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

• 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 When the load is withdrawn a thin covering film of salt will protect it.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.

J.R. Furnace and Ovens (P) Ltd have made remarkable recognition in the market for its excellent quality Salt Bath Furnace & industrial ovens.

Bell furnace are commonly used for intermittent or batch processes.

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. Our offered Rectangular bell furnace is accessible in numerous specifications as per the variegated needs of customers. As well, our valuable customers can avail this bell furnace from us at industry leading rates in a given time frame.

Rectangular Bell Furnace Features:

• Easy to operate
• Hassle-free performance
• Maintenance free

Our firm specializes in providing Aluminum Coil Annealing Furnace to our prestigious clients with the latest technology and high-quality material as per the set norms of the industry.

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.

Product Details:

Bell Annealing Furnace brings in excellent temperature uniformity, consistent quality and good production rates. Bell Furnace is suitable for black, bright and spherodized annealing of steel coils, non-ferrous strips, wires and general heat treatment processes up to 1100°C. Bright annealing of cold-rolled steel strip coils and heat treatment of medium and thick hot-rolled plate, long products and wire coils are done using a bell-type furnace.

Type of furnace is usually rectangular or cylindrical form, single or multi-stack gas or electrically heated. Continuous purging of ammonia is deployed throughout the annealing cycle to avoid decarburizing. Overhead crane is used to load the base and move the equipment. Coils are tilted to the right position and placed on the annealing base.

The convection and heat transfer occurs in the base assembly. Forced atmosphere circulation is used with the help of radial fans for temperature up to 950°C to improve convection. The cooling happens when the furnace is removed with inner cover acting as a protective atmosphere. In both strip annealing and wire annealing, the convection flow goes up on the sides and down the centre.This type of furnace is widely used for the following applications such as:

• Spherodised Annealing of Steel Wire Rod Coils
• Soft Annealing of Steel Wire Rod Coils
• Black and Bright Annealing of Steel Strips.
• Normalising/ Stress Reliving Of Steel Castings.
• Annealing Of Copper And Aluminum Products.
• Decarburising Of Stampings.

 

Salient Features:

• Atmosphere : Liquid : Hydrocarbon & ultra pure nitrogen with automatic pressure control
• Option: Vacuum & nitrogen atmosphere.C
• State of the art technology combined with low cost production to achieve Spheroidisation between 85% to 100% & almost achieving zero decarb.
• Unique Hydro Carbon combustion system working in total auto mode system only for a very few hours (less than 2 hours ) to achieve the above specified Spheroidisation & decarb level .
• Multi profile programme controller with ratio control system to achieve close temperature uniformity.
• Auto programming facilities to adapt different cycles depending upon diameter – grade combination.
• Provision for data logging.
