Calcium-iron cored wire (CaFe Cored Wire) is an alloy additive material used in the steel smelting process. It consists of a mixture of calcium and iron powders encapsulated in a metal skin and is widely used in steelmaking and foundry applications.
CaFe Cored Wire Characteristics
1. Stable composition: The composition of calcium-iron cored wire can be precisely controlled to ensure that a predetermined amount of calcium and iron can be steadily added during the smelting process.
2. Efficient Utilisation: By adding in the form of core wire, the utilisation rate of calcium and iron can be significantly increased and wastage can be reduced.
3. Ease of operation: The use of alloy additives in the form of cored wire simplifies the operating procedures and reduces the burden on labour and equipment.
4. Uniform distribution: After the core wire enters the molten steel, the alloying elements can be uniformly distributed in the molten steel, improving the metallurgical effect.
5. Reduction of impurities: The use of cored wire can effectively reduce the introduction of impurities in the process of alloy addition, improving the purity and quality of steel.
CaFe Cored Wire Applications
1. Deoxidiser: Calcium-iron coated wire is used as a highly efficient deoxidiser in the iron and steel smelting process, which can remove the oxygen in the molten steel, reduce the oxides inclusions in the steel and improve the quality of the steel.
2. Desulphurising agent: Calcium iron has good desulphurising effect, which can reduce the sulphur content in steel and improve the mechanical properties and corrosion resistance of steel.
3. Alloying agent: By adding calcium iron cored wire, it can be alloyed in the smelting process to adjust the composition and properties of steel.
4. Modifier: In the casting process, calcium-iron cored wire can be used as a modifier to improve the organisation and properties of the castings, and increase the mechanical strength and toughness of the castings.
Manufacture of CaFe Cored Wire
The manufacturing process of calcium-iron cored wire generally includes the following steps:
1. Powder preparation: Calcium-iron alloy powder is prepared in a certain proportion and dried.
2. Coating: Use special equipment to coat the calcium-iron alloy powder in a metal skin (usually steel strip) to form a continuous core wire.
3. Moulding: Through drawing and shaping process, the core wire is made to reach the required diameter and length requirements.
4. Packaging: The finished core wire is coiled and packaged for easy transport and use.
