Product Introduction

Thermal analysis sample cup is a consumption sensor used by the thermal analyzer to measure the quality of molten iron. The requirements for high-quality thermal analysis sample cups are: the thermal capacity and thermal conductivity of each batch of thermal analysis sample cups are consistent, the thermal inertia of the sensor is low, and the phase change temperature measurement accuracy is high. The simple method of evaluating thermal analysis sample cups is: conduct continuous measurements under the same temperature, composition, incubation, deterioration and other conditions, and compare the deviation distribution of the phase transition temperature between each thermal analysis sample cup. The smaller the deviation distribution, the better the quality of the sample cup.

The KD-W type thermal analysis sample cup adopts a reasonable and reliable cup body design to ensure that the polarity is correctly connected to the thermal analyzer connector accurately; the vertical special glass protective tube design makes the cooling curve with faster response speed, wide casting temperature range, good repeatability and strong stability, and extremely high measurement rate.

The Thermal Analysis Sample Cup is a precision-engineered, single-use device designed for rapid thermal analysis of molten iron. It is  used in foundries and metallurgical laboratories widely to determine carbon content, silicon content, and carbon equivalent (CE) in molten cast iron. This sampling cup, when paired with a thermal analysis instrument, enables operators to optimize metallurgical quality in real-time, reducing casting defects and improving production efficiency.
