  • Sintering of ferrous, non ferrous, ceramic and stainless steel parts
  • Powder annealing with oxide reduction

Walking beam furnaces are compact plants capable of high throughput. This is achieved by the ability to stack several layers of parts one over the other which results in a sharp reduction of the thermal mass. Gas locks at either end help in reducing the gas consumption significantly compared to open ended furnaces. Trays are carried on raised alumina blocks that ensure a high degree of temperature uniformity across the hot zone cross section. These furnaces primarily work with N2, H2, N2 + H2 atmospheres (with or without humidification) or with air.
