Silicon calcium alloy cored wire is a new type of off-furnace refined material commonly used in the steel and foundry industries. It usually uses low-carbon steel strips. This type of steel strip has good ductility and toughness, can tightly wrap the internal alloy powder during processing, and will not cause excessive carbon addition to the molten steel under high temperature conditions. Silicon calcium alloy powder is a powdered substance made by crushing and grinding silicon calcium alloy. Si and Ca are the main elements in its composition, and it also contains a small amount of Fe, Al and other elements. The size of CaSi alloy powder needs to be strictly controlled to ensure that it can dissolve and react quickly and evenly in the molten steel.

Performance characteristics

Uniform composition:

Due to the precise control of the proportion and mixing of the alloy powder during the production process, the calcium silicon alloy composition in each section of the cored wire is uniform, thus ensuring the stability of the treatment effect on molten steel or molten iron during use.

Efficient reaction:

It is tightly wrapped by the steel strip. After being added to the molten steel or molten iron, as the steel strip gradually melts, the alloy powder can quickly contact and react with the molten metal, which improves the absorption rate of the alloy elements and reduces the burning loss of the alloy elements.

Strong deoxidation and desulfurization ability:

Ca and Si in calcium silicon alloy are strong deoxidizers, and Ca also has good desulfurization ability. When the CaSi alloy cored wire is added to the molten metal, it can quickly reduce the oxygen and sulfur content in the molten metal and effectively improve the purity of the metal.

Application advantages

Improve product quality

Effective deoxidation, desulfurization and precise control of alloy composition can significantly improve the quality of steel and castings, reduce impurities and defects, and improve the qualified rate and performance indicators of products.

Reduce production costs

Compared with traditional alloy addition methods, the alloy element absorption rate is high, which reduces alloy waste and reduces production costs. At the same time, it improves production efficiency and reduces rework and scrapping caused by product quality problems.

Easy operation

The alloy cored wire is accurately added to the molten metal through the wire feeding machine. The operation process is simple and controllable, which is convenient for realizing automated production and improving the stability and reliability of the production process.
