GERMAN Roller Hearth Furnace
Our roller hearth furnaces are designed for the heat treatment of rods, tubes and profiles both in continuous operation or batch operation at high temperature uniformity and low energy consumption. High heating and cooling rates can be realized due to powerful and highly efficient convection nozzle systems. Our plants are suitable for copper, brass, aluminum and steel.
Annealing atmosphere: air, protective gas. Roller hearth furnaces which are only operated with air can be easily maintained due to a separated furnace housing which is equipped with a lifting device for the upper part.
