High Grade Cored Wire CaFe

 

 

The metal calcium and a certain proportion of iron powder mixed coating. The core-core wire is composed of a mixture of 25-35% calcium particles and the rest of iron powder, which is made of strip steel. Mainly used as deoxidizing and desulphurizing agent in steelmaking process;

 

1. After the addition of calcium iron wire in the steelmaking process, the formation of long strips of sulfide inclusions can be avoided, thus improving the anisotropy of steel.

 

 

 

 

2. With the help of wire feeding machine quickly input liquid steel, dissolve in the depth of liquid steel, reduce the blockage of the water mouth, play the role of deoxidation, desulfurization and inclusion.

 

3. Other components can be fine-tuned to improve the yield of metals and rare earth elements and ensure the stability of the components. Reduce the amount of valuable elements added to reduce refining costs.

The core-coated wire made by mixing calcium metal with a certain proportion of iron powder is called calcium-iron core-coated wire.

Calcium iron core-wire is composed of 25-35% calcium particles, the rest of the mixture of iron powder as the core material, with strip steel as the clad core wire, the general specifications are mainly calcium 30 and calcium 40 two kinds. Domestic and foreign iron and steel enterprises generally use calcium-iron core-coated wire for calcium treatment of low carbon, ultra-low carbon, low silicon steel and pure steel with strict requirements on the appearance and quantity of inclusions.

 

As a deoxidizer for molten steel refining, it can not only reduce the blockage of the water inlet, but also avoid the formation of long strip sulfide inclusions after adding calcium to the steel, thus improving the anisotropy of the steel. With the help of the wire feeder, the liquid steel is quickly input, melted and dissolved in the depth of the liquid steel, which plays the role of deoxidation, desulfurization and removal of inclusions, and can fine-adjust the composition, which can improve the yield of metals and rare earth elements and ensure the stability of the composition. Reduce the amount of valuable elements added to reduce refining costs.

 

It is suitable for the treatment of calcium molten steel in the process of refining outside the furnace. Φ13mm suitable for small and medium-sized electric furnace use strong versatility, Φ16mm suitable for large electric furnace use.

 

 

 

The general data for steelmaking core-wire is the weight of the strip per meter and the weight of the powder per meter. The thickness of the ball core wire is usually 0.6mm, and the weight of the strip is always 170g/m weight, and different alloys will have different data. For example, the CaSi6030 and CaSi5528 core wires weigh 230g/m, while the CaFe core wires weigh 215g/mm and the carbon core wires weigh about 150g/m.
