Carbon cored wire is a type of alloy cored wire used in the steelmaking industry. It consists of high-purity carbon additives crushed into specific particle sizes and then wrapped in steel strips. The main components include calcined anthracite coal, calcined petroleum coke, and graphitized petroleum coke. It is also known as solid carbon cored wire or pure carbon cored wire, sometimes abbreviated as C cored wire.
Functions and Advantages of Carbon Cored Wire
Carbon cored wire is used to adjust the carbon content in molten steel and has the following advantages:
- Purification of Molten Steel Inclusions: Improves the mechanical properties of cast steel.
- Enhances Alloy Efficiency: Reduces alloy consumption, lowering steelmaking costs and increasing economic benefits.
- Stable Carbon Recovery Rate: The carbon recovery rate is over 90% and stable.
- Extends Product Durability: Reduces production costs and has a long storage life.
Chemical Composition of Carbon Cored Wire
| Type | Main composition % | Inside powder weight (g/m) | Steel strip thickness (mm) | Line weight (g/m) | Cored wire diameter (mm) |
| C | C>90 | 130±10 | 0.4±0.05 | 300±10 | 13±0.5 |
Carbon Cored Wire Production Process
The cored wire machine produced using new technology is tightly wrapped, preventing spillage or leakage. The carbon powder is evenly filled and packed with waterproof plastic and steel frames.
Carbon Cored Wire Application
Carbon cored wire is widely used in steelmaking and casting industries, mainly for fine-tuning the carbon content in molten steel, replacing carbon additives. Its main component is graphite powder, which is high in purity, free of impurities, and low in moisture. When delivered to molten iron through equipment, it prevents waste and increases the iron content in molten iron.
Advantages of Using Alloy Cored Wire
- Prevents Impurities from Entering Molten Steel: Materials enter the bottom of molten steel, reducing bubble formation.
- Strict Control of Chemical Composition: Allows for easy control of alloy addition quantity and speed through the wire feeding machine.
- Reduces Production Costs: Increases alloy yield.
