Promote sustainable development of steel industry with digital technology

“Steel Industry carbon peak and carbon reduction action Plan” proposed: plan to achieve carbon peak by 2025; By 2030, carbon emissions will be 30% lower than their peak; Deep decarbonization of the domestic steel industry by 2060. Under the background of strict control of high energy consumption and high emission projects, green, low-carbon and sustainable development has become the top priority of the transformation and upgrading of the steel industry.

To achieve the above goals, the iron and steel industry is facing serious challenges such as tight time, heavy tasks and high pressure, and the use of digital intelligent manufacturing technology can effectively improve the production and management efficiency of iron and steel enterprises. At the equipment level, energy efficient motor and inverter technologies offer considerable energy saving potential for the steel industry, helping to improve system efficiency and reduce energy costs. Siemens is working with customers to promote energy efficiency upgrades in the steel industry by providing more targeted and more matched efficient motors, inverters and digital solutions through a deep understanding of customer needs. For example, SINAMICS S120, G120 inverter, wide power range, rich control methods, can be used for a variety of drive tasks.

Of course, achieving sustainable development cannot rely on energy-efficient equipment alone. At present, the energy data collection range of most steel mill customers is not comprehensive enough, and the intelligent control model is not mature enough, so it is difficult to calculate, manage and forecast the energy data, and there is still a distance from the intelligent balanced scheduling of energy. Based on the existing iEMS platform, equipment/process intelligent diagnosis products, and professional model algorithms, Siemens builds models with energy flow and branch plants as scene units, and combines platforms to form a comprehensive intelligent energy management and control platform suitable for the steel industry, improving enterprise energy efficiency and sustainable development capabilities. In the unmanned vehicle project at the raw material warehouse of Shagang pickling plant, Siemens Energy feedback program helped customers achieve an annual electricity savings of about 80,000 KWH.

Defense in depth to build a solid security cornerstone for the steel industry

With the acceleration of the digital transformation of the steel industry, industrial information security risks will also become more prominent, but information security must not become a reason to hinder digitalization. How can steel companies ensure data and assets are protected at all levels to reduce losses caused by industrial information security?

For the steel industry, executable, landable solutions are key. Siemens’ first industrial information security project in the steel industry has been completed in a steel enterprise in the western region. Siemens implements a variety of security measures based on the concept of “defense in depth” through the security assessment of the existing industrial network conditions in each workshop; Finally, the local industrial control situational awareness system is established. A variety of protective measures can prevent 99% malicious access and unauthorized access, reduce the incidence of 99% security incidents, reduce the loss caused by unplanned downtime, and effectively ensure the smooth operation of production.

For a long time, the development of Siemens and China’s steel industry has complemented each other. With deep industry insight and practical experience in the steel industry, Siemens will continue to deepen cooperation with steel companies to move forward in a more efficient, smarter, safer, greener and low-carbon direction. Siemens will be guided by digital consulting, combined with hardware and software accumulation, to help steel companies meet the needs and challenges from different stages of the life cycle.
