Boosting efficiency in the aluminium industry with digital twins

Contributed by:

The aluminium industry faces unique challenges, with equipment breakdowns causing financial losses and significant downtime. Traditional maintenance approaches, such as corrective and preventive maintenance, have limitations in efficiency and reducing downtime. The advent of digital twins technology and predictive maintenance strategies presents a game-changing solution for the sector.

The aluminium industry has already seen major changes driven by digitalisation and Industry 4.0 principles. The integration of IoT, big data analytics, blockchain, AI, and emerging technologies all play a crucial role in the growth of digital twins and predictive maintenance in aluminium manufacturing.

The aluminium industry stands to see large benefits from the widespread implementation of digital twin technology. By driving adoption at scale, aluminium businesses can achieve better performance, increased efficiency, risk mitigation, and cost reduction. In light of rapid technological advancements in this field, it is evident that digital twin technology holds immense potential and will continue to gain traction in the aluminium sector.

Digital Twins: A transformative technology

Digital Twins technology creates a virtual replica of physical equipment, processes, or systems. This means creating a digital twin of crucial components such as smelting furnaces, conveyor systems, and other machinery in the aluminium industry.

This digital replica is paired with IoT (Internet of Things) sensors and physical records containing design specifications to mimic the behaviours of the physical world. This lets it continuously collect real-time data from the actual equipment, providing a comprehensive view of its performance.

With the vast computing power available through cloud infrastructure, digital twins, aided by statistical models, can run multiple simulations in real-time to generate insights and recommendations for floor employees. Using digital twins in maintenance offers several advantages:

  • Improved real-time data interaction
  • Easy access to information
  • Support for collaboration and multi-user communication
  • Informed decision-making
  • Increased operational efficiency
  • Regular monitoring of equipment
  • Problem detection and resolution planning
  • Reduced downtime and unplanned downtime
  • Visualisation and simulation of complex scenarios
  • Measurement of the impact of future changes
  • Savings on maintenance time and costs

The many uses of digital twins

1. Predictive maintenance

Predictive maintenance aims to address the limitations of traditional maintenance methods by leveraging data and analytics to anticipate equipment failures before they occur. In the context of the aluminium industry, where precision and efficiency are paramount, the ability to predict and prevent failures is crucial. However, acquiring real-world data for training predictive maintenance algorithms can be challenging, leading to the synergy with Digital Twins.

Digital twin technology enables predictive maintenance by continuous condition monitoring, fault diagnosis, residual life prediction, and maintenance decision-making. This proactive approach allows for early detection of potential defects, empowering personnel to make informed decisions. The focus is on intervening before equipment failure, minimising unplanned downtime, and optimising efficiency.

2. Quality control

Reworked and defective pieces pose common challenges in aluminium manufacturing. A digital twin can generate insights and recommendations for process parameter settings to ensure product quality. By leveraging machine learning algorithms, manufacturers can adhere to quality standards and produce aluminium products with ultra-precise specifications.

3. Sustainability

The energy-intensive nature of aluminium manufacturing makes sustainability a top priority. Digital twins can run scenarios to determine optimum process parameters, providing recommendations for energy-efficient processes, resource optimisation, and waste reduction.

4. Supply chain optimisation

Digital twin technology extends its footprint to the aluminium industry’s supply chain, facilitating logistic optimisation and inventory management. By creating a virtual model of the supply chain and analysing data using statistical models, manufacturers can enforce best practices, optimising supply chains.

Digital twins in aluminium manufacturing – EGA case study

Emirates Global Aluminium’s (EGA) Al Taweelah alumina refinery provides a practical example of the application of digital twin technology in the aluminium industry. The Operator Training Simulator (OTS) serves as a digital twin, offering a virtual plant replica. The OTS, incorporating thermodynamic process models and mirroring the distributed control system (DCS), played a crucial role in identifying design gaps and potential issues during commissioning and start-up, ensuring a smooth ramp-up of aluminium production.

The future

As more businesses like EGA move towards predictive maintenance models, the mining industry stands to gain significantly from the widespread implementation of digital twin technology. Given the rapid pace of technological advancements, it is evident that digital twin technology holds immense potential and will continue to gain traction in the mining sector.

The synergies between digital twins, predictive maintenance, and broader Industry 4.0 principles further position the aluminium sector for continued innovation, efficiency, and sustainability. The industry can leverage digital twins to drive efficiencies in cost, quality, and time, thereby boosting overall performance and productivity. In conclusion, the aluminium industry’s recent embrace of digital twin technology and predictive maintenance represents a transformative shift in how aluminium manufacturing is approached.
