Product Casi Cored Wire     Price     Related information

Product Details:

Full Name:                                       Calcium silicide

Type of product:                              Ca bearing alloy (CaSi2)

Melting point:                             1010°C (1670°F)

Density at 20°C (68°F):                 2.40 g/cm3

Utilisation:

The active element in CaSi is calcium, CaSi alloy is more economical than pure calcium for the treatment of silicon killed steel.

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 so modified inclusions with following beneficial effects:

● Reduced caster nozzle clogging by the alumina (Al2O3) inclusions resulting from the previous aluminum deoxydation.

● Globularisation of alumina and complex inclusions and consequently improvement of the transverse properties of the steel: ductibilty and strength.

 ● Improvement of steel cleanliness.

Typical chemical analysis:

Ca   :    28 – 32 %

Si    :     57 – 62 %

Fe   :     Balance

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