We Find the Right Furnace for You
CEC Annealing furnaces cover a broad range of Steel and Aluminum applications including tempering, normalizing, and aging, and similar automated loading, unloading and natural or forced cooling is possible with roller hearth, tip-up or batch arrangements. More steel applications can be seen under “related information” below.
The annealing process will soften the raw material, making it more flexible for use in coiling and other applications where flexibility is needed. The actual process of annealing requires that the metal be heated above the transformation point and then left to cool slowly. The exact temperature needed and the time will vary based on the type of metal being used. CEC's precision furnaces make sure that you get consistent temperatures and times on every batch. As a leader in annealing furnace design, CEC offers the most advanced options in annealing furnaces. CEC has produced annealing furnaces for some of the biggest manufacturers from around the world.

CEC has developed a computer program to predict coil heat up and cooling.
The self-cleaning cooling coils built into CEC annealing furnaces have many benefits.
1. Reduction in cooling time since each furnace internal circulation fan has finned cooling coils built around it that add significant surface area for heat transfer compared to external cooling coils.
2. Less connected horsepower due to elimination of external cooling fan that is necessary with external cooling coils.
3. No external ducts and no dampers needed as with external coils to close/open the cooling ducts.
4. Less floor space requirements due to elimination of external cooling fan, ductwork and external water cooling coils.
5. Less chance for air leaks into the furnace dues to elimination of external cooling fans and cooling ducts which can leak due to expansion/contraction at every cycle.
6. Less operating horsepower due to shorter cycle time.
7. Cooling can be controlled for each zone of control similar to heating control.
8. Self-cleaning of cooling coils internals by initial steam generation at start of cooling cycle. For external coils they are cold at start of the cooling cycle and do not have this automatic internal cleaning.
9. Coil surface exposed to heating on the outer surface since inside the furnace. This burns out any residue on coil outer surface. External coils get clogged and have to be cleaned due to build-up that reduces the cooling performance.
