TYWH Calcium Carbide Manufacturing Process

Each batch of calcium carbide undergoes strict quality testing upon arrival to ensure that only high-quality materials enter the production process. Key inspection criteria include:

Acetylene Gas Yield: We verify that the calcium carbide produces sufficient acetylene gas when reacting with water, meeting industry demands.

 PH₃ and H₂S Content: The levels of these toxic gases are carefully controlled to ensure safe operation and maintain product quality.

Impurity Levels: We measure the amount of non-calcium carbide materials to minimize impurities.

This thorough testing process ensures that only the highest-quality raw materials proceed to the production stages.

Our state-of-the-art jaw crushers efficiently crush the raw calcium carbide to meet size requirements. The crushing process is divided into multiple stages to ensure that every piece of calcium carbide reaches the desired size.

Each production area is equipped with acetylene concentration alarms, which monitor the concentration of acetylene gas in the environment, ensuring the safety of both workers and the facility.

We utilize advanced vibration screening equipment with multiple mesh layers for precision particle sizing. This high-precision technology ensures that over 90% of the calcium carbide particles meet size specifications, providing consistency and reliability in particle size distribution.

To enhance product purity, we implement multiple impurity removal techniques:

High-Powered Electromagnets: These effectively remove iron-based impurities from the calcium carbide.

Manual Sorting: Non-magnetic impurities, such as ferro-silicon, are manually screened out, further improving product purity.

This process significantly reduces impurity levels, leading to a higher-quality product with superior performance.

Our fully automated packaging line ensures efficient, precise, and safe packaging. Key steps in the process include:

Automated Filling: Minimizes human interference, reducing the risk of contamination.

Electronic Weighing: Ensures that each package meets precise weight requirements, preventing underweight issues.

Automated Sealing: Increases the airtightness of packaging, preventing moisture and air from entering.

This automated process optimizes production efficiency while ensuring consistent and reliable final products.

To protect the health of our employees and minimize environmental impact, we employ a fully enclosed dust control system throughout the production stages (crushing, screening, and packaging). This system captures dust generated during production, maintaining a clean working environment and reducing emissions.

We conduct random sampling of 15 kg from every 10 tons of finished product for detailed testing. Tests include:

Particle Size Compliance: Ensures that the particle size meets customer specifications.

Acetylene Gas Yield: Confirms that the gas output from the calcium carbide meets industry standards.

Phosphine (PH₃) and Hydrogen Sulfide (H₂S) Content: Ensures that the levels of these toxic impurities remain within safe limits.

Impurity Levels: Verifies that non-active substances are within acceptable levels.

Any non-conforming products are immediately discarded to ensure that only high-quality calcium carbide reaches the market.

After sealing, we inject nitrogen gas into the calcium carbide drums, displacing residual air and flammable gases. This step prevents the carbide from weathering, maintaining product stability over time. It also enhances the safety of storage and transportation.

We adhere to strict safety storage standards to ensure the safe handling of calcium carbide. Key measures include:

Fire and Water Protection: Prevents potential damage from fire or water incidents.

Temperature and Humidity Control: Calcium carbide is stored in optimal conditions to avoid degradation due to environmental factors.

These precautions ensure that the calcium carbide remains safe and of high quality during storage, ready for global distribution.

TYWH’s production process not only ensures the highest quality and safety of calcium carbide but also complies with industry best practices and environmental standards. We are committed to delivering premium-grade calcium carbide to acetylene manufacturers and steelmakers worldwide.
