Metal Cored Wires

 

Metallurgical cored wire is designed to introduce powdered or granular treatment materials into molten steel or molten iron. The outer steel strip protects the core material during handling and allows the wire to be fed into the melt through suitable feeding equipment.

You can also review our metallurgical cored wire product range for other core materials and wire specifications.

For carbon cored wire, the core material provides the required carbon addition. Compared with adding loose carbon material directly, cored wire feeding can provide more controlled addition and reduce material loss during handling and feeding.

 

Carbon cored wire is mainly used where controlled carbon adjustment is required during metallurgical processing.

• Carbon adjustment in molten steel
• Composition adjustment during secondary metallurgy
• Cast iron and foundry production
• Controlled addition of carbon-bearing material into molten metal

The actual amount of wire required depends on the starting carbon content, target chemistry, core composition and carbon recovery in your process.

 

Controlled Carbon Addition

Cored wire allows carbon-bearing material to be introduced at a controlled feeding rate, making it easier to manage the required addition amount.

Reduced Material Loss

The steel sheath helps contain the core material during storage, handling and feeding, reducing dust and loose material loss compared with direct powder addition.

Direct Feeding into Molten Metal

The wire can be fed below the melt surface with suitable equipment, helping the core material enter the molten metal rather than remaining only on the surface.

Suitable for Controlled Wire Feeding

Carbon cored wire can be used with wire-feeding equipment, helping control feed length and addition quantity during production.

 

Cored wire performance depends on more than the core composition alone. Before ordering, the wire specification and actual metallurgical process should be considered together.

• Compatibility with your wire-feeding equipment
• Core material composition and consistency
• Steel sheath quality and wire integrity
• Required feeding rate and addition quantity
• Storage and moisture protection requirements
• Actual carbon recovery under your production conditions

 

The following information is based on the current carbon cored wire product specification. Final technical requirements should be confirmed according to your purchase specification before production and shipment.

Specification note: Final core composition, wire dimensions and other technical requirements should follow the agreed purchase specification and batch inspection results.

 

To select the correct carbon cored wire, the product specification and the metallurgical process should be considered together.

If your process requires calcium treatment rather than carbon adjustment, the core material should be selected separately. You can also review our Ferro Calcium Cored Wire for calcium-bearing metallurgical treatment applications.

 

For metallurgical cored wire, stable feeding depends on both core material quality and wire construction. Quality inspection should therefore follow the agreed order specification rather than only checking the core material name.

• Core material composition
• Batch consistency
• Wire appearance and integrity
• Steel strip wrapping condition
• Wire dimensions when specified
• Packing condition
• Final inspection before shipment

For calcium-treatment applications, different core materials can behave differently in the melt. Our guide on CaFe vs CaSi Cored Wire explains the main factors to consider when selecting calcium-bearing cored wire.
