Calcium Metal Powder

Calcium Metal Powder is a high-purity calcium element powder material. This product is mainly made of metallic calcium through a special process, and its appearance is silvery white or white powder. Metallic calcium powder is prone to self-heating reaction in the air, which is dangerous. Therefore, its production, storage and use must strictly comply with relevant safety regulations.

Controllable particle size
The particle size of Calcium Metal Powder is usually at the micron level, and different specifications can be provided according to demand, such as 20-120 mesh, 30-140 mesh, etc. Small and uniform powder particles can increase their surface area, making the reaction of calcium metal with smelting metal more rapid and complete. Fine-grained calcium powder can react with impurities in a shorter time, remove elements such as oxygen, sulfur, and phosphorus, and optimize the speed and effect of the smelting process.

Strong reactivity
Calcium Metal Powder has strong chemical activity and can quickly react with impurities such as oxygen, sulfur, and phosphorus in the molten metal to generate stable oxides, sulfides or phosphides, etc., which can not only remove impurities, but also avoid their negative impact on the properties of the alloy. Compared with traditional metallurgical deoxidizers, calcium metal powder can play a more efficient removal role at a lower temperature, reducing energy consumption and material loss.

Improve the fluidity and uniformity of metal liquid
After Calcium Metal Powder is added to the smelting liquid, it can improve the fluidity and uniformity of the metal melt. During the smelting and casting process, calcium powder helps stabilize the metal melt by reacting with other elements in the alloy to prevent the metal from forming pores or cracks during cooling. It can reduce crystal defects in the alloy, improve the uniformity of the metal material, and make the final product have better mechanical properties and surface quality.

Excellent desulfurization and dephosphorization performance
The calcium in Calcium Metal Powder can form stable compounds with sulfur, phosphorus and other elements in steel, and quickly remove these harmful impurities from the molten steel. This feature not only improves the quality of steel, but also improves the corrosion resistance and mechanical properties of the finished product. Especially when producing high-end steel, calcium metal powder can ensure that the steel has a lower sulfur and phosphorus content, thereby improving its corrosion resistance and processing performance.
