Modern gas quenching technology achieves high performance and satisfaction in the heat treat industry. Low pressure carburizing (LPC) furnaces in particular require thorough validation of the gas quenching process to meet metallurgical and distortion requirements. This presentation will share some specifics on a new process to validate gas quenching parameters utilizing specialized simulation software. These programs can allow for faster and more in depth analysis of gas quench parameters such as the relationship between cooling rate, pressure, and turbine speeds, and how those parameters can affect distortion by interacting directly with the part as well as the heat treat fixtures. We will demonstrate these benefits through actual examples utilizing existing equipment and parts, and showing how the data retrieved from the simulation can be implemented to optimize the quench process in the real world. The target of continuing to develop this specialized simulation software is to have a better understanding of thermal interactions during the quench without the cumbersome process of running months of tests using thermal loggers and dummy loads.
