ROLLING MILLS | Russula Newsletter No. 19 | November 2019
Celsa Atlantic chose Russula to upgrade
bar mill
Celsa Atlantic chose Russula to perform a mechanical
upgrade that allows the plant to roll 180 mm
size billets on both the bar and wire rod mills. The
objective of the upgrade was to achieve greater
flexibility and a higher tonnage output per billet. Included
within the mechanical scope of supply were
two roughing mill RCS stands, by-pass roller tables,
pinch rolls, toggle shear and looper.
The two RCS stands were installed after the reheat
furnace of the bar mill along with a bypass roller
table to replace the stands when they are not required
by the production schedule. High rigidity,
simplicity and reliability are the features of Russula’s
housingless mill stands. Once a stand is installed,
the only connection required is the air-oil connection;
operations and maintenance procedures have
been simplified to the fullest.
Russula is supplying an interconnecting trough to
connect the two mills. The trough is movable and is
designed to reduce the switching time. Two guiding
pinch rolls, a horizontal looper table, toggle shear,
electrical and pneumatic systems are all included
within the trough scope of supply. The ability to roll
180 mm square billets on both mills provides Celsa
Atlantic not only with higher flexibility but also cost
savings.
The equipment was installed during planned shutdowns
in September and October, 2018. The commissioning
occurred as scheduled on November
18, 2018.
As Russula celebrated its 30th anniversary this year,
it is time to reflect on how it all began. Twenty-nine
years ago, Celsa was Russula’s very first customer,
a long-lasting partnership that has spanned many
projects and many countries. With gratitude and
appreciation, Russula would like to thank Celsa for
their continued trust and confidence to undertake
this mechanical revamp.
