Description
When the Silicon Calcium Cored Wire CaSi Wire is deoxidized in the ladle, it needs to be added through a wire feeder. We often see various surface shapes, such as polygons, circles, rectangles, etc., while the shape of the internal wire feeder is only circular. At present, the newly produced core wire can be used not only for surface feeding, but also for internal feeding. The cored wire manufacturer will introduce to you the design concept of cored wire.

The design concept is:
1. Core material of core-spun wire
In industrial production, calcium alloy core wires, such as CaSi core wires, can be obtained at a lower cost. The presence of calcium silica increases calcium production. In composite calcium core wires such as CAFE, silicon calcium cored wire CaSi wire are added to increase the density of the core wires. Under the same conditions, the calcium is added close to the bottom of the steel bag. What is really deoxidized is metallic calcium. From the perspective of the efficiency of steel enterprises and the reputation of the core industry, it is recommended to use high-density calcium reduced core materials.
2. Core sealing method
In surface feeding, bite and welding can be used. However, there is a triangular hole in the bite mark that can bring air into the molten steel. While top grooves can be added to reduce gaps, the core wire is prestressed on the inside and tends to curl when heated. Internal wire feeding, good welding method. It is recommended to produce and use welding core wire.
3. Core material to shell mass ratio
If the outside is too thin, the rigidity of the core wire will become weaker. When the surface is fed, the liquid level is in a suspended state and cannot enter the molten steel. If the casing is too thick, the heat required for melting will increase and the temperature of the ladle will drop. Therefore, choose a medium thickness, generally 0.6-0.7mm. Calcium treatment costs are significantly reduced when the external quality of the core material is higher. The quality of core materials produced and used should be between 1-1.2.
