Carbon-based Series

Semi-Coke – A High-Performance, Eco-Friendly Solid Fuel and Carbon Source for Metallurgy and Chemical Industries

Semi-coke, also known as low-temperature coke or clean coke, is a high-quality carbonaceous material produced through low-temperature pyrolysis of premium-grade coal or lignite. It combines high fixed carbon content, low ash, low sulfur, and low phosphorus characteristics with excellent reactivity, superior mechanical strength, and good electrical conductivity, making it a versatile and sustainable alternative to traditional coke in multiple industrial applications.

Manufactured via advanced controlled pyrolysis and quenching processes, semi‑coke exhibits uniform particle size, high porosity, stable thermal properties, and low volatile matter. It serves as an efficient reductant in ferroalloy production, a carbon raiser in steelmaking, a fuel in calcium carbide and phosphorus furnaces, and a raw material for carbon‑based products, contributing to reduced energy consumption, lower emissions, and improved process economics.

We supply semi‑coke in customized sizes (0–8 mm, 8-18 mm, 18–30 mm, etc.), tailored fixed‑carbon grades (≥82%, ≥85%), and various packaging options to meet the specific needs of ferrosilicon, silicon metal, manganese alloy, calcium carbide, and foundry industries. Supported by technical consultation and reliable logistics, we are committed to being your strategic partner in achieving cleaner, more efficient, and cost‑effective production operations.
