CYY-LK7 Molten Iron Thermal Analyzer for Foundries

In cast iron production, molten iron quality determines the final casting quality. Before pouring, foundries must verify whether the melt meets required metallurgical conditions. Temperature alone is insufficient. Production teams may also need to assess carbon equivalent, carbon, silicon, manganese, solidification behavior, and other metallurgical indices.

This is where thermal analysis becomes a critical tool for process control.

CYY-LK7 The liquid iron thermal analyzer is designed for rapid analysis of molten iron using a thermal analysis method based on the cooling curve.

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.

Equipment for foundries producing gray iron, ductile iron, and other cast iron products, providing rapid molten iron quality data prior to casting.

What is molten iron thermal analysis?

Melt analysis is a method for evaluating molten cast iron by monitoring temperature changes in a representative sample during cooling and solidification.

Liquid iron sample is poured into a dedicated sample cup. CYY-LK7 monitors temperature changes and analyzes the resulting cooling curve.

Thermal behavior is measured and then used to calculate or evaluate key metallurgical parameters.

This provides foundry operators with information to use before pouring molten iron into the mold.

In actual production, the process can be summarized as: Molten iron sampling → Cooling curve measurement → Thermal analysis → Result evaluation → Process adjustment → Casting

This makes thermal analysis particularly valuable for foundries that require rapid process feedback.

Why use a molten iron analyzer in the foundry?

Traditional production processes often rely heavily on chemical laboratory testing and final product inspection.

Laboratory analysis remains important, but it may not always provide the operator with the immediate information needed.

The liquid iron thermal analyzer provides process data closer to the furnace and casting operations.

For example, the production team can use analysis results to evaluate: - Carbon Equivalent (CEL) - Carbon Content (C%) - Silicon Content (Si%) - Manganese Content (Mn%) - Alloying Ratio - Predicted Tensile Strength - Predicted Brinell Hardness

The goal is not merely to obtain a measurement. The goal is to provide foundries with practical tools for controlling molten iron quality before casting.

Thermal analysis parameters CYY-LK7

CYY-LK7 is designed to analyze multiple parameters related to cast iron production: - 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% - Nodularity Ratio: 60-99%, accuracy ±5% - Tensile Strength: 150-400 MPa, accuracy ±10 MPa - Brinell Hardness: 100-300 HB, accuracy ±10 HB

These parameters enable the device to perform more than simple temperature measurements.

Analyze 90 seconds to control production

One of the key requirements in a foundry environment is speed.

Furnace operators often cannot wait for lengthy lab analysis before deciding whether molten iron is ready for the next production step.

CYY-LK7 provides analysis within 90 seconds, depending on sampling conditions and actual measurements.

This makes it ideal for production environments where multiple batches or pouring containers need to be inspected within a single shift.

Basic operation process is simple: 1. Collect representative liquid iron sample — Extract an appropriate amount of liquid iron from the furnace or processing line 2. Pour sample into dedicated cup — Position the cup for measurement 3. Measure cooling curve — The analyzer records temperature changes during cooling and solidification 4. Calculate required parameters — The system processes the cooling curve and provides relevant analysis results 5. Make production decisions — Operators can use the results as reference to adjust the liquid iron before casting

Thermal analysis for gray cast iron and ductile iron

Different types of cast iron require different process control considerations.

Gray Iron Foundry: For gray iron production, balancing carbon and silicon is critical to maintaining consistent metallurgical conditions. CYY-LK7 can provide data including CEL + C% + Si% + Mn%. This enables production staff to compare the current melt against required process targets.

Ductile Iron Foundry: For ductile iron production, the foundry may have additional requirements related to nodularization. CYY-LK7 includes a nodularization ratio measurement function and can also provide predicted tensile strength and Brinell hardness values. This makes it useful as part of a broader ductile iron quality control process.

Analyze the cooling curve instead of just measuring temperature.

Standard thermometers primarily inform operators of molten metal temperature. Thermal analyzers provide additional insights by monitoring how the sample cools and solidifies.

This distinction is critical. For foundry process control, operators may need to answer questions such as: - Is the molten iron within the required composition range? - Is the carbon equivalent appropriate? - Is the silicon level suitable? - Is the molten iron quality consistent across heats? - Does nodularization produce the expected results? - Is the heat ready for pouring?

The thermal analysis system can provide additional data to support these decisions.

Log and analyze history

Quality control becomes more effective when measurement results can be compared over time.

CYY-LK7 supports data logging and historical review. According to product specifications, the system can store over 5.000 measurement records and allows viewing of historical measurement data and cooling curves.

Optional data interfaces can also support data transmission. This enables foundries to establish a basic workflow: Measure → Record → Compare → Analyze → Adjust → Improve

For plants with multiple production shifts, this type of historical record also helps technicians investigate differences between batches.

Sample cups for various analytical applications

Sampling is a critical component of thermal analysis. Application CYY-LK7 uses specialized sample holders for various measurement purposes.

To measure composition, use a dedicated sample cup with tellurium particles. To measure the degree of crosslinking and predict related mechanical properties, use a sample cup without tellurium particles.

Using the appropriate sample cup for your measurement purpose ensures that the test method aligns with your intended analysis.
