Horizontal atmosphere furnace HAF type
Horizontal atmosphere furnace HAF type
The horizontal atmosphere furnace with moveable hearth is prepared to work in temperature max 1150°C in air atmosphere. Batch loading/unloading is fully automated. As a optional equipment the furnace can consist of manual operated batch loader and batch instrumentation. The compact furnace construction doesn´t need too much room to be installed. The furnace housing is composed of carbon steel. The heating elements are placed on internal chamber walls, on ceiling and hearth. It ensures temperature uniformity in the whole heat zone. The furnace is controlled by PLC controller with written down function and auto data save on a hard disc.
Processes: tempering, annealing, hardening, normalizing.
Our series of horizontal atmosphere furnaces is available in a few types which differ in their design and application, i.e.:
- Chamber furnaces with protective or carburizing atmosphere or without atmosphere
- Car-bottom hearth furnaces with or without protective atmosphere
- Horizontal atmosphere furnaces with forced convection heating.
Working temperature depends on a the requirements of a particular heat treatment i.e.:
- quenching, carburizing: 750°C to 1300°C
- tempering, nitriding: 150°C to 750°C.
There is a choice of electric or gas heating available for horizontal atmosphere furnaces.
