Purging Refractories

The introduction of bottom gas purging into ladle was a major step in secondary steel metallurgy. IFGL manufacture tailored made gas purging refractories to suit gas permeability as per customer requirements, which offer highest operational safety and long service life.

Objectives of Ladle Purging

  • Desulphurization & Phosphorous removal.
  • Remove dissolved gases.
  • Purification of steel from non-metallic oxide inclusions.
  • Homogenisation of steel chemical composition.
  • Reduce thermal stratification.
  • Control of the steel casting temperature.
