Thermal analysis sampling cup

● The square sampling 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 shape.500 degree Celsius 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 degree Celsius, the cup is formed by the resin bond. This cup is coated inside with silica for being thermal insulation and then filled in the cup with 15 gram of Tellurium. By means of drying this coated cup at the temperature of 80 degree Celsius for 4 hours, the carbon cup is ready for the casting control.

● The Round sampling cups are used matching with the carbon and sulphur analyzer to quickly analyze carbon content, silicon content and carbon equivalent in molten iron.The carbon cup is made of resin coated sand, straight quartz tube, T1 and T2 thermocouple wires and 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.
