BOGIE HEARTH FURNACE

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.

Our standard bogie hearth furnaces can go up to 1500°C, however any special requirements beyond this can also be taken up with a custom design. 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. Controlled cooling furnace option is also available.

BELL FURNACE

Traditionally for many decades and even today, international bell furnace manufacturers deploy continuous purging of cracked ammonia, throughout the annealing cycle, to avoid decarburisation. This being an expensive process, involving not only consumable costs like ammonia, cracker catalysts etc, but also this involves a good amount of instrumentation associated with the system including expensive maintenance.

Precons, by its innovative technology, has successfully developed cracked hydro carbon gas purging system, only for a few hours as against continuous purging of cracked ammonia, thus cutting down enormous expenditure in each cycle and practically nil maintenance achieving almost nil decarburisation, after annealing.

Each bell furnace installation comes with state of the art temperature and Thyristor control systems and user friendly PLC and Scada display panels. We bring forth an excellent collection of Bell Furnace. Our given bell furnace is manufactured from the top notch factor inputs and cutting edge technology in order to meet the international quality standards.

    Salt Bath Furnace

    Electrically heated salt bath crucible furnaces for uniform and fast heat treatment of work pieces and tools under exclusion of air.

  • Max Temp – 1000 °C
  • Custom-built for customers’ applications and requirements
  • Proven and reliable in rough production use due to strong and robust construction
  • Low energy consumption, low operation costs due to high-quality thermal insulation
  • Heating elements wound on ceramic tubes; Uniform heating of salt bath

  • A Salt Bath is a largely overlooked alternative to many types of furnace. It has many advantages and a few disadvantages over conventional atmosphere furnace. The heating medium of a salt bath is the salt itself. This is heated to the required temperature by either external heating, over the side submerged elements, or submerged electrodes. When a load is submerged into the salt it is heated rapidly and uniformly to the required temperature. The salt also doubles as a protective atmosphere during the heating cycle. When the load is withdrawn a thin covering film of salt will protect it.

    Temperatures available can range from around 1500c to 13000c. The low temperature ranges can be heated by external heating to a salt pot, or over the side submerged sheathed wire elements. Above 6000c, over the side submerge elements suffer severely from corrosion at the salt-air interface (where the elements/electrode enter the salt). At these temperatures and above we recommend totally submerged electrodes, which enter the bath through the side-wall (below the salt-air interface) and apply heat by using the salt itself as the resistance element. This method has many advantages over any heating method that enters the bath over the side wall. Not only does it eliminate the electrode corrosion at the salt-air interface, but also reduces the top losses (heat escaping from the top of the bath) because the bath can be smaller. It also aids salt circulation and agitation due to electro-dynamic forces.

    Some processes will require other equipment to complement the Salt Bath.

  • Preheating at: 700°C
  • Medium heat at: 1000°C
  • High heat at: 1250°C
  • Tempering at: 500°C
  • Application: tools heat treatment
