Pusher furnaces and kilns up to 2,500°F (1,400°C)

Pusher Furnaces utilize the sequential pushing of carriers through the system by a ram from one end. Higher process temperatures (up to 2,500°F / 1,400°C) than on belt furnace are typical.

The system allows the use of sealed end vestibules to control the atmoshere inside the furnace. A special class of small format pusher furnace uses a ceramic muffle, usually a round or D tube with  Molybdenum or platinum wire wound around the outside.
