Calcium Carbide Granules: Industrial Applications and Production Process
Release Time:
2026-06-11
Calcium carbide granules represent a critical industrial material produced through high-temperature electrochemical processes. Ningxia Wanding Chemical Co., Ltd., operating since 2002 with monthly production capacity of 6,000-8,000 tons, manufactures industrial-grade calcium carbide granules meeting GB209-2006 standards.
The calcium carbide granules manufacturing process involves electrothermal reduction of lime and coke at 2,200°C. According to GB10665-2004 standards, industrial calcium carbide must demonstrate minimum CaC2 purity of 90%, with gas yield of 295-305 L/kg.
The 2-7mm granular form provides optimal balance between reaction speed and controllability. Larger particles (25-50mm) suit steel desulfurization processes where sustained calcium release improves impurity removal efficiency.
Primary applications include acetylene gas production for metal cutting and welding, steelmaking desulfurization reducing sulfur content from 0.03-0.05% to below 0.01%, and calcium cyanamide synthesis for nitrogen fertilizers.
Industrial-grade calcium carbide granules must meet specifications: CaC2 Purity minimum 90%, Gas Yield 295-305 L/kg, Moisture Content below 0.5%. Safety protocols mandate storage in cool, dry areas with moisture barriers, sealed iron drums packaging, and dry sand for fire suppression.
Calcium carbide granules provide essential functionality across acetylene production, steel desulfurization, and chemical synthesis applications. Selecting appropriate particle sizes ensures optimal performance for specific industrial requirements.
