Approximately 20,000 foundries worldwide produce cast iron. The exact chemical composition of the alloy being manufactured needs to be checked throughout the melt process to ensure the quality of the finished product meets specification. OES technology is primed to deliver accurate and reliable one-step quality control throughout the process. A Hitachi High-Tech Application representative will explain how this can be achieved.

The guide for foundries about how to achieve optimal melt control in cast iron with OES spark spectrometers covers:

• The challenges of cast iron analysis
• The secret of perfect OES carbon analysis: sample prep
• Understanding calibration and type standardization
• Maintaining your OES analyzer
• Identifying the grade
• Making process control audits safe
• Making spark OES your first choice
