65 low alumina ferrosilicon block

Low-alumina ferrosilicon: Meeting the high-end demands of clean steel smelting. With the continuous improvement of requirements for the purity, performance stability and service life of Steel in high-end manufacturing industries (such as automobiles, aerospace, precision instruments and electrical products), the smelting of Clean Steel has become crucial. Non-metallic inclusions in steel (especially Al2O3 clusters) are the main source of hazard. The aluminium (Al) content in traditional ferrosilicon (typically 1-2%) is an important source of impurity aluminium. Low Aluminum Ferrosilicon emerged specifically to meet this high-end demand. Features: Core indicator: The aluminum (Al) content is much lower than that of ordinary ferrosilicon. According to the user's requirements, it can be classified into different grades, such as Al < 1.0%, Al < 0.5%, Al < 0.2%, and even Al < 0.1% (ultra-low aluminum). The production process has higher requirements: low-alumina raw materials (s…
