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 rolling mill stands and accompanying equipment for the interconnection were manufactured and assembled in reputable workshops throughout Europe. Close proximity to the Russula headquarters allowed the engineers to perform frequent quality checks. Strict controls in the manufacturing process together with premium materials is why Russula rolling stands are built to last.
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.
