Application:
Mainly used in outside furnace refining, and is extensively adopted as deoxidant and desurphrizer, to change the forms of all kinds of impurity, so as to promote the quality:
1) Act as the controller in low adjusting steel ingredients
2) To large extent improving alloy receiving
3) Avoiding gas into steel liquids
4) What it is by way of Ca the effect changes the inclusion form to can purity the molten steel in the steel and get the oxygen and sulphur content is low pure steel
5) Strong adaptability and widely application

Remark: the alloy core-covered wires shall be covered securely, with straight seams, without leaking of powder, or empty covering, looking bright and clean.
Packing: 500kg, 1000kg, 2000kg per coil, sealed packing, or as per the requirement of customers.

We also can supply other alloy cored wire, the inner alloy or metal may be Ca, CaFe,,CaSiBa, CaAl, Mg, Al, S, TiFe and CMnFe. The diameter is 9mm or 13mm, or as per your requirement.
