Alloy Cored Wire

The cored wire is also called alloy cored wire. It is to crush various additives (Deoxidizer, desulfurized, modifier, alloy, etc.) that need to be added in molten steel or molten iron into certain particle sizes, and then wrap them with cold-rolled low-carbon steel strips to make composite long wires of various diameters. It is often packed in a steel cage in the form of horizontal packaging. The hot-selling alloy cored wire products produced by ZX mainly include pure calcium cored wire, calcium silicate cored wire, iron calcium cored wire, etc.

Use of Alloy Cored Wire

With the continuous development of the steelmaking industry, the output of high-quality alloy steel and various steel has increased substantially, the continuous casting ratio has gradually increased, and the continuous improvement of the refining technology outside the furnace has promoted the successful development of alloy cored wire technology. Judging from the production data for many years, the method of feeding the alloy cored wire into the molten steel through the wire feeding equipment has greater advantages than the method of powder spraying and directly adding the alloy block.

Use of Alloy Cored Wire

The alloy cored wire technology is an advanced method of refining outside the furnace, which is suitable for steelmaking and foundry industries. The use of alloy cored wire can more effectively add smelting materials to molten steel or molten iron in the steelmaking or casting process, and the alloy cored wire can be inserted into the ideal position through professional wire feeding equipment. When the skin of the alloy cored wire is melted, the alloy core can be fully dissolved in the ideal position and a chemical reaction can occur. This method can effectively avoid unnecessary reactions between the alloy, air and slag, thereby increasing the absorption rate of smelting materials. Alloy cored wires are widely used as deoxidizers, desulfurizers and alloy additives in steelmaking and casting processes, which can change the shape of molten steel inclusions and effectively improve the quality of steelmaking casting products.

Advantages of ZX Alloy Cored Wire

  • ZX alloy cored wire has the advantages of uniform powder feeding, regular assembly size, and low wire breakage rate;
  • The ZX alloy cored wire is firmly wrapped and sewed, without powder leakage, slotting, virtual package, empty package, the surface of the wire is smooth, and the weight deviation of the powder core is generally 5g/m;
  • The alloy cored wire is divided into two types: internal drawing type and external release type. The mechanical equipment required for feeding the wire is simple and reliable, and it occupies a small area. In particular, the internally drawn cored wire is more suitable for use in narrow venues;
  • The use of alloy cored wire can play the role of pure molten steel and partially change the nature and shape of inclusions, which can improve the quality of molten steel and improve the casting state;
  • ZX alloy cored wire is beneficial to adjust and control the content of easily oxidizable elements and trace elements, greatly increase the alloy yield, reduce the smelting cost, and accurately control the composition.

1. Raw material preparation

Steel strip, as the outer skin of the alloy cored wire, is made of cold-rolled low carbon steel. The width of the steel strip varies according to the diameter of the alloy cored wire (9-16mm). The thickness of the steel strip is generally between 0.2-1.0mm.

Inner package raw materials. According to the type of cored wire, the alloy raw material that needs to be wrapped in the skin is crushed into the required particle size. Such as calcium powder in pure calcium cored wire, silicon calcium powder in calcium silicate cored wire, carbon powder in carbon cored wire, etc.

2. Raw material mixing

The raw materials needed in the alloy cored wire are uniformly mixed according to a certain ratio.

3. Crimping and biting synthetic forming

In the production process of alloy cored wire, the raw materials and steel strips are formed into a shape by crimping and biting synthetic in the cored wire machine.

4. Wound into a coil

The formed alloy cored wire is wound into coils in batches, and then the finished alloy cored wire is obtained.
