Steel producers across the globe are increasingly turning to high-purity calcium carbide as a cost-effective and reliable solution for sulfur removal—a critical step in enhancing steel quality and reducing production waste. At Longwei Chemical, our carbonated calcium carbide has been tested in real-world applications at over 12 major steel plants in Inner Mongolia, delivering consistent results that speak louder than claims.
| Application Area | Average Sulfur Reduction | Customer Satisfaction (Survey) |
|---|---|---|
| Basic Oxygen Furnace (BOF) | ≥ 0.015% → ≤ 0.005% | 94% (n=37) |
| Electric Arc Furnace (EAF) | ≥ 0.012% → ≤ 0.004% | 91% (n=29) |
In one case study from an integrated steel mill in Ordos, Inner Mongolia, switching to Longwei’s ultra-pure calcium carbide reduced slag volume by 18% and improved yield consistency across 3 consecutive months—leading to a measurable ROI within just 6 weeks.
Our facility in Ordos benefits from proximity to raw materials like coke and limestone—key inputs for producing industrial-grade calcium carbide. With a monthly output capacity of up to 8,000 metric tons, we maintain stable supply even during peak demand periods. This ensures that your production schedule stays on track—not delayed by logistics bottlenecks.
Quality control is embedded in every stage—from incoming material inspection to final batch testing using ISO-certified labs. Each shipment includes a Certificate of Analysis (CoA) with traceable purity levels above 95%, ensuring compliance with international standards such as ASTM E1234 and GB/T 10665-2013.
What sets Longwei apart isn’t just its role as a de-sulfurizer—it’s also a key component in generating acetylene gas for welding and cutting operations. In a pilot project involving 50+ construction sites in northern China, our product delivered a 97% success rate in consistent acetylene generation, minimizing downtime caused by inconsistent gas flow.
“We’ve seen fewer rejections due to sulfur-related defects,” says Li Wei, Head of Quality at a Tier-1 Chinese steel producer. “And when we switched suppliers last year, the difference wasn’t subtle—it was immediate.”
