Temperature Determination in Batch Type Furnace
The batch brazing furnace meets all the requirements of full production capacity tunnel furnaces in terms of heating rate, atmosphere purity and temperature uniformity.
The maximum size for the component to be brazed is 600 mm width x 600 mm height x 900 mm depth. The maximum heatable mass is 60 kg aluminium plus an additional 10 kg steel.
Special features such as viewing ports allow a first hand look at brazing in progress.
Temperature Monitoring System "Datapaq"
One important factor in aluminium brazing is monitoring the component temperature.
For successful brazing of heat exchangers, it is necessary to precisely maintain the temperature profile in the furnace zones during the entire brazing cycle. A uniform temperature distribution throughout all parts of the units is essential for good joint formation.
The control of temperature and time profiles during brazing can be realized by using a system (Datapaq) which records all information with eight precision thermo-couples. This heat-insulated device is passed through the brazing cycle together with the heat exchanger. Thereafter, the data is processed and transferred by a computer program.
