A cored wire consisting of an inner calcium wire surrounded by an aluminum sheath forming a composite core which in turn is encased in a steel jacket. The cored wire is formed continuously by covering an extruded calcium wire with aluminum then inserting the aluminum covered calcium wire into a steel jacket in a roll forming process. Also disclosed is a method of reducing splashing when introducing calcium metal into a molten ferrous metal bath.

Method for treating molten metal with cored wire

Cored wire for treating molten metal

A cored wire continuously formed by continuously inserting an extruded core inside a continuously roll formed sheath, the peripheral edges of the roll formed sheath joined by a continuous lock seam. Inspection of the partially formed lock seam at a designated process step serves to warn the user of malformed or defective lock seam portions in the finished cored wire.
