During the 'Chintan Shivir' organized by the Ministry of Steel, Ved Prakash, the Executive Director of Digital Transformation at the Steel Authority of India Limited (SAIL), revealed the industry’s digital future. Prakash shared that advanced technologies like AI and ML are changing processes across the steel sector. Following are the key insights from his address.
At a time of radical technological integration, the integration of technologies such as Artificial Intelligence (AI), Machine Learning (ML), and digitalization into the steel industry is seeking to revolutionize the operational processes, optimize efficiency, and improve environmental responsibility. The sector is on the cusp of bringing in new digital transformation capabilities that will enable faster project execution, asset optimization, and improved sustainability.
AI and ML in Steel Manufacturing and Mining
Machine Learning and Artificial Intelligence have saturated a lot of sectors like finance, healthcare, and agriculture, etc. These technologies are being employed in the steel industry, helping to refine processes, make real-time adjustments, and bring in data-driven decision-making. Using AI, the steel industry can effectively monitor and control physical processes by creating a dual network structure, one for IT (supporting areas like HR and finance) and one for OT (Operational Technology).
The use of AI and ML is particularly of value in steel and mining operations. Advanced data analytics can be applied to anything from logistics and raw material handling to production optimization. Virtual replicas of physical processes, called digital twins, are playing an increasingly important role in predicting and tuning production in such a way that operators can see problems coming and adjust accordingly.
The Three Pillars of Digital Transformation
Three foundational pillars support the journey to a fully digitized steel manufacturing ecosystem. Digitization is the first pillar and it deals with converting the entire physical documents, the process diagrams, and the manuals to digital forms. This is an important step because it makes a complete data repository that makes it easy to access information and sets the footing for making informed, data-driven decisions.
The second pillar, Digitalization, is the integration of AI and ML into processes across the whole value chain, from mining to production. Embedding predictive models into operations allows companies to predict what can happen at different points in the process such as material blending, furnace management, and quality control.
The last pillar, Digital Transformation, is about a whole cultural and structural shift within the industry to create an environment around data-driven insights. That transformation is creating a digital ecosystem ready to run and monitor all processes continuously, optimizing them, and aligning them with the strategic goal of sustainability, efficiency, and safety.
Application of AI and ML across the Value Chain
With AI and ML, the steel manufacturing value chain is getting increasingly dependent on companies’ ability to solve logistics, resource allocation, production challenges, etc. AI application in mining exploration plays a key role in finding viable mining sites, expediting the land clearance process, and building optimized mining plans. Geological data is analyzed by machine learning algorithms which then determine the best areas for mining to increase efficiency and lower the operational cost.
In asset monitoring, sensors are attached to critical equipment such as pumps, fans, and conveyor belts that monitor vital parameters such as temperature, vibration, and noise. Such real-time data also provides operators with the ability to predict potential malfunctions ahead of time and to proactively manage maintenance requirements without downtime. While AI-driven models offer prescriptive insights, they also offer insights about specific actions such as tightening loose bearings or correcting misalignments.
In addition, digital twin technology is transforming operations in blast furnaces, the key to converting iron ore into molten iron. These complex systems are optimized by AI models to predict important parameters like cohesive zones for gas utilization and the distribution burden of materials. By simulating various conditions and adjusting inputs, the digital twin enables operators to improve productivity reduce fuel consumption, and increase product quality.
Case Studies in Digital Implementation
AI-powered solutions have been seamlessly integrated across different production stages in steel manufacturing and have been highly successful. Blast furnace optimization is one such notable advancement. Precise control over the furnace environment is provided by AI models for the prediction of cohesive zone and silicon level forecasting, which is coupled with a stable and efficient production cycle. Factors that are critical to consider include temperature, gas flow, and material characteristics to predict how various configurations will affect productivity and fuel efficiency.
A second important application is coke quality prediction. Until recently, the coke quality has traditionally been evaluated before its introduction into the blast furnaces, verification taking place only after processing. But, with machine learning models, operators can now accurately estimate coke properties to as high as 95 percent. This capability makes use of data from different sources and blending processes to provide control over raw material quality and more consistent and efficient furnace performance.
At the same time, advances in digital have also improved conveyor belt monitoring. Video analytics leveraged by machine learning will be able to detect foreign material or mechanical problems in conveyor systems and prevent potential disruptions. The real-time alerts address the issue of misalignment, wear, or unexpected obstructions thereby reducing the chance of breakdown and ensuring smooth operations.
Building a Sustainable Future through Energy Efficiency and Green Steel
The steel industry's highest ambition is to produce 'green steel' — steel made with as little carbon emissions as possible. In this regard, energy-saving measures are being carried out in blast furnace critical areas. The use of AI allows for furnace environment control, fuel consumption reduction, and gas utilization improvement. Not only does this help increase productivity, but it is also in line with global sustainability goals to reduce carbon footprints.
Furthermore, AI-based predictive maintenance also reduces energy waste by keeping the machinery in the best shape possible so it does not require repairs and replacements. In energy management across plants, real-time opportunities for energy savings and waste reduction are also identified by AI models.
Envisioning the Digital Transformation Roadmap
The steel industry needs a structured roadmap to achieve complete digital transformation. This journey starts with a deep understanding of the current digital maturity level and a phased solution to fill the gaps that are identified. So, companies hire digital consultants for their insights and to create a good plan.
First, one needs to evaluate the current state of digital maturity and define an overall plan to reach the goals going forward. This is foundational work that must be completed to succeed with digital initiatives. Companies then begin to focus on where to implement digital solutions over two years, embedding them across as many plants as possible to measure the benefit of each initiative.
Finally, the successful long-term is dependent on a robust digital ecosystem. It includes building a cloud infrastructure or a virtualized environment to make data accessible, scalable, and more secure. Using virtual platforms, organizations can improve their ability to manage various applications and data to run existing operations while preparing for the future.
The Role of AI in Future Innovation and Expansion
With the dawn of AI and ML in the steel industry, the innovation potential is huge. Raw material inputs can be used to predict product quality in predictive models that evolve to forecast product quality based on a combination of raw materials, or new materials can be integrated into production models where there is little testing. Continuous refinement of AI algorithms can reduce reliance on traditional trial-and-error methods and lead more quickly to data-driven decision-making. In addition, as companies grow their businesses internationally, AI will be critical for alignment across borders, for maximum production, and for meeting environmental and safety standards. Real time analytics will enable the steel manufacturers to quickly adapt to the changes in the market and therefore provide them with a significant competitive advantage.
