the specification and usage of cored wire
Cored wire is a kind of ferro alloy, which will to break all kinds of additive(deoxidizer, desulfurization agent, inoculant, alloy etc.) into a certain size that joins in the liquid steel or iron liquid. Then using cold rolling low carbon steel belt to make a composite material with arbitrary length, which is mainly used in three aspects including the breeding, refining outside the furnace, special alloying element.
The cored wire has many varieties: calcium ferro cored wire, pure calcium cored wire, calcium silicon cored wire, calcium aluminum cored wire, rare earth cored wire and carbon cored wire and so on.
The cored wire is suitable for steelmaking and casting. For steelmaking, cored wire can purify steel inclusion shape, improve the castability of liquid steel and using performance of steel, and increase the yield of alloy, reduce the cost of steelmaking. Economic benefit is remarkable.The Advantages of Cored Wire:
- Cored wire ferroalloy is easy to adjust and control the contents of oxidation element and micro element, as well as can greatly improve the alloy yield, reduce the smelting cost, shorten the time of smelting and precise control components.
- Cored wire can have impact on pure liquid steel and change inclusions properties and morphology and improve the quality of liquid steel and casting state.
- Cored wire is divided into draw-off and outgoing two kinds. What is more, the production line of cored wire required mechanical equipment is simple and reliable, and covers an area of less, in particular, in the draw-off packet cored wire are more comfortable with narrow places.
