Production Process
 

Preparation of raw materials - the raw material separation - mixing - reduction treatment - second mixing - pressure sintering - swaging, drawing - Finished
 
 1: raw material preparation
   Raw materials for the tungsten powder and ammonium rhenium powder, tungsten powder particle size less than 4um, ammonium rhenium size of less than 200um
 2: material separation
  Tungsten powder and ammonium rhenium powder were separated in the separator, so that agglomerated particles well dispersed
 3: Mixing
  The separation had separated tungsten powder and ammonium rhenium powder together were loaded efficient mixer mixing, mixing time 10-24 hours
 4: reduction treatment
  Mixed alloy powder under the protection of hydrogen reduction treatment. Reduction treatment in three stages:
  The first stage: the reduction temperature is 200-350 ° time 1-2h
  The second stage: the reduction temperature is 400-600 ° time 1-2h
  The third stage: the reduction temperature is 700-900 ° time 1-2h
  Processing time for each stage of the processing apparatus according to the conditions, the chamber volume, added material may be
 
    5: second mixing
   Mixing, mixing time 8-20h alloy powder after reduction by re-loading efficiency blender
    6: Pressure sintering
   The second alloy powder after mixing is compressed into billet, billet now pre-sintering time 0.4-1h, pre-sintered at a temperature of 2600-3000 ° billet at a temperature of 1100-1300 ° and hydrogen protection and hydrogen under the protection of the final incipient fusion sintering time 1-2h
    7: swaging, drawing
  Sintered billet in the swaging swaging machine processed into thin rods, thin rod drawing machine drawn into tungsten-rhenium alloy wire
    8: Finished
Packing: Each volume 400-600g, per kilogram of 250m-260m.
