65 low alumina ferrosilicon block

Low aluminum ferrosilicon is a high-end ferroalloy product that meets the requirements of clean steel smelting. With the continuous improvement of steel purity, performance stability, and service life requirements in industries such as automotive, aerospace, and precision instruments, reducing non-metallic inclusions (especially Al ₂ O3 clusters) in steel has become a key challenge. The aluminum content of traditional ferrosilicon is usually 1-2%, which is an important source of impurity aluminum in steel. However, low aluminum ferrosilicon significantly improves the cleanliness of steel by strictly controlling the aluminum content.Product Features●Low aluminum index: The aluminum content is significantly lower than that of ordinary ferrosilicon, and can be divided into different grades such as Al<1.0%,<0.5%,<0.2%, and even<0.1% (ultra-low aluminum).●High process requirements: Low alumina raw materials (such as low alumina silica and low alumina coke) need to be selected,…
