A new type instrument for nodularity determination / SGR Series Windows EditionSGR-WIN

The same melt is poured into Mg-TP as well as Mg-Cup. Correlation with TP image analysis is obtained and the data is input. SG% in the basic program is automatically calibrated.

The final melt after spheroidization is poured into a Mg-Cup and nodularity is determined within only three minutes!

Experimental results suggest the following factors to be important for nodularity improvement.

• Properties of the original melt before Mg treatment.
• Performance of Mg treatment and inoculation.If eutectic solidification is above 1150° C (2102° F), improper Mg treatment and hence, insufficient nodularity may be suggested. If eutectic solidification is between 1130 and 1135° C (2066 and 2075° F), well-grown nodular graphite may generally be expected.
• Chemical composition of the melt, including carbon equivalent and minor residual elements.
• Casting section thickness.
• Pouring temperature, time before pouring, and other process variables.
