The Round sampling cups are used matching with the carbon and sulfur analyzer to quickly analyze carbon content, silicon content, and carbon equivalent in molten iron.
inquiryThe thermal analysis sampling cup is made of resin-coated sand, straight quartz tube, T1 and T2 thermocouple wires, sealing cement, and other components.
When the molten iron is poured into the sample cup, the molten iron gradually solidifies with time. The thermal analysis measures and calculates the CEL, C, Si, and other components according to the temperature platform of the cooling curve.
The collection of temperature curves is conducted by the microprocessor. Contents of carbon and silicon and quality of molten iron can be calculated by the crystallization process of molten iron
Cup-CE without tellurium; is used for the “Carbon Equivalent” determination of cast iron.
Cup-C with tellurium reliable data for thermal analysis to read CE, C & Si of cast iron.
Cup-HC is specially used for the determination of high carbon equivalent of cast iron / S.G. Iron.

One: option of the instrument and electric furnace
Be sure to select the specific carbon silicon analyzer and hot metal within the specified test furnace. the replacement of components when the next test furnace hot metal will be changed.
Two: data testing methods
Example: Thermal analysis of the test sample cup should be 3 to 5 consecutive (arrange it according to the time), e.g. the test result of Si% is 1.80%, 1.82%, 1.86%, 1.88%, 1.90%. Testing is completed record data.
Three: analysis
Stability. According to the above testing result, the highest one is 1.80%, the lowest one is 1.70%, the fluctuation gap is 0.1, the average value is 1.75% (±0.05).
Instrument adjustment.
If the chemical analysis of Si% molten iron content was 1.85% when the original apparatus should be set based on the si values of 0.1 and then raised to complete the adjustment (if the former setting of Si is -0,2, should change at -0.1). when tested again, the content of Si% will become 1.85%, the adjustment is over, can work now.
Four: attention
1. the hot metal temperature in the sample cup should not exceed 1350 ℃.
2. Optimum temperature of ductile iron is 1200 ℃ ~ 1250 ℃.
3. Optimum temperature of Gray Iron 250, 300 is 1250 ℃ ~ 1350 ℃
4. The abnormal situation like low carbon high silicon hot metal composition will cause instruments to measure the normal C% and Si% no data.
