Description

Introduction of High Carbon Silicon

High-carbon silicon, also called silicon-carbon alloy, is a new alloy used in converters. It is a by-product of the production process of metallic silicon or silicon metal. The main components of high carbon silicon are silicon and carbon. The silicon content is generally above 55%, while the carbon content is above 15%. Other components include silicon dioxide, phosphorus, and sulfur. Other contents include: silica, phosphorus, sulfur, etc. High carbon silicon is a new type of metallurgical material that can replace traditional ferrosilicon, silicon carbide and carburizing agents. It has high thermal stability and chemical stability, which can reduce the amount of deoxidizer, thereby reducing costs, while improving the quality of steel, reduce the waste of resources and maximize the utilization of resources. Therefore, the emergence of high-carbon silicon is not only of great significance to the metallurgical industry, but also provides higher-quality steel for all walks of life.

Production Process Of High Carbon Silicon

High carbon silicon is a ferrosilicon alloy with a special preparation method that has a wide range of uses. It is mainly composed of ferrosilicon, coal tar, charcoal and some starting materials. The preparation of high-carbon silicon requires strict technological processes and high-temperature reaction conditions to form. The main raw materials of high-carbon silicon are quartz, coke and charcoal. Quartz is silica extracted from ore or yellow sand, while coke and charcoal are prepared by carbonizing coal under specific process conditions. When preparing high-carbon silicon, these raw materials must go through complex processes such as crushing, smelting, and cooling to form the required high-carbon ferrosilicon alloy. The preparation process of high-carbon silicon requires the use of high-temperature reaction conditions, usually in a high-temperature furnace. In the furnace, raw materials such as quartz, coke and charcoal are injected together and react at high temperatures. Over time, the reactants will gradually crystallize into high-carbon ferrosilicon alloy.

Characteristics Of High Carbon Silicon:

Experiments and production applications have shown that the use of high-carbon silicon deoxidation alloy technology has greatly reduced the cost per ton of steel, created considerable economic benefits, and improved the market competitiveness of steel.

Irreplaceable And Important Role In The Metallurgical Industry

As a high-quality metallurgical material, high-carbon silicon plays an irreplaceable and important role in the metallurgical industry. It is an alloy containing a large amount of carbon and silicon elements. It is mainly obtained from high-purity silicon ore and coke used for smelting through high-temperature reduction reactions. Let's discuss the main role of high-carbon silicon in the metallurgical industry.

First, high-carbon silicon can significantly improve the hardness and wear resistance of the material, making it more durable. It can be added to a variety of different metal alloys to increase their hardness and strength. Therefore, high-carbon silicon is widely used in manufacturing automobiles, construction and machinery. Especially in the steel industry, high-carbon silicon can also make steel higher hardness and wear resistance, thereby improving the service life and reliability of steel.

Secondly, high-carbon silicon can increase the brittleness temperature of the metal, making it more resistant to high temperatures. This is because high-carbon silicon can be combined with other metallic elements to form high-temperature alloys, making them resistant to corrosion and other damage at high temperatures. High-temperature alloys are widely used in petrochemical, aerospace, shipbuilding and other fields under high-temperature environments, making great contributions to the development of these industries.

In addition, high carbon silicon can also be used as a metallurgical treatment agent. It can be added to the charge to help eliminate impurities and metal inclusions, thereby improving the quality and purity of the metal. High-carbon silicon can also be used as an oxidant to help melt and refine metals and improve production efficiency. Therefore, high-carbon silicon is widely used in metallurgical processes such as steelmaking, casting and metal processing.

As can be seen from the above, high carbon silicon plays a very important role in metallurgy, especially steelmaking. It can improve the performance of steel and increase the quality and service life of steel. Today, ferroalloy materials are more expensive. As a new type of metallurgical material, silicon-carbon alloy is favored by many manufacturers because it is cheaper than traditional metallurgical materials. High-carbon silicon can replace expensive metallurgical materials such as ferrosilicon and achieve unexpected results. The effect is satisfactory, so using silicon-carbon alloy can save manufacturers costs and increase profits.

The particle size of silicon carbon alloy: natural block, 10-100mm, 10-50mm or according to customer requirements.
