Specification :

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.
