JR FURNACE offers a full range of Aluminium Coil/Foil Annealing Furnaces up to a capacity of 80 MT batch to the aluminium industries. These furnaces will be Electrically Heated or Gas Fired and the design will be either Fixed Hearth or Bogie Hearth type to suit customer’s requirement. Aluminium coils/foils placed on the charge carrier can be loaded into the fixed hearth furnace by a hydraulically/electro-mechanically driven charging machine or can be loaded on the bogie with the help of an EOT crane for bogie hearth furnace. After the annealing cycle is completed the foils/coils are discharged from the furnace with the help of a discharging machine from the fixed hearth furnace or unloaded from the bogie hearth furnace with the help of the EOT crane.
The foils/coils will be indirectly heated through radiant tube burners located behind stainless steel baffles and are provided with suitable recirculation fans for better heat transfer through convection and good temperature uniformity.
Hot air recirculation inside the furnace is done by an efficient axial or centrifugal type recirculation fan, which can be with a two-speed motor or with the VFD drive for low power consumption. Stainless steel baffle for proper hot air circulation inside the furnace is provided. Forced air-cooling arrangement with the help of centrifugal fans can be offered.
