The main advantage for the cored wire process is the option of treating high sulphur base iron directly without a separate desulphurizing addition. The tundish cover process will be most efficient if base iron sulphur is restricted to maximum 0.03% S. Closely connected to sulphur removal is the inoculation effect from the treatment process.

Article: Soldering stainless steels
Thorough cleaning of the steel surface in the joint area is the key to successful soldering. Oil and grease may be removed with solvents, and wire brushing (with stainless steel brushes) or abrading with emery cloth can be used to eliminate other forms of contamination, leaving a bright, metallic surface.
Calcium | Miller and Company
The most widely used method for intergrated steel appliions is in the form of cored wire. This is mainly because calcium has a low density and high reactivity in the ladle making it difficult to introduce and retain in the melt.

How and why alloying elements are added to aluminum
The most common appliions for the 1xxx series alloys are aluminum foil, electrical buss bars, metallizing wire and chemical tanks and piping systems. The addition of alloying elements to aluminum is the principal method used to produce a selection of different materials that can be used in a wide assortment of structural appliions.

Dyudkin et al. used magnesium bearing wire and lowered the sulfur concentration from 510 to 400 ppm during the 3 min when the wire was inserted. The sulfur concentration then fell to 140 ppm during the subsequent 36 min of floatation under the influence of a slag in a 10‐ton ladle. 3 Their results agree also very well with the present work.
