FURNACES AND AUTOCLAVES
MESH BELT FURNACES
We offer continuous mesh belt furnaces with a maximum operating temperature of 1,100 °C, suitable for a wide range of heat treatment applications such as hardening, annealing, tempering and stress relieving. The furnaces can be designed for single or multi-zone operation, and water-cooled zones are also available. Each mesh belt furnace can be supplied to operate with inert gas or reactive gas atmospheres with O2 control and AMS 2750G compliance. The number of controlled heating and cooling zones, zone length, belt width and type of atmosphere control can be specified to meet individual customer needs. This furnace can be supplied with additional modules:
VRRC SINTER HARDENING MODULE
The separate process step of conventional heat treatment of PM parts can be eliminated in several cases by the SINTER HARDENING process which takes place in a module installed immediately downstream of the sintering furnace, before the water jacket cooling sections. The furnace atmosphere is recirculated through a heat exchanger and affects the parts as they emerge from the sintering furnace.
ACCELERATED COOLING MODULE
The length of the water-jacketed cooling section can be reduced by using an accelerated cooling section placed at the rear of the furnace where the cooling rate is slow.
WALKING BEAM FURNACES
They are compact, high performance furnaces with low operating costs handling a maximum temperature of 1,450 °C with process capabilities for sintering ferrous, non-ferrous, ceramic, hard metal, MIM and stainless steel parts and powder annealing. With the ability to stack multiple layers of parts on top of each other, atmospheric gas locks at both ends between the debinding and sintering sections improve furnace gas quality and help to significantly reduce gas usage compared to open-ended furnaces. Trays are carried on raised alumina blocks, which ensure a high degree of temperature uniformity in the hot zone cross-section. These furnaces primarily work with N2, H₂, and N2 + H₂ atmospheres (with or without humidification) or in air. Automated loading and unloading (including tray return), heavy-duty mechanism for up to 2000 kg/m2 (400 lbs/ft2) hearth loading, multiple gas injection ports, multipoint gas sampling, safety monitoring of pressure, gas and water flow, SCADA control systems.
VACUUM PRESSURE FURNACES
/ AUTOCLAVES
In TAV VACUUM FURNACES we supply furnaces for applications in vacuum heat treatment, vacuum brazing, vacuum sintering, advanced ceramics, diffusion brazing, aluminising and UHV (Ultra High Vacuum). With three possible configurations, the models available present advantages for each application.
HORIZONTAL VACUUM FURNACE WITH HINGED DOOR
In response to rapidly changing market requirements, it is the best solution to heat treatment needs in various vacuum application fields. Wherever speed, compactness, precision and reliability are required, this vacuum furnace offers customers the most appropriate answer in terms of automation and operational flexibility. This configuration enables quick and easy loading of various volumes giving you the flexibility you need in a variety of R&D and production applications.
HORIZONTAL VACUUM FURNACE WITH CART BOTTOM DOOR
For applications requiring higher repeatability and reproducibility of results, the horizontal vacuum furnace with a cart bottom door is the most cost-effective solution for large and dense loads. It is a highly functional system for heat treatments (hardening and tempering, ageing, stress relieving, solution treatment, annealing) as well as for brazing and diffusion bonding which can move massive loads up to several hundred kilograms with utmost safety.
VERTICAL VACUUM FURNACE
Vertical furnaces provide a precise solution for components with tall structures to be heat-treated as they ensure homogeneous temperature distribution including in complex geometries and at very high load densities. The system is arranged for either top-loading or bottom-loading to better meet your needs. The system’s vertical design means a small footprint which saves valuable floor space in the plant.
