CYY-LK7 Intelligent Carbon-Silicon-Manganese Analyzer

In modern foundries, controlling the chemical composition of molten iron is a critical part of production management. Among the various elements in cast iron, carbon, silicon, and manganese are particularly important process parameters.

If molten iron composition falls outside the target range, the final casting may fail to meet required metallurgical or mechanical properties. For this reason, many foundries require fast carbon-silicon analyzers that provide real-time compositional data during melting and pouring.

CYY-LK7 Smart Carbon-Silicon Analyzer developed for this application.

Core Feature: Carbon-Silicon Analyzer

CYY-LK7 is primarily a carbon-silicon analyzer. Its core function is to measure the carbon (C%) and silicon (Si%) content in molten iron, as well as the carbon equivalent (CEL). These are key parameters that determine cast iron quality.

In addition to its primary functions of measuring C and Si, the device offers supplementary features and predictive values: - Manganese content (Mn%): reference value - Nodularity ratio: reference value (for ductile iron) - Tensile strength: predicted - Brinell hardness: predicted

These predicted and reference values provide operators with additional information to support decision-making, but the core functionality of the device remains focused on measuring C, Si, and CEL.

Sampling and Quality Control Process

Due to pour temperature requirements, the standard quality control process is: 1. Sample molten iron directly from the furnace (temperature: 1300℃～1400℃) 2. Pour sample into a dedicated analysis cup 3. CYY-LK7 Analyze the cooling curve (cup temperature: 1250℃～1350℃) 4. Read C%, Si%, and CEL results within 90 seconds 5. If composition meets requirements → discharge for casting 6. If not met → adjust pre-pour composition, re-sample, and re-test

This process ensures molten iron is poured only when it meets target composition requirements, minimizing defects and waste.

Machine Placement and Operating Environment

CYY-LK7 is heat-resistant and dust-proof, designed for furnace-front environments. The device can be installed anywhere that meets the following conditions: - No direct drafts - No rain exposure - No strong electromagnetic interference - Not installed in electrical cabinets or electrical rooms

The device does not require an air-conditioned or clean room; it operates reliably in a standard foundry environment.

Why are Carbon, Silicon, and Manganese important?

Carbon and silicon are key elements in cast iron production. Their levels influence solidification behavior and melt metallurgical properties.

Manganese is also a critical process parameter for many types of cast iron.

Instead of waiting until casting is complete, the foundry can analyze molten iron samples during production and use the results to adjust the process.

CYY-LK7 provides the following measurement ranges: - Carbon Equivalent (CEL): 2.50-4.80%, accuracy ±0.08% - Carbon (C%): 2.30-4.20%, accuracy ±0.05% - Silicon (Si%): 0.60-3.80%, accuracy ±0.10% - Manganese (Mn%): 0.10-1.40%, accuracy ±0.15% - Spheroidization Ratio: 60-99%, accuracy ±5% - Tensile Strength: 150-400 MPa, accuracy ±10 MPa - Brinell Hardness: 100-300 HB, accuracy ±10 HB

How does CYY-LK7 analyze molten iron?

CYY-LK7 uses a thermal analysis method based on the cooling curve. A representative sample of molten iron is placed in a dedicated sample cup. The device monitors temperature changes during cooling and solidification.

The cooling curve contains information related to the sample's metallurgical behavior. CYY-LK7 processes this data and provides the corresponding analysis results.

The complete concept can be summarized as: Mold → Cooling Curve → Thermal Analysis → C/Si/Mn & CEL Results → Process Decision

Typical analysis time is approximately 90 seconds, making the system ideal for rapid production control.

Real-world Carbon Silicon Analyzer for Foundry Production

Labs are typically designed for detailed chemical analysis. Floor analyzers serve a different purpose.

Operators need fast, accurate data to make decisions while molten iron is still available. This is why a professional carbon-silicon analyzer for molten iron can be invaluable in foundries.

CYY-LK7 can be used near: - Melting furnace - Holding furnace - Treatment station - Ladle preparation area - Casting production line - Ductile iron processing area

The goal is to bring analysis closer to actual production processes.

Carbon equivalent analysis for cast iron

Carbon equivalent (CE) is a critical reference value in cast iron production. Rather than considering individual chemical elements separately, carbon equivalent provides additional insight into the overall carbon status of the melt.

CYY-LK7 has a CEL measurement range of 2.50-4.80% with ±0.08% accuracy. This allows operators to evaluate CEL alongside C%, Si%, and other process data.

CYY-LK7 for ductile iron production

Producing ductile iron requires additional process control compared to many common cast iron applications. Beyond composition, the foundry may also be interested in nodularity efficiency and expected mechanical properties.

CYY-LK7 support: - Cure rate: 60-99% - Provides predicted values for: - Tensile strength: 150-400 MPa - Brinell hardness: 100-300 HB

This enables the analyzer to be used as part of the ductile iron quality control process.

Specialized sample cups for various testing purposes

Accurate sampling is essential for reliable thermal analysis. CYY-LK7 uses purpose-built sample cups.

To measure composition, use a dedicated sample cup containing tellurium particles. To measure spheroidization rate and predict tensile strength/hardness, use a sample cup without tellurium particles.

Therefore, operators should select the appropriate sample cup based on the required test. This distinction is particularly important when the same equipment is used for different quality control tasks involving cast iron.

From analysis results to production adjustments

A foundry analyzer is useful not just for displaying numbers. Results should guide the production team on what to do next.

CYY-LK7 supports automatic or manual calculation of additional components required based on configured production requirements.

For example, when a measurement component fails to meet its target, the analysis results can be used as a reference to determine whether additional alloy material or other feedstock is needed.

The production process can therefore be: Measure → Compare → Calculate → Adjust → Verify → Cast

This approach can help reduce unnecessary trial and error during molten iron preparation.

Store data for product traceability

Foundries typically handle multiple batches daily. Manual recording of all results can make historical data comparison difficult.

CYY-LK7 supports data storage and historical record review. The system can store over 5.000 measurement results and reconstruct historical measurement data and cooling curves.

Optional data export interfaces can also support USB or RJ45 transmission, depending on the configured device.

For manufacturing plants, this creates opportunities for: - Batch-to-batch comparison - Process trend analysis - Quality profiles - Historical review - Production traceability - Process improvement

Where can a carbon-silicon analyzer be used?

CYY-LK7 can be used across various ductile iron casting production environments: - Automotive foundries: Monitor molten iron for casting and automotive components - Valve foundries: Check molten iron composition before casting valve bodies and related parts - Pipe foundries: Support composition control in ductile iron pipe production - Machinery foundries: Monitor C, Si, Mn, and CEL during production - Ductile iron foundries: Analyze composition alongside nodularization evaluation - General engineering foundries: Quickly assess molten iron quality across different batches

Why choose a floor-manufactured C, Si, Mn analyzer?

For many foundries, the key question isn't simply: "Can the equipment measure carbon?"

More helpful questions include: - How quickly can I get results? - Can I analyze molten iron before casting? - Can I also evaluate silicon, manganese, and carbon equivalent? - Can I view historical cooling curves? - Can I use the results to adjust production?

CYY-LK7 is designed around these real-world production requirements.
