Silicon calcium alloy is a binary alloy of calcium and silicon. This type of alloy is used in a wide variety of applications. It has a strong deoxidation capability, allowing it to be effective in many steel-making processes. In addition, it is an important inoculant for cast iron, improving its quality and performance.
The market for silicon calcium alloy has been growing. This is due to its use in high-quality steel production. Silicon calcium can improve the plasticity and ductility of steel, while its deoxidation ability is excellent. In addition, the alloy can also be an effective warming agent. When mixed with a certain amount of iron, it can help control the distribution of sulfide inclusions, minimizing the likelihood of chain-type inclusions.
Silicon calcium is a binary alloy that contains two thirds silicon and one third calcium. It can be produced in two different ways. First, it can be produced in an electric furnace. Alternatively, it can be made using concentrated solar energy. Regardless of the process, it is an energy-intensive one. Production costs are 40-70% based on electricity.
Ferrosilicon is a form of silicon calcium that contains varying levels of impurities. Some of these impurities include sulfur, carbon, nitrogen, and chlorine. The specific weight of ferrosilicon is lower than that of the calcium silicon alloy, but its recovery is higher. Therefore, it can be easily separated.
Silicon calcium alloy is a common component of converters and ladles. It is often used in the steel industry to increase the impact toughness and processability of steel. Depending on the application, the alloy is able to deoxidize aluminum. A further application for the alloy is as a denaturant for calcium additives. As a result, the use of the alloy in the steelmaking process is widespread.
There are many types of silicon calcium alloy. These include low, medium, and high specification products. The alloy is available in a powder or lump form. While the former is easier to handle, the latter is more stable. Typically, the products are packaged with a ton bag, but they can be shipped in bulk according to the user's needs.
The price of the alloy depends on the quantity and the cost of its production. Since it is an energy-intensive product, the price is also affected. However, technological innovation can continue to optimize its performance.
Silicon calcium is available in two forms - powder and lump. The former is produced by an intermediate frequency furnace, while the latter is produced in an electric furnace. Both of these products can be easily manufactured with the aid of a flexibly controlled output.
Silicon calcium can be produced in both high-carbon and low-carbon forms. High-carbon ferrosilicon can be produced by an electric furnace or by mixing it with lime. Low-carbon products can be manufactured in a medium-frequency furnace, which has a relatively low cost of production.
The key players operating in the calcium silicon alloy industry are Ningxia Darshan Silicon Industry Co., Ltd. (Ningxia), Wanhua Metal Company (Wanhua), CNMI Silicon Industry (CNMI), Shanghai Jiebo Industrial Group (Shanghai), and American Elements.
