ARC awarded contract to widen the S5 aluminium cold rolling mill at HULAMIN in South Africa

Alan Richards • Feb 08, 2024

In September 2023, HULAMIN awarded the contract for the widening of their S5 aluminium cold rolling mill to A Richards Consulting Ltd (ARC). This followed one of several engineering studies carried out by ARC and resulted in the S5 widening project being awarded against a tight deadline to complete Phase 1 by December 2023 ready for board approval. This was immediately followed by Phase 2 which will see the widening project designed, manufactured and implemented by the second quarter of 2025.


Project key features:

  • Increase maximum strip width capability of the mill to 1875 mm
  • Higher material temperature capability from faster, back-to-back rolling
  • Improved strip quality including:
  • New flatness sensor incorporating load cells
  • New strip scanner heads
  • New spray system
  • New enhanced ARC strip dryness system
  • An upgraded optical centre guide system
  • A new, ARC designed compact 3-roll entry bridle with colouring roll
  • A new oil-air lubrication system for the mill
  • Upgraded spool handling to cater for dual spool lengths

 

Wider Strip Processing

Increasing the maximum strip width will open new markets to HULAMIN and allow the S5 mill to focus on processing wider, 14-out high quality can stock material. In addition, this will enable better distribution of product across all areas of the plant thereby increasing the overall plant utilisation. The main component of this upgrade being a new entry bridle with colouring roll designed and supplied by ARC, which not only allows the wider material to be processed but also includes features to ensure accurate roll positioning, stable tension control and ease of maintenance.

 

Also included are new, longer work rolls and back up rolls with new bearing arrangements and the associated chock modifications to accommodate the increased width and higher operating temperatures.

 

The ARC design caters for increased strip temperatures and speeds but also meets the challenges of accommodating the new surface inspection cameras, strip scanners, strip dryness equipment and flatness measurement system in an already congested area of the mill.

 

Mill Upgrades

Upgrading a rolling mill is often necessary when introducing a new product and provides an alternative to investing in completely new equipment. Upgrading is also a cost effective solution to updating old or obsolete technology and can also minimize the loss of production associated with replacing equipment with new. However, this is a very specific area of expertise and one which requires the highest level of know-how.

 

Such is the case with the HULAMIN upgrade, where ARC has designed the new and upgraded equipment and planned the implementation to minimize the loss of production and disruption to the plant. The ARC team has many years of experience in modernisations and upgrades of rolling mills and processing equipment for the steel, aluminium and other non-ferrous industries.

 

Working closely with HULAMIN over the past year or so, ARC has been able to provide insight into the process aspects of this upgrade and the analysis and evaluation of different solutions. ARC also provided CAPEX estimates for the design, supply and implementation and now the full design, supply and supervision of installation & commissioning of the new upgraded S5 cold mill.

A step into the (almost) unknown...

By Alan Richards • 31 Aug, 2019
Having spent 30 or so years (yes, hard to believe I know), working mainly in the corporate world for large capital equipment and plant builders in the metals and mining industry, and also having been made redundant 3 times in the last 4 years, twice just 12 months apart and once threatened with legal action just for trying to find a job for myself and a dozen colleagues, I decided enough was enough. Yes, I've enjoyed my time in the corporate world I suppose, especially during the periods where I've been lucky enough to live and work overseas and meet the most wonderful people along the way, but in my 'late fifties' it's time to rethink my objectives and redirect my energy into something slightly more varied and rewarding! Maybe it's just a symptom of growing older, maybe it's just me, but it doesn't get any easier does it? Having said that, I always need a challenge or a project and I'm certainly not one to shy away from hard work and putting in the hours, but it is really important for me to love what I do and get that sense of satisfaction whilst achieving tangible results, which is what I've been lacking in recent years. I understand there's not the job security there was in decades past, and also the competition has increased, but 'taking back control' is the way to go apparently! Anyway, spurred on by the annual redundancy and the dread of having to rely on the unpredictable world of metals engineering, I decided to join ibd Business Advice Group as a self employed but accredited business consultant, pick up some new skills through their extensive training courses, and put my energy into helping others starting out on their long road to retirement. Hopefully I can use the diverse and extensive knowledge and leadership, sales, management, manufacturing and project development experience I've gained living and working in countries such as India, South Africa, France, Italy, Russia, Korea and China and of course the UK. I will keep you updated on my progress through what I expect (and hope) to be a challenging but rewarding existence, at least in job satisfaction and work-life balance!
