Cafe Cored Wire

The active element in CaFe is calcium. CaFe blends are used for the treatment of Aluminum killed steel.

Full Name:                                   Calcium Iron

Type of product:                          Blended Ca with Iron

Melting point (Ca):                 839°C (1558°F)

Boiling point (Ca):                       1484°C (2703°F)

The active element in CaFe is calcium.

CaFe blends are used for the treatment of Aluminum killed steel.

The low density and the low boiling point of pure Calcium require special addition methods. Cored wire is the most efficient technology to introduce Calcium into liquid steel in order to get high performance/recovery.

With its strong affinity for oxygen and sulfur, Calcium has a secondary effect on deoxydation and desulfurization. It forms CaO first, followed by oxysulfides and finally sulfides CaS.

The Calcium treatment of liquid steel is essential with the objective of combining calcium with alumina and sulfide inclusion in order to control shape, distribution and fluidity of the modified inclusions with following beneficial effects:

­ 1)Avoid silicon pick up (Calcium is Silicon free)

­ 2)Reduced caster nozzle clogging by alumina (Al2O3) inclusions resulting from previous aluminum deoxydation

­ 3)Globularisation of alumina and complex inclusions improve of the transverse properties of the steel: Ductility and strength

­4)Improvement of steel cleanliness

Typical chemical analysis:

Almost any kind of blends can be produce and the most common are:

CaFe20                                                   CaFe30

Ca: 20%                                                   Ca:   30 %   

Fe:    Balance                                          Fe: Balance

Variations to these main elements and other residuals can be addressed on a case-to-case basis.
