Seamless pure calcium cored wire description :
The cored wires are widely used for calcium treatment and microalloying in the ladle metallurgy, which have the advantages of element precise control and easy use.Calcium is used to transform alumina into low melting point calcium-aluminates, avoiding nozzle clogging as well as to control the shape of oxide and sulfide inclusions.
Advantages:
Long-term to store (long time storing calcium won’t lose efficacy.
More exact, stable for calcium content (52g/m)
High recovery rate(the same treatment effect, the little consumption)
High reproducibility (low fluctuation of residual calcium)
Little harmful gas be absorbed (H, N etc.)
In the feeding process, the less inclusions it carries, the better for the clean molten steel .
Eliminate alumina nozzle clogging, spheroidize oxide and sulphide inclusions which increases the tranverse toughness and strength of steel. Improve steel purity.
