What is cored wire

The cored wire feeding technology is a refining technology outside the furnace. In the process of modern metallurgy, it is usually necessary to add various solvents and trace alloys to the molten steel. This will cause a lot of waste. In order to improve the efficiency of microalloy and solvent utilization, cored wire was invented. Adding cored wire to molten steel with ladle wire feeding device has a very good metallurgical effect.

Cored wire is a composite alloy material. It is made from various alloy powder and pressed into steel strip. According to the type of raw material alloy powder, it can be divided into: calcium silicon cored wire, iron calcium cored wire, carbon cored wire. One of the most common products is the CaSi cored wire. The main raw material of CaSi cored wire is calcium-silicon alloy.

What are the advantages of cored wire?

1.It can increase the absorption of alloying elements and reduce their dispersion in smelting.

2.Various powders of different densities are mixed together as required. This eliminates the need to fuse the various materials evenly through melting.

3.At the same time, it can also save a lot of electricity and reduce the emission of harmful substances. Thus greatly reduce the employment and labor intensity, with good economic and social benefits.

Cored wire manufacturing process

The alloy material used as deoxidizer and desulfurizer is crushed into a certain particle size. And then it is wrapped into a composite material of any length with a steel strip.

The core wire is well compacted. The powder is evenly mixed. And the powder weight per meter is controllable and uniform.
