Ferroalloy cored wire is a metallurgical material used for steel smelting. It consists of an outer layer of iron sheet and an inner layer of alloy powder. The outer layer of iron sheet is usually made of thin steel strip, which has certain strength and corrosion resistance, while the inner layer of alloy powder is configured according to specific smelting requirements.

The main purpose of ferroalloy cored wire is to add alloying elements to liquid steel during the steel smelting process to adjust the chemical composition of the steel and improve the properties of the steel. By inserting the alloy cored wire into the liquid steel, the alloy powder can be quickly dissolved and evenly distributed in the molten steel, thereby achieving the purpose of accurately controlling the composition and properties of the steel.

Ferroalloy cored wire has the following advantages

Precise control of composition:

Precise control of the chemical composition of steel can be achieved to meet the requirements of different steel types.

Uniform distribution of alloy elements:

Alloy powder is evenly distributed in the molten steel, avoiding the problem of local alloy concentration being too high or too low.

Efficient addition:

The addition speed of ferroalloy cored wire is fast, which can improve production efficiency.

Reduce alloy waste:

Since the alloy powder is wrapped inside the iron sheet, the loss and waste of alloy can be reduced.

Cored Wire For Steel Making

Main Application Scenarios

(I) Steelmaking

Clean Steel Production:

Calcium silicon cored wire is used for deoxidation of cold-rolled steel sheets for automobiles and pipeline steel for nuclear power plants, reducing the oxygen content of liquid steel to below 20 ppm.

Specialty Steel Alloying:

Ferro Titanium cored wire is used in silicon steel production, precisely controlling the titanium content to increase magnetic permeability and reduce transformer core losses.

Continuous Casting Process Optimization:

Pure calcium cored wire treats molten steel in the tundish, preventing nozzle blockage and increasing the yield rate of continuous casting billets to over 99.5%.

(II) Foundry Industry

Rare earth silicon magnesium ferro cored wire is used as an inoculant for ductile iron, promoting graphite spheroidization and increasing the tensile strength of cast iron from 300 MPa to over 500 MPa, making it suitable for the production of precision castings such as engine blocks and pipe fittings.

(III) Other Metallurgical Applications

Blast furnace maintenance:

Calcium based cored wire is fed through tuyeres to repair erosion in the blast furnace lining and extend its service life.

Non-ferrous metal smelting:

Calcium aluminum cored wire is used for deoxidation of aluminum alloys, reducing oxide inclusions and improving the surface quality of profiles.
