CORED WIRES – Essential for the production of high-quality steel and spherical graphit cast
Cored Wires are the first choice when alloying elements like Calcium, Magnesium and Aluminium needs to be injected into molten metal for improving its properties, deoxidation and desulfurization. The technology allow for a precise and cost-effective addition of the alloying elements into the melt. Thus, the technology became essential in the steelmaking process as well as for foundries.
Essential for steel production
The alloying elements can be added efficiently into the steel production process at various stages, e.g. in Ladle Treatment, in Secondary Metallurgy, such as in Vacuum Degassing, up to the Continous Casting. Also for the production of special steels such as high-strength, low-alloy steel (HSLA) the Cored Wire Technology is essential, just to name one of the many applications. The Cored Wire is fed into the melt, where it melts and the filling elements reacts with the steel to achieve the desired effect, such as removing impurities, controlling grain size, and improving the mechanical properties of the produced steel. Compared to other methods, the Cored Wire technology allows for a precise and cost-efficient addition.
Indispensable for foundry industries
As treatment method in foundries the Cored Wires filled with Magnesium granule or other alloying elements such as Silicon or Carbon, it is specially used to produce cast iron with spherical graphite. Cast iron with spherical graphite is an iron-carbon-silicon casting alloy that has better mechanical properties than cast iron with lamellar graphite. It combines and good castability with strength and toughness values similar to steel and is suitable for the production of complex cast parts that are subjected to high mechanical and thermal stresses, e.g. automotive, marine or mechanical parts.
