72/75 silicon iron steelmaking casting deoxidizer

Introduction to Ferrosilicon Ferrosilicon generally refers to iron silicon alloys made from coke, steel shavings, quartz (or silica) as raw materials and smelted in electric furnaces. It is widely used as a deoxidizer in the steel smelting industry. 1. Classification: Ferrosilicon manufacturers have received reports that ferrosilicon is classified into four types according to smelting methods: high silicon ferrosilicon (GG), ordinary ferrosilicon (PG), low aluminum ferrosilicon (DL), and high-purity ferrosilicon (GC). High purity ferrosilicon refers to ferrosilicon with low impurity element content produced by external refining method. 2. Brand designation method: The first two digits represent the classification of ferrosilicon: high silicon ferrosilicon (GG), ordinary ferrosilicon (PG), low aluminum ferrosilicon (DL), and high-purity ferrosilicon (GC); Next is the code representing ferrosilicon products, such as FeSi; Next is the content (mass fraction) indicating the lower limit o…
