Synthetic Calcium Aluminate Slags 

 

Keywords

synthetic calcium aluminate slags, premelted refining slags, calcium aluminate, premelted calcium aluminate, flux

 

Introduction

At present, most steel plants in the world generally adopt Ladle refining, to reduce gas inclusion and make molten stell evenly, in order to realize high yield, high quality and low cost steel making. So Synthetic Calcium Aluminate Slags is designed and manufactured to meet the above requirement and take a very important role in steel refining.

 

Properties 


  • Low molten point, fast molten, shorten refining time and energy consuming.
  • Good fuidity, desulphurization and inclusion reducing
  • No flame, little dust emission and good safety in use
  • No water absorption and no metamorphosing
  • Effectual submerged arc, and reduce electric arc to burn and erode ladle lining, and enhance ladle life.

Application Method 

Adding Calcium Aluminate in the furnace. Dosage: one ton molten steel needs Calcium Aluminate around 2-10 kg, and density of molten steel is greater than Calcium Aluminate. Then, argon gas is pumped in from the bottom of furnace, it drives the calcium aluminate to mix with the molten steel completely. Meanwhile, the molten Calcium aluminate adsorbs sulphur substance. Finally, dregs will suspend on the surface of molten steel due to its low density and can also keep warmness. 

 

Application Functions


  • Desulphurization
  • Deoxygenation
  • Impurities absorption
  • Ladle lining protection
