Annealing of grey-iron castings
Bogie-hearth furnaces for annealing of grey-iron castings can run on electricity (up to 1280 °C) and on gas (up to 1400 °C). For furnaces with operating temperatures of up to 850 °C, there is also forced circulation for ensuring transfer of heat into the charge. The furnace’s design can either be chamber or bogie-hearth chamber, with this choice usually depending on how the charge is manipulated. Thanks to their sturdy construction, these furnaces are ideal even for heavy operations.
We designed the VKTP 20000/11 furnace in particular as a gas furnace with recuperation, which saves considerable operating costs for its owner. Thanks to the placement of the burners, we have achieved a fantastically even temperature distribution in the furnace’s operational space. This device also has the indubitable advantage of being easy to operate via its touch panel and programmable PLC automated system.
We have also supplied similar systems for annealing parts of the undercarriages of railway vehicles and other rail vehicles, and for annealing radiator and heating element components.
