Premixing Grain

Granulation or premixing of karated grain is highly recommended.

The advantages of premixing are:

  1. Lower melt temperature when casting
     
  2. Lower melt losses
     
  3. More consistent melt time
     
  4. Better mixture of metal

Even though premixing is not essential, it allows a greater consistency in casting. By premixing, superheat temperatures are not needed in the cast for proper mixing. This lowers the melt loss factor due to loss of zinc in the alloy. Loss factor should be 1/4 of I % or less, with 1/1O of 1 % possible under ideal conditions.
