Improved Process Control (Neural Networks)

Improved process control can help to reduce electricity consumption significantly, while also providing additional benefits of improved productivity, reduced costs, and increased equipment life time. Modern controls using a multitude of sensors can achieve these to a greater extent than older controls. Such modern systems integrate real-time monitoring of process variables, such as steel bath temperature, carbon levels, and distance to scrap and real-time control systems for graphite injection and lance oxygen practices.  beyond that achieved through classical control systems. Neural networks or “fuzzy logic” systems, for example, analyze data and emulate the best controller.

Improved Process Control (Neural Networks)Costs & Benefits

Parent Process: Electric Arc Furnace
Energy Savings Potential

Electricity savings of 30 kWh/t-steel are estimated, and values may change based on scrap and furnace characteristics. (APP, 2010. p. 79)

CO2 Emission Reduction Potential

Emissions reduction potential of the technology is 17.6 kg CO2/t-steel (US EPA, 2010. p.11).

The State–of-the-Art Clean Technologies (SOACT) for Steelmaking Handbook

 

The State–of-the-Art Clean Technologies (SOACT) for Steelmaking Handbook is developed as part of the Asia-Pacific Partnership on Clean Development and Climate program and seeks to catalog the best available technologies and practices to save energy and reduce environmental impacts in the steel industry. Its purpose is to share information about commercialized or emerging technologies and practices that are currently available to increase energy efficiency and environmental performance.
