Bogie Hearth Furnace

Product Details:

We are involved in Gas Fired Bogie Hearth Furnace for any charge weights. The heating of Bogie Hearth Furnace could Electric, Gas or HSD. The Bogie Hearth Furnace for all above applications. Furnace can be offered with single bogie or double bogie, with motorized rack and pinion drive system, motorized or pneumatic door operation, effective sealing arrangement etc. The heating could be gas or liquid fuel fired including high velocity burners. We can also offer radiant tube fuel firing for special applications.

Product Details:

When parts or charges that are to be loaded onto a furnace are heavy and require material handling facility for loading and unloading, a moving bogie or hearth is provided to make this easier. Once the hearth moves out of the furnace heating chamber parts can be loaded by means of an electrical overhead crane (EOT), gantry system or mobile crane / forklift mechanism. If required, special charge loading mechanisms can also be provided based on the user’s job profile, lack of material handling facility or overhead space constraint. The bogie movement is motorized for easy handling. Similarly the door movement would be with motorized gear drives or hydraulically / pneumatically actuated.

High temperature applications include sintering, hardening, annealing and normalizing whereas lower temperature applications include tempering and stress relieving. The control system is provided with options to set and control the ramping rate, soaking rate and cooling rate depending on the process cycle, the option of PLC based control is also available. The furnace can be used in open atmosphere or controlled atmosphere as per application. We provide designs with in and out bogie (hearth) movement as well as through and through double door bogie movement if required for an assembly line or process line.

The mode of heating can be via electrical heaters, gas fired or oil fired burners as per the user’s requirement.The furnaces of J R Furnace are energy efficient achieved by efficient sealing to prevent undue heat losses and thyristor power controls to limit current consumption. Design factors also ensure excellent temperature uniformity throughout the heating chamber so that parts are universally and evenly subjected to process parameters and heating cycles.

Product Details:

Components such as welded structures, cold drawn or formed items require stress relieving as stresses are induced in these processes which will deform the components after they are put in use. Our bogie hearth furnaces for stress relieving or stress relief annealing are available with standard configuration as well as configurations custom for the user’s job profile and volume. For higher temperatures, the design is based on radiation heat transfer without air circulation.
