raditionally 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.Thermal Technologies, 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 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.

DBQ or drop bottom quench solution treatment furnace is primarily used for solutionizing of aluminium parts prior to forming. The requirement is a quick quenching of aluminium parts usually within 5 to 10 seconds so that the material comes to ideal precipitation hardened condition. When heated evenly to a temperature of upto 550C, a solid solution of copper is formed in the aluminium structure which flows throughout the microstructure. The furnace is inverted type with charge lifting and lowering facility to accommodate the high speed quenching including de-clamping, door opening and quenching. The furnace can be stand alone type with charge carrier loader and quenching tank moving on the floor or floor mounted with charge carrier loader and quench tanks sliding in a pit. As the requirement is very fast quenching it is fully automated by the use of PLC and SCADA. These furnaces can also be used for continuous ageing cycle ranging from 16 24 hrs time. Various quench media such as water, glycol or other polymer oils as per process requirement are used. Area of application is generally used in aeronautical industries for solutioninzing and ageing of structural parts, also in forging industries of aluminium alloy forgings.

Our company has earned great laurels with Sealed Quench Furnace. A sand-tray beneath where molten metal is poured contains any spillage. There are tiles which are situated around the work chamber. It consists of a casting facility, in which metal is melted in a pot inside a furnace, before being poured into a mould, usually constructed from sand.

Made available to clients at the most reasonable rate possible, the offered range of Pit Type Furnace is known to be one of the finest that are available in the market. Making of this range is done as per the set industry norms and guidelines, utilizing the finest raw materials and modern machines. Owing to this, the product is known to have its quality maintained and a superior performance and longer service life.

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 users 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 1500C, 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 Etc.

Pit type sealed retort furnaces are of a cylindrical design vertically erected with a positive sealing mechanism on top in order to contain and preserve heat and atmosphere during a process cycle. The job or charge is loaded into a retort which functions as the chamber of the furnace and the retort is heated externally electrically. Pit furnaces like these are used in process industries like coal tar processing, separation of titanium and magnesium from ore, and in general engineering and metallurgical applications for carburizing, nitriding, carbonitriding and nitrocarburizing as well as hardening, tempering, annealing etc. . Special processes such as aluminium and titanium heat treatment can also be done. In process industries these furnaces can also be used in high pressure applications with temperatures from 800C to 1200C and pressure ranging from 400mm water column to 9 bar. These are often laid in a pit to make most of the space available and charges can be loaded and unloaded easily. These are manufactured considering working controlled atmospheres with inlets for diffusion and distribution of cracked ammonia, hydrogen, LPG, methanol, argon, nitrogen and other process fluids. Thermal Technologies manufactures and sets up complete automated process plants also. Temperature control, fluid dissociation, gas penetration and dosing can all be taken up for automated operation.
