Heraeus Thermal Analysis Sample Cup

Heraeus Electric Knight provides a range of consumable productsHeraeus Thermal Analysis Sample CupIt is composed of a well-designed sample cup and a high-precision K-type thermocouple.

Thermal analysis sample cupDue to its speed, simplicity, reliability, and low cost, it is widely used for on-site control of molten iron composition. When molten iron is poured into a sample cup, it gradually solidifies over time. Thermal analysis determines and calculates composition parameters such as CEL, C, and Si based on the temperature plateau of its cooling curve. The carbon equivalent CEL is expressed by the formula% CEL=C+% Si/4+% P/2, and the captured liquidus temperature at the beginning of solidification of the molten iron sample is directly related to this value.

Heraeus Thermal Analysis Sample CupCharacteristics:
*Reasonable and reliable sample cup design ensures correct polarity connection with thermal analysis connectors
*Horizontal quartz protective tube design for faster response speed
*A cooling curve with a wide pouring temperature range, good repeatability, and strong stability
*The high carbon content C is determined by two temperature values: the liquid phase temperature TL and the solid phase temperature TS. The silicon content Si can be calculated by measuring the solid phase temperature, and the silicon value can be calibrated by an adjustment factor that is related to the carbon in the molten iron.

Of course, thermal analysis can also be applied in the following three aspects:
*Pregnancy control is achieved through the measurement of eutectic undercooling to regulate pregnancy. *By measuring the liquid phase temperature and undercooling, predict the mechanical and physical properties of molten iron.
*The calculation of spheroidization rate, based on the principle of relative thermal conductivity, can calculate the spheroidization rate of ductile iron and molten iron.

Model and its application:
*Nickel free sample cup (QC4010): Determination of CEL undercooling
*Tellurium containing sample cup (QC4011): Determination of CEL, C, Si
*Tellurium containing sulfur sample cup (QC4012): measure CEL, C after spheroidization; Si
*Spheroidization rate sample cup (QC4050): Determine the spheroidization rate of ductile iron
