CE Sample Cup

Product Introduction

CE sample cups are mainly used in the casting industry, used to conduct thermal analysis of white tinplate, gray cast iron, ductile iron, etc., connected to supporting instruments,  measure and calculate carbon equivalent CEL, carbon content C, silicon content Si and other components. It is mainly composed of cup body, K-shaped wire, special glass tube, etc.

The CE Sample Cup is a specialized thermal analysis tool used to  measure the Carbon Equivalent (CE) of molten cast iron quickly and accurately. Designed for using in conjunction with thermal analysis instruments, this single-use sample cup helps foundries control the carbon and silicon content of molten iron in real time. The CE value is a critical parameter for ensuring consistent casting structure, mechanical properties, and overall product quality.

Features

1. Reasonable and reliable cup design to ensure that polarity is  connected to the thermal analysis connector correctly;

2. The vertical special glass protective tube design makes the response speed faster;

3. Wide pouring temperature range;

4. Cooling curve with good repeatability and strong stability;

5. Extremely high measurement rate.

Accuracy meter requirements

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

Model and its application:

Tellurium-free cup (KD-FQ): CE, SG%, supercooling

Tellurium-containing cup (KD-F): CEL, C%, Si%
