In cast iron production, the quality of molten iron can determine the quality of the final casting.
Before molten iron is poured into a mold, foundries need to know whether the melt has reached the required metallurgical condition. Temperature alone cannot provide enough information. Production teams may also need to evaluate carbon equivalent, carbon, silicon, manganese, solidification behavior and other metallurgical indicators.
This is where thermal analysis becomes an important process-control tool.
The CYY-LK7 Intelligent Carbon-Silicon-Manganese Analyzer is designed for rapid analysis of molten iron using a cooling-curve-based thermal analysis method.
It is intended for foundries producing gray iron, ductile iron and other cast iron products where fast information about molten iron quality is required before casting.
Molten iron thermal analysis is a method of evaluating molten cast iron by monitoring the temperature change of a representative sample during cooling and solidification.
A molten iron sample is poured into a dedicated sample cup. The CYY-LK7 monitors the temperature change and analyzes the resulting cooling curve.
The measured thermal behavior is then used to calculate or evaluate important metallurgical parameters.
This provides the foundry operator with information that can be used before pouring the molten iron into the mold.
In practical 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 useful for foundries that need rapid process feedback.
A traditional production process may rely heavily on chemical laboratory testing and final product inspection.
Laboratory analysis remains important, but it may not always provide the immediate information required by a furnace operator.
A molten iron thermal analyzer can provide process information much closer to the furnace and casting operation.
For example, the production team may use the analysis result to evaluate:
Carbon Equivalent (CEL)
Carbon Content (C%)
Silicon Content (Si%)
Manganese Content (Mn%)
Spheroidization Rate
Predicted Tensile Strength
Predicted Brinell Hardness
The objective is not simply to obtain a measurement. The objective is to give the foundry a practical tool for molten iron quality control before casting.
The CYY-LK7 is designed to analyze several parameters relevant to cast iron production.
| Measurement Item | Measuring Range | Accuracy |
|---|---|---|
| Carbon Equivalent (CEL) | 2.50–4.80% | ±0.08% |
| Carbon Content (C%) | 2.30–4.20% | ±0.05% |
| Silicon Content (Si%) | 0.60–3.80% | ±0.10% |
| Manganese Content (Mn%) | 0.10–1.40% | ±0.15% |
| Spheroidization Rate | 60–99% | ±5% |
| Tensile Strength | 150–400 MPa | ±10 MPa |
| Brinell Hardness | 100–300 HB | ±10 HB |
These parameters allow the instrument to be used for more than simple temperature measurement.
One of the important requirements in a foundry environment is speed.
A furnace operator cannot normally wait for a long laboratory analysis before deciding whether the molten iron is ready for the next production step.
The CYY-LK7 provides analysis in approximately 90 seconds, depending on the actual sampling and measurement conditions.
This makes it suitable for production environments where multiple heats or ladles need to be checked during a working shift.
The basic operating process is straightforward:
A suitable quantity of molten iron is taken from the furnace or molten iron process.
The sample cup is positioned for measurement.
The analyzer records the temperature change during cooling and solidification.
The system processes the cooling curve and provides the relevant analytical results.
The operator can use the results as a reference for molten iron adjustment before casting.
Different types of cast iron require different process-control considerations.
For gray iron production, controlling the balance between carbon and silicon is important for maintaining consistent metallurgical conditions.
The CYY-LK7 can provide information including:
CEL + C% + Si% + Mn%
This allows production personnel to compare the current melt with the required process targets.
For ductile iron production, the foundry may have additional requirements related to spheroidization.
The CYY-LK7 includes a spheroidization rate 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.
A conventional temperature meter mainly tells the operator the temperature of molten metal.
A thermal analyzer provides additional information by observing how the sample cools and solidifies.
This difference is important.
For foundry process control, the operator may need to answer questions such as:
Is the molten iron within the required composition range?
Is the carbon equivalent suitable?
Is the silicon level appropriate?
Is the molten iron condition stable between heats?
Is the ductile iron treatment producing the expected result?
Is the melt suitable for pouring?
A thermal analysis system can provide additional data to support these decisions.
Production quality control becomes more useful when measurement results can be compared over time.
The CYY-LK7 supports data recording and historical data review.
According to the product information, the system can store more than 5,000 measurement results and allows historical measurement data and cooling curves to be reviewed.
Optional data interfaces can also support data transfer.
This allows a foundry to build a basic workflow:
Measure → Record → Compare → Analyze → Adjust → Improve
For factories with multiple production shifts, this type of historical record can also help technicians investigate variations between heats.
The sampling method is an important part of thermal analysis.
The CYY-LK7 application uses dedicated sample cups for different measurement purposes.
For composition measurement, a dedicated sample cup with tellurium granules is used.
For spheroidization rate and related mechanical-property prediction, a sample cup without tellurium granules is used.
Using the appropriate sampling cup according to the measurement purpose helps ensure that the test method corresponds to the intended analysis.
The CYY-LK7 can be considered for:
Gray iron foundries
Ductile iron foundries
Automotive casting plants
Valve manufacturers
Pipe casting manufacturers
Machinery casting factories
General engineering foundries
Induction furnace operations
Cast iron component manufacturers
Foundry production lines requiring rapid molten iron analysis
For customers in Pakistan, India, Brazil, Argentina, Colombia, Chile, Peru, South Africa and other casting markets, the instrument can be used as an on-site molten iron quality-control tool.
