Calcium silicon cored wire is an out-of-furnace refining material widely used in steelmaking and casting fields. The shell is generally made of iron materials, such as thin steel strips, etc. Its function is to wrap the core layer and protect the core powder from the external environment. At the same time, it can smoothly feed the core powder into the molten steel during the wire feeding process. The core layer : The main component is calcium silicon alloy powder. The silicon content in calcium silicon alloy is usually between 55%-65%, the calcium content is between 24%-31%, and it also contains a small amount of impurity elements. Silicon and calcium have a strong affinity with elements such as oxygen and sulfur, allowing them to play an important role in deoxidation and desulfurization during the steelmaking process.

calcium silicon cored wire

calcium Silicon Cored wire has a wide range of important uses

Steelmaking field

Deoxidizer:During the steelmaking process, the molten steel contains a certain amount of oxygen, and the silicon and calcium elements in the casi cored wire have a strong affinity with oxygen. The cored wire is fed into the deep molten steel through the wire feeding device, and the casi alloy melts in the molten steel to release silicon and calcium, which can quickly react with the free oxygen in the molten steel to generate stable oxides, such as calcium oxide and silicon dioxide. These oxides will enter the slag or float up and be removed, thereby effectively reducing the oxygen content in the molten steel, improving the purity of the steel, reducing defects such as pores and inclusions in the steel, and improving the quality and performance of the steel.

Desulfurizer:Sulfur is a harmful impurity in steel, which will reduce the toughness, ductility and corrosion resistance of the steel. The calcium element in the silicon-calcium cored wire has a strong chemical affinity for sulfur. It can react with sulfur in molten steel to generate sulfides such as calcium sulfide, which enter the slag and are removed, thereby reducing the sulfur content in the steel.

Alloy additives:

Silicon and calcium elements can be accurately added to the molten steel to adjust the chemical composition of the steel to meet the specific requirements of different steel grades for silicon and calcium content, thereby improving the mechanical properties and processing properties of the steel. Silicon can improve the strength and hardness of steel, and calcium can help refine the grains, improve the toughness and welding properties of steel, etc.

Casting field

Inoculant: In cast iron production, It is used as an inoculant, which can change the growth morphology and distribution of graphite in cast iron, promote the precipitation of graphite in a fine, uniform and dispersed state, and refine the grain structure of cast iron.

Spheroidizer: For some situations where ductile iron needs to be produced, It can be used as an important component of the spheroidizer or an auxiliary spheroidizing material. It works synergistically with other spheroidizer components to crystallize graphite in cast iron into spheres, significantly improving the mechanical properties of cast iron, such as strength, toughness, ductility, etc., which are much higher than those of ordinary gray cast iron.

Ferroalloy production field

Adjusting composition: When producing other ferroalloy products, It can be used as a supplementary raw material to adjust the silicon and calcium content in the ferroalloy to achieve specific product composition standards and meet the diverse performance requirements of different downstream industries for ferroalloy products.

Improving performance: It helps to improve some properties of the produced ferroalloys, such as improving their oxidation resistance and thermal shock resistance, so that ferroalloy products can play a better role in subsequent applications (such as refractory materials, metallurgical additives, etc.), expanding their scope of application and application value.

Nonferrous metal smelting field

Deoxidation and refining: In the smelting process of some nonferrous metals (such as aluminum, magnesium, etc.), although casi cored wire is not the main deoxidation and refining material, it can also play a role in auxiliary deoxidation, impurity removal and refining under specific process requirements, which helps to improve the purity and quality of nonferrous metals and improve their performance, making them more in line with the requirements of some high-end application scenarios (such as the demand for high-quality nonferrous metal materials in the fields of aerospace, electronics industry, etc.).
