TOPMelt Quality Control > SGR-WIN

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

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

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.

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.
