Advanced Thermal Analysis Equipment for Real-Time Molten Iron Quality Control

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.

What Is a Molten Iron Thermal Analysis System?

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

• 
  

Why Thermal Analysis Is Important in Iron Foundries

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

Key Functions of CYY-LK2 Thermal Analysis Equipment
