Calcium Silicon Cored Wire knowledge
It is suitable for deoxidation and desulfurization in steelmaking. It can improve the properties of steel, and improve the plasticity, impact toughness, and fluidity of molten steel. It also has the characteristics of directly entering the molten steel for melting and uniform distribution.
With the development of the steelmaking industry, the substantial growth of high-quality alloy steel and steel varieties, the gradual increase of continuous casting ratio, and the continuous improvement of out-of-furnace refining technology have contributed to the successful development of wire feeding technology. The use of wire-feeding technology has greater advantages than powder spraying and the direct addition of alloy blocks.
When in use, the cored wire is continuously fed into the ladle through the wire feeding machine. When the sheath of the calcium silicate cored wire entering the ladle melts, the core powder layer is exposed and directly contacts the molten steel for chemical reaction, and passes through The dynamic effect of argon gas stirring enables it to effectively achieve the purpose of deoxidation, desulfurization, and removal of inclusions to improve the quality and performance of steel.
`
It can be seen that for calcium silicate cored wire to effectively purify molten steel, two conditions must be met:
1) The active ingredients in the core powder layer must be able to immerse into every corner of the molten steel;
2) the active ingredients in the core powder layer It has sufficient ability to capture oxygen and sulfur atoms.
In the existing technology, calcium is a commonly used core powder material. Although it is a strong deoxidizer, its specific gravity is relatively light, its melting point is relatively low, and it is easy to generate bubbles at high temperatures. Therefore, compared with silicon Calcium cored wire simply uses metallic calcium as the core powder layer of the cored wire, which will cause the cored wire to start burning as soon as it is sent into the refining furnace.
However, if the cored wire does not enter below the middle of the molten steel, it will not reach the required height. For an ideal purification effect, even if measures such as high-temperature-resistant wrapping materials and quick insertion are used, it cannot completely hinder its combustion. The core powder layer cannot achieve the ideal purification effect when burned under such working conditions, and it will also cause high prices. Higher waste of calcium resources.
