Product Details:
Detailed Introduction
Product name: Calcium
Type: Calcium metal cored wire
Melting point: 834℃（1558°F）
Boiling point: 1484℃（2703°F）
Application:
The pure calcium cored wire is mainly used for Al-killed steel.Due to its low density, low boiling point and high oxidability, calcium needs to be released near the ladle bottom in order to have the best recovery. 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.
The advantages as below:
Eliminate alumina nozzle clogging, spheroidize oxide and sulphide inclusions which increases the tranverse toughness and strength of steel. Improve steel purity. Avoid silicon addition.
Specification
Dia 9mm cored wire is a kind of medium size wire, which is suitable for the ladle of capacity less than 20 MT and most of cast iron spheroidization
Φ9mm Cored wire Specification
* The above specifications can be adjusted upon request.
Dia 13mm cored wire is a typical size wire for steel industry, which is suitable for all kinds of steel ladles and alloys.
Dia 16mm cored wire is suitable for the alloy adding to the steel ladle of capacity more than 250MT.
Φ13mm - Φ16mm cored wire specification
* The above specifications can be adjusted upon request.

The above fill rates can be adjusted upon request. The thickness of steel strip is 0.35~0.50mm, which conforms to the stipulation of GB716、GB3526、GB1323. The weight allowance for each 200g is no more than 2.5%. The joints for each 1000 meters are no more than 3. 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. | ||||
Packing
Based on the design of feeding machine, cored wire coils can be made vertically or horizontally, With the special connector, the coils can be fed continuously, The packing also can be customized upon request.
