FAQ About the Carbon Cup

The importance of the thermal analysis carbon cups in the production process of iron cannot be ignored. Come learn more about Thermal Analysis Cups.

What is carbon cups?

The carbon cups are used to determine the chemical composition of cast iron by thermal analysis in the production of cast iron. The thermal analysis cups are used matching with the carbon and sulphur analyzer to quickly analyze carbon content, silicon content, and carbon equivalent in molten iron, which can redeem the smelting time of molten iron, and greatly reduce the production cycle of white and grey cast iron and therefore increase production efficiency.

What is the application of carbon cups?

The expendable carbon cup is for determining the Carbon equivalent, % Carbon and % Silicon in gray, malleable, and ductile iron by using the principle of thermal analysis.

What is the Advantages of Carbon Cups?

It is a very high success rate. It can be used with base iron prior to magnesium treatment and is well-matched with any thermal analysis system. Assurance of complete white iron solidification. It improves the casting process control and provides uniform cooling curve. It has high accuracy of the content of Carbon, Silicon and the fast thermocouple response precisely measuring the temperature of melting iron.

What is the material made of carbon cups?

The carbon cups are made of a consumable casting auxiliary material made of the cup body and resin sand.
