Calcium Silicon Granules Size 0.2-2mm

Calcium silicon granules are mainly composed of silicon, calcium and a small amount of impurities such as iron, aluminum, carbon, sulfur and phosphorus. Among them, the silicon content is generally between 55%-65%, and the calcium content is between 24%-31%. Silicon and calcium are the main effective ingredients, which play a key role in its application in steelmaking, casting and other fields, while the content of impurity elements needs to be strictly controlled to ensure the quality and performance of calcium silicon granules.

Calcium silicon granules are between 0.2-2mm in size, which is a smaller particle form. Its size is relatively uniform. This relatively consistent size distribution enables the particles to better contact and react with other substances during use. For example, in the steelmaking process, it can be more evenly distributed in the molten steel to play a role in deoxidation and desulfurization. The appearance is usually gray or gray-black particles with a relatively rough surface, which helps to increase its friction and adhesion with other substances and improve reaction efficiency.

Steelmaking deoxidizer:

During the steelmaking process, silicon and calcium in silicon-calcium granules have a strong affinity with oxygen in molten steel, and can react quickly with oxygen to remove oxygen, thereby reducing the oxygen content in steel, reducing defects such as pores and inclusions in steel, and improving the quality and performance of steel. At the same time, the deoxidation products are easy to float and discharge, making the molten steel purer.

Steelmaking alloying agent:

Silicon and calcium are added to steel as alloying elements to adjust the chemical composition of steel, improve the strength, hardness, toughness, plasticity and other mechanical properties of steel, improve the processing performance and use performance of steel, and meet the performance requirements of different steel grades.

Casting inoculant:

In casting production, calcium silicon granules can be used as inoculants, which can effectively improve the graphite morphology and distribution of cast iron, make graphite finer and more uniform, thereby improving the strength, toughness, wear resistance and other mechanical properties of cast iron parts, reducing casting defects, and improving the quality and yield of castings.

Other fields:

In addition to the metallurgical industry, calcium silicon granules are also used in some other fields. For example, in the agricultural field, it can be used as calcium silicon fertilizer for soil improvement, improving soil fertility and water and fertilizer retention capacity, and promoting the growth and development of crops; in the field of building materials, it can be used to produce cement, concrete, etc., to improve the strength and durability of materials.
