During the oil quench products within the batch can sometimes experience distortion problems, which may have several causes including flow patterns, temperature variations, etc. Monitoring the temperature at various depths within the product and locations around the batch can provide valuable data on the temperature profile of the part throughout the complete heating and cooling cycle. However, monitoring component temperature from a data logger external to the furnace is not possible, so the PhoenixTM Oil Quench system (Patent Pending GB1509136.6), which is able to travel throughout the process with the products, is the answer.
The system travels through the furnace similar to a production batch, monitoring temperatures up to 950°C at various points of the furnace for surveying the furnace, or fixed to production parts to measure core and surface temperatures.
In the subsequent oil quench the system monitors the temperatures at a sampling interval down to 0,5 sec. This provides exact data for optimizing the oil flow as well as the setup of the batch.
All data is analysed in the Thermal View software. A comprehensive set of tools allows for example the calculation of gradients or time at temperatures but also an automated CQI-9 report.
