Carbon Additive Products & Recarburizers
Premium carbon additives and recarburizers for steelmaking, foundry, and metallurgical applications—manufactured under ISO 9001 quality management, batch-tested, and supplied to buyers in 50+ countries.
Every Grade Engineered for Your Furnace
We produce seven distinct carbon and alloy product families, each optimized for specific metallurgical applications. Whether you operate an electric arc furnace processing 200 tons per heat or an induction foundry pouring precision castings, we manufacture to the chemistry, sizing, and packaging specifications that your process demands — backed by lot-specific Certificates of Analysis from our in-house laboratory.
Calcined Anthracite Coal
The workhorse recarburizer of the global steel industry. Produced from Ningxia's Taixi anthracite through gas calcination at 1,200°C+, our CAC delivers fixed carbon of 90–95% with the low ash and sulfur profiles that EAF and ladle furnace operators require for predictable carbon pickup.
- Easy molten bath introduction
- High carbon solubility rate
- Consistent performance quality
Graphite Petroleum Coke
The premium choice for applications demanding ultra-low sulfur and maximum carbon purity. Graphitized at 2,500–3,000°C, our GPC achieves FC ≥98.5% with sulfur as low as 0.03% — the benchmark for ductile iron foundries and specialty steel producers who cannot tolerate sulfur-related quality defects.
- High fixed carbon content: ≥98.5%
- Low sulfur: ≤0.05%
- Low ash: ≤0.5%
Semi Coke
Produced through low-temperature carbonization at 500–750°C, Semi Coke offers an economical fixed carbon source (≥84%) with the specific electrical resistance properties essential for submerged arc furnace operations in ferroalloy production.
- High fixed carbon content: ≥84%
- Low sulfur content: ≤0.4%
- Low ash content: ≤9%
Calcined Petroleum Coke
Calcined at 1,200–1,400°C from select green petroleum coke, our CPC delivers FC ≥98% with uniform particle distribution — bridging the gap between economical anthracite-based recarburizers and premium GPC for applications where cost-performance balance is critical.
- High fixed carbon content: ≥98%
- Low sulfur content: ≤0.5%
- Low moisture: ≤0.5%
Silicon Carbide
A metallurgical multitool: our Silicon Carbide simultaneously contributes carbon and silicon to the melt, provides powerful deoxidation, and generates exothermic energy that reduces electrical consumption in EAF steelmaking by 10–15 kWh per ton of steel.
- Extremely hard material
- Efficient heat dissipation
- Chemically stable in environments
Ferro Silicon
The foundational deoxidizer and alloying agent for steelmaking worldwide. Our FeSi is produced in Ningxia's submerged arc furnaces, available in 72% and 75% silicon grades, with the low aluminum and calcium content that specialty steel producers demand.
- Silicon content ranges from 15% to 90%
- Available in various grades and forms
- Improves mechanical properties
Silicon Manganese
A dual-function ferroalloy delivering simultaneous deoxidation and manganese alloying in a single addition. Our SiMn combines 65–70% Mn with 15–20% Si, enabling steel producers to achieve target chemistry with fewer charge additions and tighter composition control.
- High Manganese Content
- Contains 10-20% silicon
- Low Carbon Levels
