types of silicon calcium cored wires

Silicon-calcium wire is only one of many cored wires, and it is also a more common steel-making shop assistant material on the market. In the process of steelmaking, you can add a good amount of silicon-calcium wire to achieve a good deoxidation and desulfurization effect, thereby improving the performance of the steel, improving the plasticity, impact toughness and fluidity of the molten steel, and also directly entering the steel It has the characteristics of melting in liquid and uniform distribution. With the development in recent years, the production technology of cored wires has become more and more mature, and the types of cored wires have become more and more diverse. In addition to the core powders, which types can be divided into different types, How about it?

 

According to different sectional shapes of cored wires, they can be divided into rectangular cored wires, round cored wires without top hooks, and round cored wires with top hooks.

According to the different sealing methods of cored wire, it can be divided into bite cored wire, welded cored wire and lap cored wire. Bite-type cored wire refers to the core steel wire interface is formed by mechanical occlusion. Its process characteristics are simple forming process, good sealing, tight powder filling, and small powder quality error per unit length. Welded cored wire refers to the forming of the steel strip interface of the cored wire through welding. Its process characteristics are good sealing and tight powder filling, but the forming and welding equipment is complicated, and the powder error per unit length is large. Lapped cored wire refers to the cored steel strip interface is formed by overlapping. Its process characteristics are simple forming process, small powder quality error per unit length, but poor sealing and easy opening.

According to the different types of cored wire rolls, the cored wire can be drawn in and out according to the way of pulling out the cored wire, and it can be divided into vertical and horizontal according to the placement method.

However, both silicon-calcium wires and other types of cored wires are mainly used in steelmaking for desulfurization, deoxidation, alloying, microalloying, modification of inclusions in steel and calcium treatment of continuous cast steel ; In cast iron production, it is mainly used for alloying, desulfurization, spheroidizing, creeping, and inoculating treatment of cast iron. I hope that this information about cored wires will help you to understand cored wires further.
