In applications at high temperatures combined with high throughput rates, Walking Beam Furnaces come into action. The parts lying on charge carriers are run through the furnace. The walking beam is a transport vehicle of utmost smoothness. Thus, the walking beam furnace combines the advantages of roller furnaces with those of pusher furnaces. It is highly accepted for Fe-PM parts sintering, MIM, and even refractory and heavy metals and fuel element sintering.
Frequently, different furnace approaches are combined: stearate zone = pusher furnace, HT zone = walking beam, rapid cooling = roller furnace, cooling zone = conveyor belt furnace. This way, a highly efficient high temperature sinter furnace for Fe-PM is modelled.
