Thermoanalysis sample cup

Sample cup

A series of consumable thermal analysis sample cups, which are composed of reasonably designed sample cups, K-type thermocouples, etc. Thermal analysis is due to the simple determination and calculation of CEL, C, Si and other component parameters.

1. Carbon equivalent CEL

◆ Expressed by the formula CEL%=C%+Si/3%, the captured liquidus temperature is directly related to this value when the molten iron sample has just begun to solidify.

2. Features:

◆ Reasonable sample cup design, correctly connected with thermal analysis connector

◆ Vertical glass protection tube design, so that the response speed is fast

◆ Wide range of pouring temperature

◆ Good repeatability and stability

◆ High yield rate

3. In addition, thermal analysis can also be applied to the following three aspects:

◆ Pregnancy table control, through the determination of eutectic supercooling, control the gestation.

◆ Predict the mechanical and physical properties of molten iron by measuring the liquid phase temperature and supercooling.

◆ The calculation of nodularity is based on the principle of relative thermal conductivity, which can calculate the nodularity of ductile iron molten iron.

Fourth, the model and its application:

◆ Tellurium sample cup (KD-WQ): Determination of CEL and supercooling

◆ Tellurium sample cup (KD-W): determination of CEL, C, Si
