Secondary Steelmaking
Cored Wire Application
 Description:
Pure calcium solid cored wire, foreign steel plants
used it for processing molten steel since 1970s. It
has been widely used in the world nowadays. Especially
a long with raise of thin plate continuous casting technology
in 1990s, the advantages of the pure calcium solid cored
wire has been recognized by most of well-known steel
companies.
Cored wire is fabricated into a tubular wire with
a calculated mixture of alloys uniquely blended together;
such as CaSi, Carbon, etc. The blended mixture is then
metered into the wire during the fabrication process,
producing special alloy cored or flux cored wire in
various diameters, depending on customers’ requirements
and needs.
Applications:
 Cored
Wire injection application has replaced the injective
refractory lance powder injection method and proven
to be integral feature in the secondary metallurgical
treatment process where the advent of high-speed continuous
casting and increased quality requirements calls for
more stringent chemistry demands, shorter process time
and exact process repeatability.
Cored wire is a product where powdered elements are
tightly encased in steel sheaths and formed in round
shape of various diameters, depending on the various
requirements of the costumer and is supplied packed
level-wound in steel cages.
Cored wire Is injected deep into the steel bath using
a wire feeding machine, eliminating problems associated
with alloying elements of low density and melting point,
high toxicity and high affinity for oxygen and nitrogen.
Process:
Cored wire is well compacted, uniformity of powder mixes
and controlled and homogeneous powder weight per meter.
Advantages:
- Higher yields
- Less fume emission
- Solves handing of toxic and oxidized elements
- Accurate and repeatable results
- Lower gases pick-up
Products:
CaSi, café, Pure Ca, S Fe, CaAlFe, FeTi, S, FeB,
FeSiMg, CaSiMg.
