In cast iron and SG iron foundries, OES is primarily used for melt shop control. The goal is simple but critical: ensure that every heat has the correct chemistry before pouring, so that the final casting achieves the desired microstructure, strength, and machinability. Even small chemistry deviations can result in scrap, re-melts, or downstream quality issues.

Foundries typically monitor carbon, silicon, manganese, magnesium (for ductile iron), phosphorus, sulphur, and residual elements. Speed of analysis is extremely important in this environment, as decisions often need to be made quickly while metal is still in the furnace. Operators also value ease of use and consistency, especially across shifts.

For foundry applications, customers look for an OES system that delivers fast, repeatable results under harsh conditions, without frequent recalibration. Gold Plus X is well suited for foundry melt control where tighter chemistry control is needed, while Silver Plus can comfortably support routine foundry quality assurance applications. If the highest level of accuracy and precision is required, Gold Plus XL may be selected as the preferred option.
