Understanding Your Market Needs

Producing quality steel, while keeping operating costs low is your number one priority. The foamy slag in a foundry’s electric arc furnace (EAF) helps to stabilize the arc, protecting the refractories, shielding metal from the atmosphere and improving energy efficiency reducing power-on time and repair time. Lime injection supports foaminess throughout the heat and controls the apparent viscosity of the slag, which increases the yield of the heat. It is also important to saturate the slag with dolomitic lime to promote the foaming and protect refractory lining. Additionally, adding hydrated lime supports the lubrication for the shaping process and the atmospheric protection of the final product.

Equipment and corresponding processes may also need updated or replaced over time from evolution of technology or normal wear and tear.

Solutions to Meet Your Needs

Let Carmeuse help your foundry furnace operations run more smoothly by protecting your slag and refractory performance, and aiding in casting removal.

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

Hydrated Quicklime

  • Provides a lubrication to the casting process to aid in easy removal
