Can the increased temperature variability in my annealing furnace be causing the ductility variations in my product?


Jake Fotopoulos
Lead Process Controls Engineer

It depends on the amount and location of the variability. Variability in the critical annealing parameters—temperature, dew point and atmosphere compositions—can have a dramatic impact on product quality. To help find the source of the variability, record the critical process parameters during production—larger than normal deviations in temperature can affect grain growth, hardness and ductility. Then you can correlate poor quality runs to data trends and identify what may be causing the change in properties.

Installing a process control system to monitor and control these variables can help you reduce variability. A small investment in control technology can provide a large return in reduced production costs and improved quality. Our commercial engineers and extensive experience in process controls can help you improve your process consistency and save money.
