  • 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.

  • Located in Texas, Gerdau Midlothian ordered a new loop former table for its mill which produces reinforcing bar #3 up to #11, and plain rounds 5/8” up to 3 1/4”.  Russula supplied the engineering, mechanical equipment, installation supervision and commissioning support. The new looper was installed between stands # 16 and # 17 in the finishing end of the 340,000 tpy bar mill. 

    The purpose of the mechanical upgrade was to replace a looper table that was installed when the mill was originally built in 1975 with a new, modern uplooper. Since the existing looper table was larger than contemporary designs and lacked critical features, Russula provided a customized design uplooper with a rollerized trough, base and adjustable exit guide to fill in the space between the stands.

    Keep the oil in and the water out

    Many mills today roll with suboptimal loop formations because they are unable to quickly and easily adjust the height of the eccentric and persuader rolls. The combination of heat, scale, water, and oxidation formation often cause the common screw adjustment of the hold-down rolls to seize and the only way to change the position is to attempt to clean the screw, or simply replace it. Conventional persuader stops typically are adjusted by a bolt and lock nut which have a similar problem in becoming frozen in place by contamination and can happen as early as weeks after the installation. 

    Considering Gerdau Midlothian rolls a wide range of sections from 13-38mm, easy adjustment of the looper roll positions was an essential requirement in the design of the uplooper. Russula eliminated the seizing issues caused from exposure to the steel rolling environment by designing a fully sealed eccentric shaft assembly for reliable and simple floor and hold-down roll adjustments. In addition, the persuader arm roll assembly utilizes common components with the eccentric assemblies while the roll height adjustment is performed effortlessly with a newly designed, fully sealed, adjustable persuader travel stop assembly.

    Change out the cartridge assembly in minutes

    The eccentric roll assemblies can be changed out in a matter of minutes. Undo six bolts, replace with a spare cartridge and the mill can return to production immediately. The positioning of the eccentric rolls is adjusted from the operator’s side of the uplooper. Seven numbered positions provide visual clues of the roll positions and the operators can easily recognize a change in height adjustment, eliminating a source of human error that can happen if the roll setup is adjusted incorrectly between shifts and product size changes.

    Interchangeable spare parts

    The assemblies of the persuader arm and eccentric rolls are identical. Internal components such as bearings, seals and shafts are the same, reducing the quantity of spare parts that maintenance needs to keep in stock. Interchangeable parts reduce spare parts stock without having to compromise asset availability.

    Tension free rolling

    The actual value of the loop height is measured by a photoelectric scanner near the apex of the loop height, which falls between a range of 150-200 mm.  This value is compared with a set-point and the difference is used to correct the speed of the upstream stand in relation to the downstream stand to achieve the desired loop height for tension free rolling. 

    Successfully operating since January 2018

    The new uplooper was successfully commissioned in January, 2018 by the Gerdau Midlothian and Russula team. The uplooper was designed taking into consideration future replacement of the other two loop former tables which were installed when the Midlothian mill was built.  This new uplooper will be interchangeable with the future ones providing Gerdau greater flexibility and spare parts optimization.

  • Nucor Steel Marion has awarded Russula two separate purchase orders. In April 2017, the first order was received for the complete bar mill automation and electrics supply.

    Russula is scheduled to deliver the bar mill electrical and control equipment this summer and the water treatment plant electrical and mechanical equipment in October of 2018. The start-up of the modernized mill is expected to take place at the end of this year.

    Russula & Nucor

    In the last year, Russula has successfully completed five automation projects of similar size for other Nucor plants in Kankakee, Darlington, Kingman, Utah and Nebraska. This order marks the tenth water treatment plant sold by Russula in the past five years, three of which are currently in operation in the United States.

  • Russula was contracted to deliver the complete automation and drive system upgrade for Nucor Steel Utah’s bar mill #2, located in Plymouth, Utah, the third and last phase of a multiphase upgrade project. The objective of the multi-phase upgrade was to update obsolete automation and drive systems.

    Phase 3: Rolling mill #2 upgrade 

    Phase 3 included the upgrade of the mill entry area, 18 stands, 3 shears,  cooling bed and the interface with the existing reheat furnace. Whenever possible existing drives and control systems were reused and integrated into the new rolling mill control system.

    The mill started up in March 2018 after a comprehensive automation and drives upgrade 

    What sets Russula apart

    One aspect that sets Russula apart from other suppliers is that the commissioning team is formed by the same engineers who do the design, programming and Factory Acceptance Test of the project. This provides continuity and fluid communication throughout the entire project. Since the startup team is involved in all stages of the project, the customer knows who to call at all times and receives immediate feedback.

    Startup March 2018

    Nucor Steel Utah’s bar mill number 2 was successfully commissioned and entered into production during the second week of March, 2018.  The Russula commissioning team remained on-site after the startup to ensure the mill quickly returned to normal operations. 

  • The finishing block upgrade, Phase 3 of the multi-phase upgrade was successfully completed at the end of last year. The multi-phase revamp approach permitted Evraz (Rocky Mountain Steel), located in Pueblo, CO, USA to upgrade obsolete control equipment at the plant’s convenience and minimize mill downtime to reduce the impact on production. The upgrade of the mill, rod mill outlet and finishing block occurred over the course of two years.
