The CYY-LK2 Carbon Silicon Analyzer is a professional instrument designed for foundries that require rapid measurement of carbon and silicon content in molten iron.
Carbon and silicon are two critical elements affecting cast iron structure, mechanical properties, and casting performance.
By combining thermal analysis technology with intelligent calculation methods, the CYY-LK2 quickly determines:
Carbon percentage (C%)
Silicon percentage (Si%)
Carbon Equivalent (CEL)
Eutectic degree (SC)
Thermal parameters
The system helps foundries make accurate melting adjustments before casting.

A carbon silicon analyzer is a specialized instrument used to measure carbon and silicon levels in molten cast iron.
Traditional chemical analysis methods may require laboratory preparation and longer testing time.
A furnace-side carbon silicon analyzer provides rapid information directly during production, helping operators control molten iron composition immediately.
In cast iron production, carbon and silicon directly influence:
Graphite structure
Fluidity
Hardness
Tensile strength
Machinability
Casting defects
Incorrect carbon or silicon levels may cause:
Poor casting quality
Excessive hardness
Low strength
Defective microstructure
The CYY-LK2 helps maintain stable chemical composition.
The instrument analyzes carbon content to help control:
Graphite formation
Solidification behavior
Mechanical properties
Silicon measurement helps optimize:
Ferrite formation
Fluidity
Casting performance
Carbon equivalent is automatically calculated based on measured thermal characteristics.
This provides a quick evaluation of molten iron condition.
For unalloyed cast iron, the system can estimate:
Tensile strength (RM)
Hardness (HB)
Helping foundries improve process control.
Results are available quickly after sampling.
Better control of molten iron composition reduces production problems.
Early detection prevents:
Incorrect pouring
Material waste
Casting rejection
Designed for furnace operators:
Easy sampling
Automatic calculation
Digital display
Optional printing record
CYY-LK2 is widely used in:
Cast iron foundries
Ductile iron production
Automotive casting
Agricultural machinery casting
Pipe manufacturing
Industrial component casting
