Powder Form :
Size: 0-3 MM Synthetic slag consists of prepared mixture of several individual oxides which is used during secondary steelmaking to assist the steel treatment in the ladle from the viewpoint of effective refinement.
Pre- Melted Calcium Aluminates :
Size 1-10 MM and 10-50 MM, Pre Melt Synthetic Slag is best known for its high capacity to absorb acidic impurities for example arsenic and antimony while presenting a wide, homogeneous liquid area when mixed with iron oxides. Pre Melt Synthetic Slag is used as deoxidizer, desulfuration, dephosphorization in steelmaking.
Size: 10-50 MM, Synthetic slags are used during steel treatment in the ladle from the viewpoint of effective refinement. Their basic task is formation of active slag for improvement of kinetic conditions of refining processes. In the steel industry, a number of synthetic slags based on Al2O3 are used which are produced from natural or secondary raw materials in different forms. However, the use of synthetic slags is influenced by the choice of used raw materials, by production technology and by final chemical composition. This paper shows plant results and experience with the utilization of briquetted synthetic slags based on Al2O3
