PI-5 TANKS AND DRUMS ANNEALING FURNACE

Annealing tanks

Annealing after welding allows to reduce (or even to remove completely) the internal stress, allows also to improve and standardize the material structure and also to better mechanical properties. Annealing through releasing process is used to remove stresses resulted from welding and mechanical stresses resulted from the deformation of the elements. Annealing through tempering is used to eliminate the martensitic structure in the weld. Normalizing annealing is used to reconstruct and to standardize the structure. The joints after normalizing are characterised by the high yield while maintaining high strength.

Description of the process

1. Placing an item on a trolley carriage. 2. The entrance of the truck tank to the furnace. 3. Placing an item by using boosters at the

supports of the furnace. 4. The exit of the trolley out of the furnace. 5. Starting the heat-treatment.
