Once considered mere industrial waste requiring disposal, ferrosilicon slag has undergone a remarkable transformation. Today, driven by the global push toward a circular economy and green metallurgy, this smelting by-product is recognized as a valuable secondary raw material. No longer just an envir

Silicon slag is a valuable industrial by-product generated during the smelting of metallic silicon. Primarily composed of silicon dioxide (SiO₂) and carbon (C), with minimal metallic impurities, it has become a widely adopted, economical material across multiple sectors—especially in metallurgical a

Ferrosilicon is a fundamental ferroalloy primarily composed of iron and silicon, with tightly controlled low levels of aluminum, calcium, and carbon. Among its various grades, FeSi75 (72%-78% Si) and FeSi72 (70%-75% Si) are the most widely used in global industry. Renowned for its high melting point

Carbon cored wire is a purpose-engineered material designed specifically for the steel industry. It consists of precisely sized, high-purity carbon raiser particles—essential for adjusting the carbon content in molten steel—encapsulated within a robust steel strip. This innovative delivery system en

Ferrosilicon slag, a valuable by-product from ferrosilicon alloy smelting, transforms into a versatile industrial resource through precise processing. At Hongshun Ferroalloy, we implement controlled cooling, solidification, crushing, and classification to ensure our slag delivers excellent chemical

Ferromanganese is categorized by carbon content into high carbon ferromanganese (approx. 7% C), medium carbon ferromanganese (approx. 1.0–2.0% C), and low carbon ferromanganese (max. 1.0% C). Among these, low carbon ferromanganese delivers higher economic value and is widely used across the steelmak
