  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 into 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 it’s low density and can also keep warmness.

  Application Functions

  Desulphurization

  Deoxygenation

  Impurities absorption

  Ladle lining protection
