Engineered for heavy-duty continuous generators and deep ladle steel refining. Ultra-dense crystal matrix designed to survive long-distance ocean transport without crumbling.
Specialized heavy industrial applications require controlled chemical kinetics that smaller stones simply cannot provide. The 80–120mm extra-large lump size is engineered for heavy-duty stability:
Heavy Steel Slag Penetration: In modern Electric Arc Furnaces (EAF) and Ladle Metallurgy Furnaces (LMF), smaller stones burn away on the slag surface. 80–120mm heavy lumps successfully sink through the thick slag layer, reacting deep inside the molten steel.
Continuous Multi-Day Acetylene Production: Large continuous generators running 24/7 require steady, predictable dissolution over hours, eliminating frequent hopper reloading and dangerous gas surges.
Zero Dust Hazard & Zero Material Loss: Oversized lumps completely eliminate fine chemical dust, preventing worker respiratory hazards and atmospheric degradation during vessel transfer.
Our 80–120mm lumps are produced from high-grade lime and coke, slow-cooled in Inner Mongolia electric arc furnaces to create an ultra-dense crystalline structure. This guarantees high mechanical strength during rough ocean transit.

Because 80–120mm lumps are typically purchased in massive multi-container volumes for remote mining or heavy steel yards, long-term storage integrity is vital:
Heavy-Gauge Reinforced Drums: Extra-thick tinplate drum walls engineered to resist internal impact from large heavy stones during high-seas rolling.
24-Month Weatherproof Storage: Double-sealed nitrogen purge ensures zero pressure buildup or oxidation, even in hot and high-humidity tropical ports.

Precautions
Inspection upon Receipt
-Inspect drums upon receipt, paying attention to moisture (e.g., snow, ice shouldbe removed before storage).
-Check for signs of swelling, heat, or mechanical damage.
Handling Hot Drums
-If a drum is hot, do not cool it with water, and do not move the drum until it hascooled completely.
-The area should be cordoned off, and entry restricted until the drum cools.
Opening the Drum
-Use non-sparking tools (e.g,, brass hammer) to open the drum in a designatedarea.
-Ensure drums are opened only immediately before the calcium carbide is requiredfor use.
Personal ProtectiveEquipment
-Wear personal protective equipment (PpE), including gloves, helmets, and faceshields when opening drums and handling calcium carbide.
Transferring Calcium Carbide
- Use a charging skip or specialized transfer equipment, ensuring proper groundingduring transfer.
-All transfer tools should be equipped with gas-purging systems and anti-staticproperties.
Cleaning up Spillage
-Use natural fiber brooms and non-sparking tools to sweep up any spillage during transfer.
-Calcium carbide dust should be disposed of safely.
