Reducing electrode wear in the EAF process with ArcSpec

Nov 9, 2023

Electrode consumption is a major cost in EAF steelmaking and it’s not just about electrode quality; it’s also influenced by how we handle them in our EAF process. This post explains phenomena causing consumption and practices to reduce it.
One key aspect is the real-time control of voltage and current. By optimizing these variables, we can reduce electrode consumption. But it’s important to strike a balance to avoid damage to the furnace’s side walls. Monitoring the amount of unmelted scrap near the edges of the furnace allows us to adjust the arc length accordingly. This simple adjustment has been shown to reduce electrode consumption by up to 10% and extend the life of refractory materials, significantly cutting EAF operating costs.
Let’s make steel production more cost-effective and environmentally friendly!
