Calcium Silicon Cored Wire

Calcium silicon cored wire is a type of cored wire made by wrapping calcium silicon alloy powder with steel tape through a cored wire machine. This alloy material has become an essential part of the ladle refining method in the processes of ironmaking and steelmaking, gradually becoming the preferred choice for steelmaking enterprises.

Features of Calcium Silicon Cored Wire

The core of calcium silicon cored wire consists of calcium silicon powder, and its outer sheath is made of thin steel tape. During the steelmaking process, the calcium silicon cored wire is fed into the ladle. Once the steel tape melts, the calcium silicon powder layer comes into direct contact with the molten steel, initiating a chemical reaction. This reaction, driven by argon stirring, effectively deoxidizes, desulfurizes, and removes inclusions, thus enhancing the quality and performance of the steel.

To achieve effective purification, calcium silicon cored wire must meet the following conditions:

• The active components in the core powder must thoroughly penetrate the molten steel.
• The core powder must have a strong capability to capture oxygen and sulfur atoms.

Although calcium is a strong deoxidizer, its light-specific gravity and low melting point make it prone to forming bubbles at high temperatures. Using pure metallic calcium as the core powder can cause the wire to burn upon entering the refining furnace, failing to achieve the desired purification effect and wasting calcium resources. Therefore, calcium silicon alloy powder is a more ideal choice.

Chemical Composition of Calcium Silicon Cored Wire

Advantages of Calcium Silicon Cored Wire

1. Reduced Molten Steel Agitation: Compared to the bulk alloy feeding method and powder spraying method, the wire feeding method using calcium silicon cored wire causes less agitation to the molten steel, reducing splashing and gas absorption.
2. Lower Temperature Loss: Using calcium silicon cored wire, the temperature loss of molten steel can be reduced to 5-7℃/min, which is 3-6 times lower than traditional methods.
3. Accurate Chemical Composition Adjustment: Depending on the aluminum and sulfur content in the molten steel, adding an appropriate amount of calcium silicon cored wire can accurately adjust the chemical composition.
4. Improved Inclusion Morphology: An appropriate amount of calcium silicon cored wire can thoroughly improve the morphology of inclusions in the steel, enhancing its purity.
5. Cost Reduction: The wire feeding method can effectively lower investment and operating costs.

Additionally, calcium silicon cored wire not only has a strong deoxidizing ability but also improves the floating of molten steel, enhancing the plasticity, impact toughness, and fluidity of the steel. This results in high-quality steel production and can even replace aluminum for final deoxidation.

Advantages Of Using Wire Feeding Method To Feed Calcium Silicon Cored Wire

The wire feeding method involves feeding the refining agent into the ladle in the form of wire after the molten steel is tapped from the steelmaking furnace. This method includes deoxidizing wire feeding, desulfurizing wire feeding, inclusion control wire feeding, and alloying wire feeding, depending on the refining purpose. Common refining agents include calcium silicon alloy powder in calcium silicon cored wire and calcium particles and iron powder in calcium iron cored wire.

Wire feeding equipment is simple in structure, easy to operate, occupies a small area, requires low investment, and is safe and reliable. During operation, it has low processing costs, no smoke or dust, minimal temperature drop (5-7℃), low molten steel absorption, no refractory material or carrier gas consumption, and high alloy absorption rates. Therefore, the wire feeding method for calcium silicon cored wire is an effective way for deoxidizing, desulfurizing, micro-adjusting alloy composition, and controlling inclusion morphology in molten steel.
