Types and uses of spheroidized cored wire

Spheroidized cored wire is a product of strip steel wrapped in strip-shaped alloy powder. Due to the difference of the wrapped powder, it can be divided into different uses. Steelmaking spheroidized cored wire is usually used as a deoxidizer, desulfurizer or carbon additive, such as CaSi spheroidized cored wire can be used as a deoxidizer and desulfurization in steelmaking agent. Carbon spheroidized cored wire can be used as carbon additive in steelmaking and casting. FeSiMg flux cored wire can be used as a nodulation agent in castings. 

The general data of steelmaking spheroidized cored wire is the weight of strip steel per meter and the weight of wrapped powder per meter. The thickness of spheroidized cored wire is generally 0.6mm, so the weight of strip steel is always 170g/m. For the weight of wrapped powder Weight, different alloys will have different data, for example, the weight of CaSi6030 and CaSi5528 cored wire is 230g/m, while for CaFe cored wire, the weight is 215g/mm, and for carbon cored wire, the weight is about 150g/m .

It should be pointed out that one type of steelmaking spheroidized cored wire is solid calcium cored wire, which is made by wrapping calcium wire with strip steel, because calcium wire is easy to react with oxygen, so Wrapped in strip steel, it will be easy to restore. When using spheroidized cored wire for steelmaking or casting, the smelted raw materials can be placed in the ideal position of molten steel, which can avoid the wrapped powder from reacting with air or slag, and can improve the absorption rate of smelted materials.
