Ferro Silicon for Structural Steel
Ferro silicon is an important raw material and additive for structural steel, effectively improving the strength and toughness of structural steel, resulting in high tensile strength and toughness. In recent years, with the development of the construction industry, the market demand for structural steel has increased significantly, showing good market prospects, which has effectively boosted the ferro silicon market.
Application of Ferro Silicon in Structural Steel
Structural steel contains 0.4% to 1.75% silicon, and adding silicon can effectively enhance all aspects of structural steel performance. Ferro silicon, as a silicon-rich metallurgical material, is widely used in the production process of structural steel, serving as an important alloying agent and deoxidizer. The applications of ferro silicon in structural steel mainly include:
-
Increasing Strength of Structural Steel
The inclusion of ferro silicon adjusts the silicon content in structural steel, helping to improve its strength and hardness, increase its bendability and fatigue resistance, thus enhancing the lifespan of structural steel.
-
Improving Welding Performance of Structural Steel
Due to silicon’s excellent welding properties, structural steel with added ferro silicon exhibits good weldability, making it widely used in various construction applications and resulting in high-quality welds during the welding process.
-
Increasing Toughness of Structural Steel
Adding ferro silicon effectively enhances the toughness of structural steel, providing high impact resistance in low-temperature environments, thereby increasing the safety of structures built with structural steel.
-
Enhancing Wear Resistance
In specific types of structural steel, using ferro silicon can effectively improve wear resistance, making it suitable for projects with significant wear requirements.
Structurally steel produced using ferro silicon is widely applied in industries such as construction, machinery manufacturing, bridge construction, shipbuilding, transportation, energy, and civil engineering, making ferro silicon an essential raw material in the production process of various types of structural steel.
Grades of Ferro Silicon for Structural Steel
Due to the need to add silicon to adjust the performance of structural steel, there are strict requirements for the grades of ferro silicon. High silicon content structural steel typically uses ferro silicon 75A (Si75%), providing ample silicon. Structural steel requiring high strength and weldability uses ferro silicon 65, while those with lower silicon content requirements use ferro silicon 45 as raw material. Generally, steel mills choose different grades of ferro silicon based on the type of structural steel produced and performance requirements to ensure that product performance meets standards and design requirements.
Sustainable Development of Ferro Silicon in Structural Steel
Currently, the overall outlook for structural steel is optimistic. As the construction industry develops in various countries, the market demand for structural steel continues to grow, and the performance requirements of different industries for structural steel are becoming more stringent. As an important raw material for structural steel, ferro silicon needs continuous research and development of raw materials and production processes to meet market demands. This poses an unprecedented challenge for ferro silicon suppliers. Simultaneously, with the implementation of global environmental policies, effectively addressing environmental pollution during the ferro silicon production process is a significant task. XLS Metals conducts in-depth research on the performance of structural steel through an independent R&D laboratory, optimizing the raw materials used for ferro silicon production. With advanced production equipment and professional staff, it produces ferro silicon specifically for structural steel, providing quality and supply assurance to different users in the industry.
