Understanding Your Market Needs

Producing quality steel, while keeping operating costs low is your number one priority. High calcium lime is used to support the foamy slag in an electric arc furnace (EAF) helping to remove impurities in the steel and stabilize the arc, which in turn protects the refractories, shields metal from the atmosphere, improves energy efficiency, and reduces power-on time and repair time. It is also important to saturate the slag with dolomitic lime to promote the foaming and protect refractory lining.

Lime injection systems are becoming increasingly popular as a more efficient means to transfer the lime into the molten steel. Benefits of a lime injection system includes a reduction of lime usage, cleaner shop environment, better control of slag chemistry, energy savings and improved steel processing performance.

An evaluation of your lime handling equipment is essential in ensuring the lime is transferred from silo to furnace in the most effective and reliable way, as over time this will be impacted through normal wear and tear.

Solutions to Meet Your Needs

Let Carmeuse help your electric arc furnace (EAF) operations run more smoothly by protecting your slag and refractory performance with our high calcium and dolomitic lime. Additionally, our expertise in lime injection helps you save power-on time, energy consumption, refractories, and lime consumption, along with a safer and better environment.

High Calcium Quicklime

  • Optimizes chemistry of the slag, removing impurities like sulfur, carbonates, manganese, etc. from the bath to improve steel quality
  • Maintains the viscosity of the slag to increase heat yield
  • Supports foaminess throughout the heat
  • Controls the apparent viscosity of the slag, increasing the yield of the heat

Dolomitic Quicklime

  • Magnesium content prevents melt-throughs in the refractory
  • Adds magnesium to the bath to balance refractory
  • Protects the refractory
