| Careful attention to alloy chemistry limits is the starting point for creating a product that will manufacture consistently
both within the coil and coil-to-coil. Initially, a chemical analysis is conducted at The Miller Company’s fully robotic spectrometer.
The sample, in button form, is milled and then placed on the spark stand.
A spark is struck between the electrode and sample, generating light.
The light is diffracted, and intensities at different wavelengths are analyzed to allow alloy
composition (both major elements and impurities) to be determined with a
high degree of accuracy. The results are forwarded automatically to the casting deck where the casters review the analysis and adjust as necessary.
The casting operation is where the foundation is laid for producing the highest quality finished metal.
This is where day-to-day, week-to-week, and year-to-year the quality
consistency must be assured and where the solidification/withdrawal dynamics must be carefully matched to the alloy being produced.
The Miller Company casts its alloys on multiple horizontal continuous casters.
Over the years, Miller has incorporated numerous improvements to the casting
technology it utilizes. We believe that our casting operation is
exemplifies the most pronounced differentiation from our competition, as
it assures our customers an unparalleled freedom from defects.
