Cored wire production

The core-spinning technology is a kind of refining method that has been developed in recent years and is widely used in the technology of modern steel-making feeding wire (adding core wire to steelmaking furnace). Many core wire manufacturers are now promoting this product.

Cored wire

Cored wire producer can make different core wires according to user requirements. Such as silicon calcium core wire, silicon manganese calcium wire, silicon calcium calcium wire, aluminum calcium wire, calcium iron wire, pure calcium wire and so on.

Cored wire manufacturing process

The alloy cored wire is a composite material. The alloy core wire is used to crush various additives (deoxidizer, desulfurizer, modifier, alloy, etc.) to be added into molten steel or molten iron into a certain particle size, and then use cold-rolled low-carbon steel strip to package it as A composite material of any length.

The core wire consists of a steel cladding coated with alloy powder. It is wound on a reel and produces a coil weight of 100-3000 kg. The diameter of the wire is 3-18mm.

The core wire is compact and the powder material is evenly mixed. The weight of the powder can be calculated by the unit length (meter).

Cored wire application

Cored wire advantages

The core wire injection technology has replaced the injection method of single shot refractory gun powder and proved to be an indispensable method in the secondary metallurgical process.

  • High speed continuous
  • Meet the increasing requirements for chemical elements in casting
  • Processing time is shorter and more accurate
  • Very good repeatability.

What is cored wire used for

The cored wire is widely used in steelmaking technology.

1. It is beneficial to adjust and control the content of easily oxidizable elements and trace elements, and can greatly increase the alloy yield, reduce the smelting cost, shorten the smelting time, and accurately control the composition.

2. It can play a role in making the molten steel pure and partial change the nature and shape of the inclusions, improve the quality of the molten steel, and improve the casting state.
