In modern foundries, controlling molten iron quality before pouring is essential for producing stable and high-quality castings. The CYY-LK2 Molten Iron Thermal Analysis System is a professional front-furnace thermal analysis instrument designed for cast iron foundries to quickly evaluate metallurgical conditions of molten iron.
By analyzing the cooling curve of molten iron, the CYY-LK2 provides important parameters including liquidus temperature, eutectic temperature, carbon equivalent (CEL), solidification characteristics, and metallurgical quality indicators.
The system helps foundries optimize furnace operation, reduce casting defects, improve production efficiency, and achieve better control of gray iron, ductile iron, and other cast iron materials.
A molten iron thermal analysis system is an advanced testing instrument used in foundries to analyze the solidification behavior of molten metal.
Unlike traditional laboratory testing methods that require longer preparation time, thermal analysis provides rapid information directly at the furnace side.
During measurement, a small amount of molten iron is poured into a thermal analysis sample cup equipped with a thermocouple. The instrument records the temperature change during cooling and generates a cooling curve.
Based on this curve, the system calculates important metallurgical parameters related to:
Carbon content
Silicon content
Carbon equivalent
Eutectic reaction
Solidification behavior
Casting quality evaluation

The quality of cast iron depends strongly on molten metal composition and solidification characteristics.
Before pouring, foundries need to know:
Is the carbon equivalent within the required range?
Is the graphite formation suitable?
Is the molten iron quality stable?
Will the casting achieve the required mechanical properties?
The CYY-LK2 provides fast feedback, allowing operators to adjust the melt before casting.
This helps reduce:
Shrinkage defects
Porosity problems
Incorrect graphite structure
Casting rejection rates
Production waste
The CYY-LK2 automatically records the cooling curve of molten iron and analyzes the characteristic temperature points during solidification.
Important parameters include:
Liquidus Temperature (TL)
Eutectic Temperature
Solidus Temperature
Undercooling Characteristics
Carbon Equivalent (CEL)
Carbon equivalent is one of the most important indicators for cast iron production.
The system helps operators monitor:
Carbon level
Silicon influence
Solidification tendency
This allows better control of:
Gray iron
Ductile iron
Malleable iron
