CASI CORED WIRE

A Game-Changer in Steelmaking

CaSi (calcium silicon/silicocalcium) Cored Wire is a type of metal cored wire that is filled with silicon-calcium alloy powder and wrapped by a steel tubular wire, which is widely used in steelmaking and foundry processes by injected directly into the molten metal by a wire feeding machine, where it dissolves rapidly and uniformlyin. CaSi cored wire is versatile and can be used in both electric arc furnace (EAF) and basic oxygen furnace (BOF) steelmaking processes, offering flexibility in steel production methods.
CaSi (calcium silicon) cored wire can be customized according to specific needs, requirements of different steel grades and processes.

Applications of CaSi (Silicocalcium) cored wire in steelmaking The main functions of CaSi (Calcium Silicon/Silicocalcium) cored wire in steelmaking

1. The main function of CaSi (calcium silicon/silicocalcium) cored wire in steelmaking is to act as a deoxidizing and desulfurizing agent. It can also improve the performance, plasticity, impact toughness and molten steel flow of steel.

2. By using CaSi (calcium silicon/silicocalcium) cored wire, the oxygen content in the steel can be significantly reduced by forming silica gas with silicon.

3. CaSi (calcium silicon/silicocalcium) cored wire reduces the content of harmful elements in molten steel, such as sulfur and phosphorus, by chemical reaction, forming calcium sulfide with calcium. Additionally, alumina and manganese sulfide can be reduced by reacting with calcium and silicon.

4. CaSi (calcium silicon/silicocalcium) cored wire can change the shape of inclusions, fine-tune the ingredients, ensure the stability of metals, rare earth elements, and enhance fluidity, castability and mechanical properties of steel.

5. CaSi (calcium silicon/silicocalcium) cored wire has many advantages over other methods of deoxidizing and desulfurizing materials, such as:

- reducing the amount of precious elements added;
- reducing the refining cost;
- avoiding the oxidation and burning of the alloy elements by the air and the slag;
- reducing the oxygen and sulfur content and modifying the inclusions;
- reducing the environmental pollution, power consumption, gas evolution, and slag formation.

The benefits of using CaSi cored wire in steelmaking Why metallurgical factories are using CaSi cored wire in steelmaking and foundry process

1. Deoxidation. Degassing agent:

CaSi cored wire is rich in silicon elements, and silicon and oxygen are very easy to produce silica gas. Using CaSi cored wire in steelmaking can significantly reduce the oxygen content in the steel. The process is very stable, reducing the phenomenon of steel spatter, and improving the safety factor of the deoxidation process.

2. Reducing Harmful Elements:

The raw materials used in steelmaking contain a lot of sulfur, phosphorus, and other harmful elements. Through the use of CaSi cored wire, these harmful elements in the steel can be significantly reduced. This is mainly achieved by using the reduction of its internal calcium elements, which chemically react with the harmful elements, generating calcium oxides that float on the surface of the steel for easy handling.

3. Cost Reduction:

CaSi cored wire is not only cheaper than traditional steelmaking deoxidizers but also relatively widespread in the application. It can replace or reduce raw materials, thus achieving the role of reducing costs and enhancing the benefits of manufacturers.

*Conclusion:

CaSi metal cored wire plays a crucial role in improving the quality of steel, reducing costs, and enhancing the efficiency of the steelmaking process.

The advantages of using CaSi cored wire in steelmaking
over other methods of deoxidizing and desulfurizing materials include:

1. CaSi cored wire can provide a faster and more complete dissolution and distribution of the alloy elements than other materials, which may have low solubility, uneven distribution, loss of alloy elements during the melting process and poor fluidity in the melt.

2. CaSi cored wire can prevent the oxidation and burning of the alloy elements by the air and the slag, and reduce the power consumption, slag formation, gas evolution and environmental pollution.

3. CaSi cored wire can fine-tune the ingredients and ensure the stability of metals and rare earth elements, and effectively change the shape of inclusions and improve the castability and mechanical properties of steel.

4. CaSi cored wire can reduce the amount of precious elements and the refining cost, and increase the efficiency and quality of the steelmaking process.

How to use CaSi cored wire in steelmaking

To use CaSi cored wire in steelmaking, your factory needs to have a Wire feeding machine that can deliver the cored wire to the ideal position in the molten steel. There are two methods of using CaSi cored wire: inner tap and outer tap:

1. The inner tap method is to feed the cored wire directly into the ladle;

2. The outer tap method is to place the coiled wire on the turntable of the pay-off device and feed it into the ladle through a catheter.

You can also control the feeding amount and speed of the cored wire by using a display counter and a speed controller on the Wire feeding machine.
