High Grade CaFe Cored Wire

After tapping of steel from a primary steelmaking furnace such as BOF, EAF or EOF, molten steel for high quality or specialty applications is subject of further refining in a number of processes known as ladle metallurgy, sometimes also called ladle refining, secondary steelmaking or secondary metallurgy.

The additives for this refining can be added as bulk, but introducing metals and alloys in this way into the melt is sometimes problematic. Since the 1980s, the use of cored wires became widely spread as it offers numerous advantages: precise additions, much better levels of recovery and reproducibility.

The cored wire is manufactured by encapsulating powders in steel sheaths, the wires is coiled. Wire diameters range from 5 to 18 mm, their injection is carried out using with specially designed wire feeders.

The calcium iron cored wire functions as the deoxidizer and the desulfurizer in the process of steel-smelting production, mainly applied to cold heading steel, pipe line steel, and other low-silicon steel types. Its core power material is metal calcium and pure iron powder. Its deoxidized outcome – CaO is also mingled and combined with Al2O3 system in the liquid steel to generate 7 Al2O3.12CaO sinter of low-melting point, thus to avoid the effect of nozzle blockage arising from condensation of casting nozzle mingled with Al2O3 system, so as to ensure a smooth continuous casting production. The desulfurized outcome floats upwards very easily to be removed, so as to enhance the plasticity and tenacity of steel.
