace was relocated in the 2nd quarter
of 2007. This was followed by the
development of the machining centre
with metallurgical tools, and building and
adjustment of braced areas in the
mill line zone. In October 2007,
work began on the ‘heart’ of the
whole project – the construction
of the rotary hearth furnace and
walking beam furnace.
Further developments have taken
place this year on installation of
other technologies. During May and
June, the final stages were due to
be carried out, including installation
of a cutoff for the mill line. The
finishing mills will be installed at the
Valcovna Trub TZ, one of the largest Czech
producers of thick-walled seamless steel
tube and pipe, is reaching completion of
an extensive multi-million dollar investment
programme.
Owned by Trinecke Zelezarny, the company
is currently in the stages of reconstructing
and modernizing its whole plant. At the
heart of this plant is a big Mannesmann
production line that produces seamless
steel tube and pipe with a diameter from
168mm to 406mm.
