App
Detailed description
CYY-LK2 is a dedicated liquid iron thermal analyzer for mold front operations, enabling foundries to monitor cast iron composition at the furnace before pouring. This device belongs to the liquid iron thermal analyzer series and uses thermal analysis methods to rapidly determine carbon and silicon content, along with key thermal parameters of molten iron.
In cast iron production, analyzing the molten iron composition at the furnace front is a critical step to ensure casting quality. The carbon and silicon content in liquid iron directly affects: - Cast iron type (gray, ductile, or white iron) - Mechanical properties of the casting - Post-casting machinability - Defect rate
CYY-LK2 performs rapid molten iron composition analysis in up to 240 seconds. Analysis results enable operators to adjust furnace-side composition in real time, reduce defect rates, and improve production efficiency.
Display and print results
CYY-LK2 has two result display formats:
1. LED Digital Display: 4-digit LED display with 50mm digit height. The operator can press the button to display CEL, C%, or Si%. Pressing the cycle button sequentially displays all parameters.
2. Embedded thermal printer: The device features an embedded thermal printer that automatically prints full English results, including measured temperature, carbon content, silicon content, carbon equivalent, hardness estimation, tensile strength, and other parameters. If the paper runs out, printing stops but the LED display remains unaffected.
What is a liquid iron thermal analyzer?
The molten iron thermal analyzer is an advanced testing device used in foundries to analyze the solidification behavior of molten metal.
Unlike traditional laboratory testing methods that require longer preparation times, thermal analysis provides rapid information directly at the furnace side.
During measurement, a small amount of molten iron is poured into the thermal analysis cup equipped with a thermocouple. The device records temperature changes during cooling and generates a cooling curve.
Based on this curve, the system calculates key metallurgical parameters related to: - Carbon content - Silicon content - Carbon equivalent - Eutectic reaction - Solidification behavior - Casting quality assessment
Why is thermal analysis critical in iron foundries?
The quality of cast iron depends heavily on the composition of the molten metal and its solidification characteristics.
Before pouring, the foundry must verify: - Is the carbon equivalent within the required range? - Is graphite formation appropriate? - Is the molten iron quality stable? - Do the castings meet the required mechanical properties?
CYY-LK2 provides fast feedback, allowing operators to adjust the batch before casting.
This helps reduce: - Shrinkage defects - Porosity issues - Incorrect graphite structure - Casting scrap rate - Production waste
Main functions of the liquid iron analyzer CYY-LK2
Analyze cooling curve
CYY-LK2 automatically records the cooling curve of molten iron and analyzes characteristic temperature points during solidification.
Key parameters include: - Liquidus temperature (TL) - Eutectic temperature - Solidus temperature - Undercooling characteristics - Carbon equivalent (CEL)
Measure carbon equivalent
Carbon equivalent is one of the most critical indicators for cast iron production.
The system helps operators monitor: - Carbon levels - Silicon impact - Solidification trends
This enables better control over: - Gray cast iron - Ductile (nodular) cast iron - Malleable cast iron
Metal quality assessment
The analyzer provides valuable information to evaluate: - Molten iron condition - Graphite formation trends - Casting stability - Predicted mechanical properties
