How Can Lime Injection Improve Your Costs

Lime is a critical component in EAF steelmaking, and both the quality of your lime and the method through which it is added to the furnace can directly impact steel quality and your production costs.

How can lime injection lead to cost savings?

• Raw Material Savings: By injecting lime and dolime directly into the bath, lime injection minimizes the chance of lime particles being lost to through the baghouse or accumulating on your shop floor. This can lead to a significant 7-15% reduction in lime consumption, and less lime waste equals direct material cost savings.
• Energy Savings: More efficient lime utilization enables steelmakers to have better control over slag chemistry. Process improvements can result in reduced melting power and overall energy savings in the furnace. Consuming smaller sized lime also requires less energy to melt the material into solution.
• Savings on Consumables: Lime injection efficiencies can reduce consumable expenses by extending the lifespan of electrodes and the refractory. In the long run, this can have a significant impact on costs.
