Calcium Carbide Granule

Calcium carbide granules are a key processed form of Calcium Carbide (CaC₂). Industrially produced in an electric arc furnace at ~2,200 °C, they are essential for generating acetylene, steelmaking, and more. Our industrial-grade product meets strict standards (GB209-2006) and is verified by international inspections (SGS/CIQ/BV). Wanding supplies this reliable, high-quality product for global industrial needs.

 

 

Calcium Carbide Granule Applications

• Acetylene Gas Production: Generates a portable and on-demand fuel source for metal cutting/welding and chemical synthesis.
• Steelmaking (Desulfurizer): Efficiently removes sulfur impurities from molten iron/steel to improve product quality.
• Calcium Cyanamide Production: Serves as a key precursor for nitrogen fertilizers and various industrial chemicals.
• Other Industrial Uses: Assists in wastewater treatment (phosphate removal) and acts as a powerful desiccant.

Calcium Carbide Granule Advantages

Calcium carbide granules offer significant practical and operational advantages over other forms (like lumps or powder), making them the preferred choice for industrial applications.

1. Enhanced Reaction Efficiency & Control
Larger surface area allows for faster, more complete, and more controllable reactions, whether for acetylene generation or steel desulfurization, leading to consistent gas yield and precise process control.

2. Superior Safety & Handling
The granular form significantly reduces the risk of dust explosion hazards associated with fine powder. It is easier and safer to transport, store, and feed into reaction systems using automated equipment.

3. Optimized Storage & Transport
Granules have better flow characteristics and are less prone to caking or absorbing moisture uniformly compared to fine powder, improving material stability during storage and logistics.

4. Consistent Quality & Uniformity
Sized particles ensure batch-to-batch consistency in chemical composition and reaction rate, which is critical for stable and predictable industrial processes.

5. Cost-Effectiveness
Reduced reaction time, minimal waste, precise dosing, and lower safety management requirements contribute to overall lower operational costs.

FAQ

Q: Where is your plant located?

A: Our calcium carbide factory is located in Ningxia, which is near carbide raw material place.  It covers an area of 6000 aquare meters.With monthly production capacity of 8000 tons.

 

Q: How can you guarantee the quality? 

A: We will take a lot of sampling testing second time during carbide processing to ensure products with good gas yield. 

We often do air pressure testing to drums, ensure carbide drums seals tight and safety.

We will take sampling test again before goods loading, ensures loaded goods with correct weight, sizes, gas yield and quantity.

Our carbide Production is based on Chinese National Standard: GB10665-2004.

We accept on-site inspection at Shanghai port and randomly select a barrel to check the quality of the goods. If the quality is not qualified, you do not have to work with us.

 

Q:  What is the gas yield of your product?

A: Typically, the gas yield of the particle size 80-120mm, 50-80mm, 25-50mm  is 295L/kg~305L/kg.

 

Q: What is the delivery time? 

A: It is usually within 15 working days after receiving the deposit or original L/C. 

 

Q: What is your minimum order quantity (MOQ)?

A: One container, usually 22.5t.

 

Q: Can I request a sample before placing a bulk order?

A: No, but we support pre-shipment port inspection.

 

Q: What are your main shipping terms and delivery ports?

A: Usually CIF/FOB, with Shanghai or Tianjin ports.
