TES Square Carbon Cup With Te

The square carbon cup is for determining the Carbon equivalent, % Carbon, and % Silicon in molten iron by using the principle of thermal analysis. Cups are available in square and round shapes. 500 ℃ to produce “resin bonded sand”. This resin-bonded sand is shot into the pre-heated mold with having the K-type thermocouple tube inside. At the temperature of 250 ℃, the cup is formed by the resin bond.


This carbon cup is coated inside with silica for being thermal insulation and then filled in the cup with 15 grams of Tellurium. By means of drying this coated cup at the temperature of 80℃ for 4 hours, the carbon cup is ready for the casting control.

Product Features:

Carbon cups are Tellurium coated sensors used for the determination of carbon equivalent, % Carbon, and % silicon in gray, malleable, and ductile iron. They cover the entire range from 2.5 to 5 CE.
1. Very high success rate. Dependable.
2. Very high accuracy of Carbon and Silicon.
3. Wide pouring temperature range

Application of Carbon Cup:

The expendable carbon cup (thermal analysis cup) is for determining the Carbon equivalent, % Carbon, and % Silicon in molten iron by using the principle of thermal analysis. The advantages of this carbon cup are as follows:
1. With Tellurium grain, the complete white iron solidification can be met
2. Fast thermocouple response
3. Precisely measuring the temperature of melting iron sample
4. Provide uniform cooling curve
5. High accuracy of the content of Carbon and Silicon
6. Improve the casting process control
