PhoenixTM LLC received an order from a major Detroit-based auto manufacturer for a hot-box system to be used for carrying out furnace surveys to AMS 2750E in a multi-chamber, low-pressure carburizing furnace. The system has been engineered to occupy less than one-third of the volume of the product basket to maximize the accuracy of the survey. The system will be equipped with RF telemetry so that the survey can be managed from outside the furnace and quench deflectors to allow product profiling through the gas quench.
