Ferro alloy cored wire

Ferro alloy core-wire is a kind of metallurgical material used in iron and steel smelting, which is composed of outer iron sheet and inner alloy powder. The outer steel sheet is usually made of thin steel strip, which has a certain strength and corrosion resistance, and the inner alloy powder is configured according to the specific smelting requirements.

Commodity varieties are divided into silicon calcium core-coated wire, iron calcium core-coated wire, aluminum-calcium core-coated wire, rare earth core-coated wire, carbon core-coated wire and so on.

Standard: Diameter 9 mm, diameter 13 mm, diameter 16 mm

Production capacity: annual production of 4000 tons, can be processed according to user needs.

Quality: solid coating, no powder leakage, no crack, no line, no empty bag, no empty bag, smooth surface without oil.

Features:

• The alloy cored wire is conducive to adjusting and controlling the content of easily oxidized elements and trace elements, which can greatly fluctuate and improve the power, reduce the exercise cost, shorten the exercise time, and accurately control to 10,000.
•  The alloy core-coated wire can play a pure steel and some changes in the shape of the adulterant properties, improve the quality of molten steel
• There are two kinds of alloy core-wrapped wire: extraction type and external type.

Use of Ferro alloy cored wire

Alloy core-wire is mainly used in steelmaking, which can purify the form of steel inclusions, play a role in purifying liquid steel and partially changing the properties and forms of inclusions, improve the quality of molten steel, improve the casting state, improve the castability of molten steel, improve the service performance of steel, and significantly improve the yield of alloy, reduce alloy consumption, and reduce the cost of steelmaking.

Because it is beneficial to adjust and control the content of easily oxidized elements and trace elements, it can greatly improve the yield of alloy, reduce the smelting cost, shorten the smelting time and control the composition.

Detailed understanding of production process flow

Raw material selection

The preparation of alloy cored wire requires the selection of high-quality metal materials, commonly used materials are copper, nickel, titanium and other alloys. These materials have good electrical conductivity, corrosion resistance and plasticity, and are suitable for the preparation of high-quality alloy cored wire.

The preparation of alloy core-coated wire

1. The first step in the preparation of the alloy cored wire is to process the metal material into a fine wire and cool it by a radiator.
2. Roll the prepared fine wire into a coil, and inject protective gas between the coils to reduce the possibility of metal oxidation.
3. Put the coil into the furnace and sintering, so that the metal particles are combined into a solid, forming the main body of the alloy cored wire.

Drawing treatment

Through continuous drawing and cooling process, the diameter of the prepared alloy core-wire is gradually reduced, while its hardness and strength are enhanced, and its electrical conductivity and corrosion resistance are improved.

Polishing treatment

There will be some uneven defects on the surface of the alloy core-wire after drawing treatment, and it needs to be polished to make its surface smooth.

Final inspection and packaging

The prepared alloy core-wire needs to be inspected to check whether its size, hardness, strength and electrical conductivity are up to standard. After passing the test, it is classified and packaged to ensure its quality and application effect.

In summary, the production process of alloy cored wire includes the selection of raw materials, the preparation of alloy cored wire, drawing and polishing. These links are very critical, need great attention and careful operation, in order to prepare high-quality alloy cored wire, to provide a better choice for applications in various industries.

Classification of ferro alloy cored wire
