Purchase High-Quality Ferro Silicon 75 Lumps
Ferro silicon 75 lumps are widely used in steelmaking, mainly for deoxidation. High-quality ferro silicon 75 lumps can maximize the deoxidation of molten steel, reducing the number of oxides in the steel and allowing impurities to float to the surface. This makes it easier for workers to handle the slag, greatly improving the purity of the steel.
When purchasing ferro silicon 75 lumps, it's important to assess their quality by examining their appearance, composition, physical properties, and other indicators. High-quality grey ferro silicon 75 lumps should be dark gray with a bright, uniform metallic luster. lumps that are uneven in color or dull in appearance may indicate lower quality. The surface should be smooth and free of cracks, with no oxidation. lumps with rough surfaces, numerous cracks, or signs of oxidation may indicate poor quality.
The main component of ferro silicon 75 lumps is silicon, and its content directly affects the quality of the lumps. High-quality ferro silicon lumps should meet national standards for silicon content, with low levels of impurities. The content of impurity elements such as calcium oxide and magnesium oxide in high-quality ferro silicon 75 lumps should be low. Typically, the content of calcium oxide and magnesium oxide in ferro silicon should be less than 1%; otherwise, it may increase the amount of slag during steelmaking and cause erosion at the iron outlet, impacting the quality of ferro silicon lumps.
The density and hardness of ferro silicon 75 lumps are important indicators of their physical properties. Testing the density and hardness of ferro silicon lumps can provide insight into their mechanical performance. The particle size distribution has a significant impact on the application performance of ferro silicon lumps. High-quality ferro silicon lumps should have a uniform particle size distribution that meets production requirements. Particle size analysis can help optimize the smelting process and improve production efficiency.
