Calcium Silicon Cored Wire (CaSi Wire)

CaSi cored wire is made of calcium silicon powder. In detail, the CaSi cored wire is composed of calcium silicon particles as the core material, made of strip steel as the cover.

Calcium silicon alloy is a compound alloy made up of elements silicon, calcium, and iron, is an ideal compound deoxidizer, and desulfurization agent.

Calcium Iron Cored Wire

What is Casi Wire Used For?

At present calcium alloy can be used instead of aluminum for final deoxidation, and is applied to high-quality steel, special steel, and special alloys production. Such as rail and low carbon steel, stainless steel, steel and nickel base alloy, titanium alloy, and other special alloy.
  Calcium Silicon Cored Wire,casi cored wire, and calcium silicon alloy cored wire is made from calcium silicon powder.

Cored wire is used for steelmaking. It can purify the liquid steel, change the impurities shapes, improve the castability of iron and steel, improve the using performance of steel, and significantly enhance the ferroalloy yield rate, reduce alloy consumption as well as the cost of steelmaking in consequences to get remarkable economic benefits.

Features of Calcium Silicon Cored Wire

  1. The metal powder is firm in the steel belt, not hollow. And the wire is seamless, and will not be broken.

2. Being propitious to adjust and control the active metal and the content of microelement.

3. Keep stable of the alloy performance function, reducing steelmaking costs.

4. Changing the inclusion form to improve the mechanical property.

5. It is used by injection way. Facilitate the operation and reduce the operation cost.

In the production of cast iron, it is mainly used in apricot gold, desulfurization, spheroidization, creeping treatment, and inoculation treatment of cast iron. The standard of the cored wire varies from process to process.

1. Reasonably adjust the feeding speed.

The feeding speed has a great influence on the Ca absorption rate. Too fast and too slow will result in a decrease in absorption rate.

The core wire begins to melt when it is fed to a certain depth. The depth should be such that the molten and dispersed calcium bubbles are subjected to a large hydrostatic pressure. This causes it to be completely consumed as much as possible before it floats to the molten steel.

A suitable feed speed can increase the yield of calcium.

<1> If the speed is too fast.

On the one hand, the molten steel is violently tumbling due to the large amount of calcium vapor generated locally, and a large amount of calcium vapor is directly volatilized into the air.

On the other hand, calcium vapor is too late to dissolve and floats a lot, thereby reducing its yield.

<2> If the speed is too slow.

Too slow a speed will result in insufficient feed depth. Before it is completely dissolved in the molten steel, it floats up to the molten steel surface and is wasted.

2. Correctly select the feeding position.

The feeding position also has a great influence on the yield of calcium. The solid core calcium feed point should be chosen at the center of the molten steel flow. Try to stay away from the argon-blowing circle.

In this way, no matter whether Ca enters the molten steel in a gaseous state or in a liquid state, it will be forced to descend under the action of the descending flow. Thereby extending its residence time in the molten steel, so that it is fully absorbed by the molten steel.

The calcium silicon cored wire is a product of improved quality in steel making. With the development of society, the types of cored wires are increasing. Pay attention to details when selecting products to avoid buying inferior products.
