Synthetic Flux


Calcium Aluminate based Synthetic slag builders are a kind of auxiliary material for refining during steel production. *Production The production of calcium aluminate is milled in an appropriate ratio to provide homogenous mixture. It is then sintered or melted in the oven. The targeted mineral composition is CA, CA2, C3A and C12A7.

* Application

Calcium Aluminate, used in steel production process, incorporates non-metallic emits by providing desulfurization and phosphorus removal without adversely affecting Crucible Refractory.

It can also play a role in the Calcium Aluminate-based Synthetic Slag Thermal insulation; It purifies liquid steel by preventing liquid steel from reacting with Oxygen, Nitrogen and Hydrogen.

Calcium Aluminate for Metallurgy is a kind of auxiliary material for steelmaking,  as it speeds up secondary metallurgy process, especially faster desulphurization, Improves overall steel cleanliness and makes high grade steel with cheaper cost.

Calcium aluminate’ advantages

  • Uniform chemical compositions,low melting point,high melting speed,and short smelting time;
  • It has no fluoride and doesn’t erode furnace lining and ladle, and it is compact, non- absorbent, and easy to storage as well;
  • Stable phase and fast dus-treducing speed,rapid desulfurization effect stabilized at 60%,and suppresses phosphorus into molten steel;
  • Improving the protective effect and reducing erosion to ladle lining.
