* Tube Reduction Furnaces are widely utilized to reduce tungsten oxides or Mo oxides in Hydrogen atmosphere at elevated temperatures.

* It adopts heat resistant stainless steel as muffle material. Muffle cross section is a rector square.

* It is convenient to exchange heat elements and maintain the furnace.

* It can either be pneumatically pushed or electrically pushed.

* Every sector has its independent temperature control system including thermal couples, intellectual digital PID adjustor and SCR to ensure precise control of temperature By special design; working temperature of tube reduction furnaces can be extended to as nigh as 1050C~1100C, which make if possible to produce coarser tungsten powder with pa-ticle size over 18 Mrcro meter.
