In large-scale industrial applications, particle sizing determines reaction speed, safety, and efficiency. Small granules react too violently for certain systems, which is why heavy steel mills and large industrial acetylene stations specifically rely on 80-120mm calcium carbide. These large, uniform chunks ensure a controlled, prolonged chemical reaction, reducing gas spikes and protecting your processing equipment.
As a direct Chinese manufacturer operating large-scale electric-arc furnaces, we produce tightly screened, high-purity 80-120mm calcium carbide lumps engineered to withstand long-distance maritime transport without premature crumbling.

The 80-120mm calcium carbide mesh size is not a general-purpose product; it is a highly specialized industrial raw material preferred for two core applications:
Steelmaking Deoxidation & Desulfurization: In modern Electric Arc Furnaces (EAF) and ladle metallurgy stations, smaller carbide sizes burn off instantly on the slag surface. The 80-120mm large chunks successfully penetrate the slag layer, reacting deeply within the molten steel to capture sulfur and optimize slag foaming safely.
Continuous Acetylene Generation plants: Industrial gas stations utilizing hopper-fed generators require slow, steady gas release. Large lumps dissolve at a predictable, uniform rate, preventing dangerous sudden pressure overloads inside the generator columns and drastically reducing limestone dust blockages.
Buying large-size hazardous chemicals across the ocean comes with unique challenges. We have structured our factory output to eliminate your three primary sourcing risks:
The Problem: Low-quality carbide lumps can easily fracture into small dust particles during rough sea voyages, arriving at your warehouse as a high-risk powder instead of large stones.
Our Solution: Our 80-120mm chunks feature an ultra-dense crystalline matrix formed by slow-cooling high-grade lime and coke raw materials. This structural integrity minimizes internal friction inside the drums, ensuring your cargo arrives in its original large-stone form.
The Problem: Humidity inside shipping containers can degrade large carbide stones into lime powder, drastically lowering your actual gas yield on arrival.
Our Solution: We pack our 80-120mm calcium carbide in UN-certified heavy-gauge steel drums. Every drum is fully flushed with bone-dry nitrogen gas before mechanical crimping. This creates a zero-oxygen, moisture-free storage condition that keeps the chemical stable for up to 24 months.
The Problem: Shipping lines routinely reject Class 4.3 cargo, leading to production stoppages while you wait for a vessel slot.
Our Solution: Located in proximity to Tianjin Port, we maintain year-round contractual dangerous goods booking priority with major ocean carriers. We prepare complete, flawless export documentation (including bilingual SDS, Dangerous Goods Certificates, and COA) to ensure seamless customs clearance.
We provide two industrial packing standards tailored to your yard's mechanical capabilities:
50KG Heavy Tinplate Drums: 450 drums per 20ft container (22.5 Net Metric Tons). Highly recommended for plants that move inventory manually or via small forklifts.
100KG Bulk Industrial Drums: 225 drums per 20ft container (22.5 Net Metric Tons). Ideal for large metallurgy yards utilizing overhead magnetic cranes or automated drum-tipping hoppers.
Both packaging variants can be customized in terms of outer drum paint color (RAL standards) and multi-lingual safety stenciling (English, French, Spanish, or Portuguese) at no additional charge.
Stop dealing with multi-tier trading companies that do not understand hazardous logistics. Partner directly with a professional Chinese manufacturer capable of executing reliable, continuous shipments.
We regularly supply heavy steel mills and gas networks across West Africa, South America, and Southeast Asia. Let our technical sales team draft a complete loading plan and ocean freight quotation for your destination port.
