TYWH IS THE WORLD'S LEADING SUPPLIER OF CALCIUM CARBIDE FOR USE IN THE DUCTILE IRON DESULFURIZATION

The graphite in ductile iron is spherical, a shape that inhibits cracking and thus enhances ductility, hence the name of the alloy. During production sulphur interferes with the spheroidisation process and inhibits the formation of ductile graphite. TYWH 4-7mm calcium carbide has become the preferred desulphurising agent for ductile iron due to its powerful desulphurising and deoxidising properties.

What are the main uses of calcium carbide?

Calcium carbide is a key raw material for the production of acetylene, which is generated through a chemical reaction with water. It is also used in the desulfurization and deoxidation processes in steelmaking to improve the quality of steel.

How can you select the appropriate calcium carbide product to maximize your production efficiency?

Our sales managers and technical team are available to offer customized calcium carbide particle size recommendations based on your specific production needs and equipment specifications.

How can the reliability of calcium carbide supply be guaranteed to avoid disruptions in manufacturing?

Our fully automated production lines ensure production stability and the reliability of the calcium carbide supply is ensured through the implementation of a comprehensive supply chain management strategy covering supplier management, production supervision, inventory control and logistics coordination.

What safety measures should be considered when utilizing calcium carbide in the manufacturing process?

We provide nitrogen-filled drums to ensure safety during transportation, as well as comprehensive safety guidelines (including fire safety, explosion-proofing and the use of personal protective equipment). In addition, we have professional staff available 24/7 to provide you with service and support.

How long is the delivery lead time?

Delivery takes about 15 days after receipt of prepayment or LC.

What are the necessary conditions for storing calcium carbide?

Calcium carbide must be stored in airtight containers and placed in an environment that is dry and well-ventilated to prevent contact with water.

The relationship between the gas yield and calcium carbide is as following.
CaC2 (%)	63.14	68.52	72.54	73.89	75.2	76.57	77.91	80.6
Gas Yield(L/Kg)	235	255	270	275	280	285	290	300
