Case Study
Case study: Annealing and Stress Relief Oven
Ceramicx supplied three conveyor tunnel ovens to a customer in the U.S. packaging sector. Ceramicx ceramic emitters paired with closed loop feedback systems meant that these ovens integrated seamlessly with the customer existing machinery. The conveyors employed are variable speed with 2-way drive and used a stainless steel belt system.
The conveyor length was specified by the customer but Ceramicx chose the belt material and specification that was heat resistant. Perforated aluminium was used for the back cover to allow ventilation in the wiring area. FTE and HTE type ceramic elements were used to achieve consistent heat across all of the designated heating area.
The conveyor oven sizes are as follows –
45 kW oven – 30 ft conveyor with a 10 ft oven + control system.
45 kW oven – 30 ft conveyor with a 10 ft oven + control system.
67.5 kW oven – 42 ft conveyor with a 15 ft oven + control system.
