Review of China Silicon Metal Producing Areas and Capacity Commissioning Progress in 2024

Silicon slag is a by-product from the production of industrial silicon and silicon alloys. It is gaining attention for its multifunctional use in the steel and foundry industries. Its main components include silica (SiO₂, 40%-70%), alumina (Al₂O₃, 5%-20%), iron oxide (Fe₂O₃, 3%-15%), and calcium-magnesium oxides (CaO+MgO, 2%-10%). With high cost-effectiveness and environmental benefits, silica slag is becoming an important material in modern industry.

In the field of steelmaking, high carbon silicon (also known as silicon carbon alloy) plays a crucial role as an important alloy additive. Recently, with technological breakthroughs, the silicon content in high carbon silicon has been increased to 72%, bringing new opportunities and challenges to steelmaking processes. High carbon silicon can indeed partially or fully replace ferrosilicon in certain applications. Both are commonly used alloy materials, primarily in the steel industry for processes like deoxidation, alloying, and composition adjustment. The substitutability of high-carbon silicon for ferrosilicon depends on their chemical composition and the specific requirements of the application. This article delves into the applications of high carbon silicon in steelmaking and the impact of 72% silicon-content high carbon silicon on the steel industry.
