In a modern foundry, molten iron quality needs to be checked before pouring, not only after the casting has been produced.
For gray iron, ductile iron and other cast iron applications, thermal analysis provides a fast method for monitoring the solidification behavior of a small molten metal sample.
CYY-QC1 is a square Thermal Analysis Sampling Cup developed by Nanjing Changyouyi Analysis Instrument Co., Ltd. for compatible foundry thermal analysis applications.
It is designed for customers looking for a practical molten iron sampling cup, thermal analysis cup, carbon cup or square Quick Cup for use with an appropriate thermal analysis instrument.
A thermal analysis cup is a disposable refractory sampling container used to hold a small quantity of molten metal while its temperature changes during cooling and solidification.
A sensor/thermocouple associated with the cup records the temperature curve. The thermal analysis instrument then processes the cooling curve to identify important thermal characteristics.
Depending on the instrument, cup configuration and application, thermal analysis can be used to evaluate parameters such as:
Carbon Equivalent (CE / CEL)
Carbon Content (C%)
Silicon Content (Si%)
Liquidus Temperature
Eutectic Temperature
Undercooling
Cooling Curve
Solidification Characteristics
This type of cup is therefore much more than an ordinary metal sampling container. It is an important consumable component of a molten iron quality-control system.
The CYY-QC1 uses a square cup configuration.
Square thermal analysis cups are widely recognized in the foundry industry for applications involving molten iron thermal analysis and carbon-silicon analysis. Current international product terminology includes square thermal analysis cup, carbon cup, CE cup and thermal analysis sampling cup.
CYY-QC1 is intended for customers who already operate a compatible thermal analysis system and need a replacement or regular supply of square sampling cups.

The major advantage of thermal analysis is that a foundry does not necessarily have to wait for the finished casting to discover a melt-quality problem.
A small molten iron sample can be taken from the furnace or ladle and tested before pouring.

This makes thermal analysis particularly useful for foundries producing large numbers of heats where rapid process feedback is important.
CYY-QC1 is positioned as a professional square thermal analysis cup for compatible established thermal analysis systems.
For customers replacing an existing cup, we recommend confirming the physical and functional configuration before ordering.
Different instruments may use different:
Cup dimensions
Thermocouple arrangements
Cup geometry
Sensor positions
Thermal characteristics
Connection configurations
Therefore, the same generic term “Thermal Analysis Cup” does not necessarily mean that every cup is interchangeable.
This is particularly important when customers are replacing cups originally supplied with an existing thermal analysis instrument.
Thermal analysis depends on the temperature change of the molten metal sample.
Therefore, cup geometry and material characteristics can influence the cooling behavior of the sample. Industry guidance also highlights cup geometry, wall thickness, thermocouple position and material composition as important factors for repeatable thermal-analysis results.
For this reason, Changyouyi recommends purchasing compatible cups as a consistent consumable rather than mixing random cup types from different suppliers.
CYY-QC1 is suitable for customers sourcing foundry consumables from China for applications in:
Pakistan
India
Bangladesh
Vietnam
Indonesia
Thailand
Brazil
Mexico
Colombia
Peru
Chile
Argentina
South Africa
Middle East and other developing industrial markets
For distributors and foundry equipment suppliers, Changyouyi can also supply the CYY-QC series as part of a complete carbon-silicon analyzer consumables program.
Changyouyi develops both instruments and related consumables for molten iron analysis.
Our product system includes:
CYY-LK Series
Carbon-Silicon Analyzers / Molten Iron Thermal Analysis Instruments
CYY-QC Series
Square Quick Thermal Analysis Cups
CYY-CE Series
Carbon Equivalent / Carbon-Silicon Analysis Round Cups
CYY-SG Series
Thermal Analysis Cups for Spheroidization/Nodularity Applications
This allows customers to purchase both analysis instruments and matching consumables from the same manufacturer.
Before ordering thermal analysis cups, customers are encouraged to send:
1. A photo of the cup currently being used
2. A photo of the packaging label
3. A photo of the thermal analysis instrument
4. The instrument model, if available
Changyouyi can then check the application and recommend the appropriate cup configuration.
