Carbon Cups

We offer our customers a wide range of Carbon Cups. Series of expendable cartridges that determine %CE, %C, and % Si in gray, ductile and malleable irons by the thermal analisys method when used with TemCar or other similar instruments.
TheCup assures accurate measurement and excellent reproducibility with every cartridge you use.

1. Tellurium plug on the type T cartridge mixes completely with the molten iron sample, helping the formation of white iron on solidification.
2. Precise shape of cartridge and accurate positioning of thermocouple junction provide accurate, reproducible cooling curves with well defined arrest points.
3. Special high thermal shock-resistant mould prevents "leaking".
4. Gate on base of cartridge permits simple visual orientation with plug.
5. Quartz tube insulates the thermocouple wire.
6. Accurate Chromel-Alumel thermocouple is calibrated to an accuracy of +/- 1A C at 1200A C (+/-0.01 CE).
7. Thermocouple wires form electrical contacts on underside of cartidge; sufficient interference between thermocouple wire and plug contacts, together with weight of sample, create shake-proof connection between cartridge and holder contacts.
8. Guide posts on plug align cartridges for proper electrical polarity; sturdy holder supports cartridge firmly.
9. Male contacts are made of thermocouple-grade Chromel and Alumel to prevent thermo-electric errors. Pins are easily replaceable to reduce maintenance time.
