Cored wire

Cored wire is a thin-walled steel tube filled with a powder filler. It is used in metal smelting to adjust quality characteristics.

We offer various product modifications according to customer needs. Metallurgical cored wire can differ in terms of filler compositions, diameters, profiles and sheath thicknesses, coil sizes, metal frames and orientations of the coil axis in the package.

 

Wire applications

Wire applications

Cored wire is used in virtually all steelmaking workshops and foundries for steel and iron, and is also added to metal ladles at the intermediate or final stage of melting. This allows for precise dosing of fillers, ensures their high and stable absorption and uniform distribution throughout the molten metal, making cored wire the main and reliable element for precision metal processing.

The use of cored wires helps reduce the consumption of materials required to adjust the chemical composition of the metal, alloy and modify steel and cast iron, increase the degree of filler material extraction by the melt by reducing flyaway losses, and improve the environmental safety of the production process.
