Fast Carbon and Silicon Measurement Equipment for Molten Iron Quality Control

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.

What Is a Carbon Silicon Analyzer?

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.

Why Carbon and Silicon Control Matters

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.

Main Functions of CYY-LK2 Carbon Silicon Analyzer

Carbon Content Measurement (C%)

The instrument analyzes carbon content to help control:

• Graphite formation

• Solidification behavior

• Mechanical properties

Silicon Content Measurement (Si%)

Silicon measurement helps optimize:

• Ferrite formation

• Fluidity

• Casting performance

Carbon Equivalent Calculation (CEL)

Carbon equivalent is automatically calculated based on measured thermal characteristics.

This provides a quick evaluation of molten iron condition.

Tensile Strength and Hardness Prediction

For unalloyed cast iron, the system can estimate:

• Tensile strength (RM)

• Hardness (HB)

Helping foundries improve process control.
