Product description
FN electric conveyor belt furnaces for chain welding, brazing and heat treatment in a deoxidising atmosphere are available with one or two heating chambers with widths ranging from mm. 70 to mm. 100 and use 70 mm and 90 mm belts.
The maximum temperature is 1000 °C, the power supply is 220/380V 50/60 Hz. It works with a mixture of hydrogen and nitrogen gases.
Furnaces with a maximum temperature of 1150 °C, special sizes and two or more conveyor belts can be built on request.
Its compact size, thanks to the use of special vacuum-formed ceramic fibre insulation materials, its original design and the possibility of combining several modules make this furnace easy to install in any work environment.
The ammonia dissociator, if required, is inserted into the base of the machine. It is equipped with a catalytic retort made of seamless Inconel 600 tubes, filled with special catalysts for maximum performance and long life.
The treatment chamber is made of Inconel, constructed and assembled with our exclusive special features to ensure dimensional stability and long life.
The double-walled cooling chamber has a safety thermal sensor to stop the conveyor belt in the event of a coolant failure.
A special automatic shut-off device intervenes in an emergency to close the deoxidising gas passage.
All models have an automatic deoxidising gas ignition device at the end of the chamber.
The electronics are controlled by a PLC: complete, precise and reliable, it ensures repeatability and consistency in the results of the various processes, protects all machine components and safeguards operator safety.
