Fine & Uniform Granulation: Screened precisely to 7-15mm to ensure rapid hydration, consistent material feeding, and high reaction reactivity.
Diverse Industrial Uses: Widely utilized in rapid acetylene gas generators, ladle metallurgical desulfurization, and specialty organic synthesis.
Air-Tight Packaging: Sealed in nitrogen-flushed, moisture-resistant 50 kg or 100 kg steel drums compliant with UN 1402 Class 4.3 transport safety standards.
In precision chemical manufacturing and metallurgical engineering, selecting the proper granulation size directly impacts operational efficiency, gas yield velocity, and material handling accuracy. Calcium carbide ($CaC_2$) remains an essential raw chemical feedstock used across various heavy industrial sectors. Within specialized sizing categories, calcium carbide 7-15mm represents a small-granule distribution specifically formulated for applications requiring rapid decomposition and high reactive surface area.
By offering a smaller lump profile, this fine-grained chemical material provides distinctive operational advantages for continuous automated feed systems and specialized gas generation setups.
Calcium carbide is synthesized by reacting high-purity quicklime with carbon-rich coke inside electric arc furnaces at extreme temperatures. Following cooling, the solidified compound is crushed and passed through multi-deck mechanical sieves to isolate exact particle dimensions.
Choosing calcium carbide 7-15mm delivers distinct performance benefits for industrial plant managers and procurement teams:
The core commercial use of fine-grade calcium carbide 7-15mm is the rapid generation of acetylene gas. Industrial gas suppliers and portable generator operators utilize this size for quick-response gas output needed in high-temperature cutting, welding, and surface treatment operations.
In modern secondary metallurgy, controlling sulfur concentrations is critical for high-tensile steel alloys. Fine carbide granules act as a potent desulfurizing agent when added to liquid steel, forming calcium sulfide slag and elevating metal ductility and strength.
Beyond thermal applications, acetylene liberated from small-granule carbide serves as a essential chemical intermediate in manufacturing vinyl monomers, synthetic rubbers, organic solvents, and specialty agrochemicals.
