Practical Implementation with Turn-Key Solutions

Initial reviews of the published literature will reveal various approaches to addressing how to investigate inclusion composition and target their potential influence on the process. Specific details about the effects of calcium treatment, the formation of spinel inclusions and their effects in aluminum killed steels, and potential sources of nozzle clogging have been thoroughly investigated. In essence there is significant information on how to study inclusions but not how best to continuously monitor and maintain their formation.

Most EDS based analyzers are found in research laboratories and not at the production floor largely to their inability to handle adverse environments. In addition, the skill set of the operators need to be such that they are SEM and EDS experts. The MQA™ relies on turn-key solutions to provide the customized information you desire.

The first step towards implementation is to establish sampling and preparation protocols. Once these are established, a standard analysis protocol can be put in place and evaluated to determine the optimal analysis parameters, the performance metrics and capabilities of the system to monitor the process. The resulting methodology was then utilized to determine the current capabilities of the plants practices and used to optimize the process.

Once an understanding of the general inclusion types being generated was established, a streamlined-database system was developed to monitor the process which could ultimately be used to determine when the process was in-control or out-of-control. The approach also follows the general statistical based process improvement programs currently being utilized throughout the industry.
