Silicon Metal Lump | High Purity Si ≥99% & Best Price
We crush the freshly smelted silicon metal and process it into lumps sized 10mm–50mm, 50mm–80mm, and 80mm–120mm. The processed silicon metal have a uniform grain size and a gray appearance with a metallic luster, which makes them easy to package and store, using ton bags for packaging. Metallurgical grade silicon metal lumps are widely used in processes such as steelmaking, metallurgy, and aluminum smelting, with the largest consumption occurring in aluminum smelting. They effectively promote the melting of aluminum, enhance the flowability of molten aluminum, and improve the castability of aluminum during casting. In recent years, as the market has expanded, the demand for silicon metal for aluminum has shown an upward trend, making it an important additive for aluminum.
Processing Technology of Silicon Metal Lumps
We process silicon metal according to user requirements for different grades of silicon metal. The commonly used silicon metal primarily includes 421 grade, 441 grade , and 553 grade . First, we need to manually select high purity silicon metal and take samples. After testing in a professional laboratory to ensure compliance with requirements, the material is manually crushed. The manually crushed silicon metal then undergoes further processing through more specialized crushing equipment and is screened to ensure that the processed silicon metal lumps have a uniform particle size. The processed silicon metal lumps are then transported to the packaging area via a conveyor belt, where they are uniformly packaged and shipped using tonnage bags.
Uses of Silicon Metal Lumps
Silicon metal lumps are widely used in the production of high-quality steel and various aluminum profiles. Pure silicon metal lumps, after purification, are applied in photovoltaic, semiconductor, and silicon products.
-
Steel Making: Silicon metal lumps act as an efficient deoxidizer, effectively removing oxygen from molten steel, reducing oxides and inclusions, which helps achieve a pure state of the steel and enhances its quality.
-
Aluminum Products: Gray solid silicon metal lumps improve the flow performance of molten aluminum and the castability of aluminum, maintaining stable furnace temperatures, increasing the yield of aluminum products, and boosting production.
-
Metallurgy: During the metallurgical process, it is necessary to reduce the elements in raw materials. Silicon metal lumps serve as excellent reducing agents, enhancing the efficiency of the metallurgical process.
-
Purified Silicon Metal Lumps: As the applications of silicon continue to expand in various industries, chemical grade silicon metal can serve as important raw materials for photovoltaic, semiconductor, silicone rubber, silicone oil, and other silicon products.
Grades of Silicon Metal Lumps
The silicon metal lumps we produce use high purity silicon metal with a Si content of ≥99% as raw material for processing, and they are tested by third-party organizations such as IOS, BV, and SGS. By combining manual screening with mechanical processing techniques, we can convert different grades of silicon metal into silicon metal lumps as required by the user.
