Stable Supply for Continuous Production
We maintain consistent raw materials and controlled production processes to guarantee stable batch performance.
Reduced Procurement Risk
Third-party certification helps buyers simplify supplier approval and avoid quality disputes.
Applications
Purpose: Deoxidation and alloy efficiency improvement
How it works:
Silicon carbide reacts with oxygen in molten steel, acting as a compound deoxidizer (Si + C). Compared with single deoxidizers, it provides a more balanced reaction.
Key Benefits:
Reduces oxygen content and non-metallic inclusions
Improves steel cleanliness and mechanical properties
Enhances alloy recovery rate (especially Si and C)
Helps stabilize tapping composition
Purpose: Inoculation and carbon/silicon adjustment
How it works:
SiC decomposes in molten iron, supplying both silicon and carbon, promoting graphite formation and improving microstructure.
Key Benefits:
Improves graphite morphology (finer and more uniform)
Reduces chill tendency
Enhances casting strength and machinability
Stabilizes chemical composition during melting
Purpose: Slag modification and impurity control
How it works:
SiC reacts with oxidizing slag, reducing FeO content and improving slag fluidity.
Key Benefits:
Promotes faster slag-metal separation
Reduces metal loss in slag
Improves furnace efficiency
Supports cleaner steel production
Purpose: High-temperature resistance and durability
How it works:
Due to its high thermal conductivity and oxidation resistance, SiC is used in refractory mixes and coatings.
Key Benefits:
Improves thermal shock resistance
Extends refractory service life
Enhances heat transfer efficiency
Maintains structural stability at high temperatures
Purpose: Cost optimization and process efficiency
How it works:
SiC can partially replace ferrosilicon and carburizers, providing dual-element input (Si + C).
Key Benefits:
Reduces total material cost
Simplifies alloy addition process
Improves absorption efficiency
Lowers overall consumption in some applications
