1. Product Introduction

The series of consumable furnace pre-fixed carbon sample cups are composed of a proper designed cup body, K-shaped paired wire, special glass protective tube, etc. Thermal analyzer is easy to measure and calculate the components parameters such as CE, C, Si.

The Quick Analysis Cup is a specialized sampling tool used in the metallurgical industry to  analyze the chemical composition and carbon-silicon content of molten iron rapidly. Designed for using with thermal analysis instruments, this disposable cup allows for quick, accurate, and reliable quality control during the iron casting process. With its integrated thermocouple and high-temperature-resistant construction, the Quick Analysis Cup is essential for foundries seeking real-time process optimization and metallurgical consistency.

2. Carbon equivalent CE

When the molten iron sample begins to solidify, the captured liquid phase temperature is  related to this value directly.

3. Features

Reasonable cup body design, firmly connected to the thermal analysis connector

Vertical glass protective tube design makes the response speed fast

Wide pouring temperature range

Good repeatability and stable

High test rate

4. In addition, the following three aspects can be applied to thermal analysis

The pregnancy control is controlled by the determination of eutectic supercooling degree.

By measuring the liquid phase temperature and supercooling degree, the mechanical and physical properties of molten iron are predicted.

The calculation of spheroidization rate can be calculated based on the principle of relative thermal conductivity.

5. Model and its application

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

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