What Is CaFe Cored Wire?
CaFe Cored Wire, also known as Calcium Iron Cored Wire or Ferro Calcium Cored Wire, uses a calcium-and-iron core enclosed by an outer steel strip for controlled calcium addition during secondary steelmaking. Unlike CaSi cored wire, CaFe Cored Wire introduces calcium without relying on a silicon-bearing alloy core.
This makes CaFe Cored Wire particularly relevant when calcium treatment is required but additional silicon input needs to be limited. The iron-bearing core also makes it easier to introduce calcium without significantly changing the existing silicon balance of the steel.
Among the other cored wire grades for steelmaking, CaFe Cored Wire can be considered when the treatment target requires calcium addition with an Fe-bearing carrier rather than CaSi.
CaFe Cored Wire Specifications
When confirming a CaFe Cored Wire specification, the calcium content, filling weight, steel strip thickness and wire diameter should be checked together. These parameters affect both the amount of calcium introduced per metre and compatibility with the existing wire-feeding system.

CaFe Cored Wire for Steelmaking
Cold Heading Steel Production
In cold heading steel production, CaFe Cored Wire can be used during secondary refining when calcium treatment is required without introducing additional silicon from a CaSi alloy source.
Controlled calcium addition can support inclusion modification before casting, while the feeding amount should be matched to the steel chemistry and the established refining practice.
01
Pipeline Steel Production
Pipeline steel production requires close control of steel cleanliness and composition before continuous casting. CaFe Cored Wire provides calcium through an iron-bearing core and can be considered when calcium treatment is required while further silicon addition needs to be limited.
The required addition should be adjusted according to the steel grade, sulfur and oxygen conditions, and the plant's inclusion-control target.
02
Low-Silicon Steel Production
CaFe Cored Wire is particularly suitable for low-silicon steel grades where the remaining silicon range needs to be controlled carefully. Unlike CaSi cored wire, it uses a calcium-and-iron core rather than a silicon-bearing calcium alloy.
This allows calcium treatment to be carried out with less impact on the existing silicon balance when the steel chemistry is already close to its target composition.
03
Low-Carbon and Ultra-Low-Carbon Steel Production
For low-carbon and ultra-low-carbon steel, the remaining chemistry window can become relatively narrow during final refining. CaFe Cored Wire can be considered when controlled calcium addition is required without introducing unnecessary silicon from the calcium source.
The final wire specification and feeding practice should be matched to the steel grade, target calcium addition and existing secondary-refining conditions.

Why Choose CaFe Cored Wire?
Calcium Addition Without Additional Silicon
The main selection advantage of CaFe Cored Wire is that it provides a calcium-bearing addition without using a CaSi alloy core. This can be useful when the steel requires calcium treatment but further silicon input is not preferred.
Iron-Bearing Core Material
CaFe Cored Wire uses calcium together with an iron-bearing carrier. Compared with a silicon-bearing calcium alloy, the Fe-bearing core provides another route for calcium addition when the remaining chemistry window needs to be controlled.
Controlled Filling Weight per Metre
The amount of core material contained in each metre of CaFe Cored Wire is an important part of the product specification.
When the filling weight remains consistent, the steel plant has a clearer basis for relating the required alloy addition to the feeding length. This becomes especially important for repeat orders where feeding parameters have already been established around a particular wire specification.
Consistent Wire Specification for Feeding
Wire diameter and steel strip dimensions should remain within the confirmed specification so that the supplied wire remains compatible with the existing feeding system.
For this reason, CaFe Cored Wire should be selected by its complete specification rather than by the product name alone.
When to Choose CaFe Cored Wire
The choice between CaFe, CaSi and Seamless Pure Calcium Cored Wire depends on how calcium needs to be introduced and which accompanying elements can still be accepted in the steel.

CaFe Cored Wire |
Ca with Fe-bearing carrier |
When calcium treatment is required and additional silicon needs to be limited |
|
CaSi Cored Wire |
Ca + Si |

|
Seamless Pure Calcium Cored Wire |

CaFe Cored Wire can therefore be considered when calcium needs to be added while further silicon input is restricted. The final selection should still take into account the steel grade, target calcium addition, filling weight, wire diameter and existing feeding conditions.
CaFe Cored Wire Quality Control
Quality control for CaFe Cored Wire covers both the core material and the physical wire specification. For repeat supply, consistency in these parameters is important because changes in filling weight or wire dimensions may affect an established feeding practice.
Calcium Content
The calcium content of the core material should be checked against the confirmed chemical specification for the order.
Filling Weight per Metre
The core filling weight is checked because it determines how much CaFe material is contained in a defined feeding length. For the specification shown on this page, the listed inside powder weight is 230–250 g/m.
Wire Diameter
The finished CaFe Cored Wire diameter is checked against the confirmed specification. The listed diameter is 13 ± 0.5 mm, which should also be considered in relation to feeder compatibility.
Steel Strip Thickness
The steel strip is checked against the agreed physical specification. For the listed CaFe Cored Wire, the strip thickness is 0.4 ± 0.2 mm.
Batch Inspection
For commercial supply, the delivered CaFe Cored Wire should correspond to the specification confirmed before production. Where batch inspection records or COA are available for the order, they can be used to compare the supplied material with the agreed requirement.
CaFe Cored Wire Packing & Supply
CaFe Cored Wire is supplied in coils for storage, handling and wire feeding at the steel plant. Before production, the required Ca specification, wire diameter, filling weight, quantity and packing requirements should be confirmed with the order.
If you already use CaFe Cored Wire, you can send us your current specification sheet or COA for comparison. This gives us a clearer basis for checking whether the available specification matches the wire already used in your plant.
FAQ
Q: What is CaFe Cored Wire used for?
A: CaFe Cored Wire is mainly used for controlled calcium addition during secondary steel refining. It can be used as part of calcium treatment and inclusion-modification practice, especially when additional silicon input needs to be limited.
Q: What is the difference between CaFe and CaSi Cored Wire?
A: CaFe Cored Wire introduces calcium with an iron-bearing carrier, while CaSi Cored Wire introduces both calcium and silicon. CaFe can be considered when calcium treatment is required but further silicon addition is not preferred.
Q: What diameter of CaFe Cored Wire do you supply?
A: The CaFe Cored Wire specification shown on this page has a diameter of 13 ± 0.5 mm. The diameter should be confirmed together with the filling weight and existing wire-feeding equipment.
Q: Why is filling weight per metre important?
A: Filling weight indicates how much core material is contained in a defined length of CaFe Cored Wire. Keeping this value consistent gives the steel plant a clearer basis for relating feeding length to the required calcium addition.
Q: What information should I provide for a CaFe Cored Wire quote?
A: Please send us your required Ca content, wire diameter, filling weight, order quantity and destination port. If you already use CaFe Cored Wire, you can also send your existing specification sheet or COA for comparison.
