The Recycling of Tungsten Carbide

Brief description of this technology:  
The present invention relates to the method of containing iron or tungsten powder or the powder aggregation .This invenition includes  these following steps:


At the begining,  we can mix powder containing tungsten carbide at least one first powder level with powder containing the iron oxide or tungsten oxide-containing powder and  any kind of  iron powder of at least a second powder fraction mixed ( The weight of the first fraction is 50-90% of the weight of the mixture,the weight of the second fraction is 10-50% of the weight of the mixture.)

The heating step  is the second step. The mixture should be heated up to 400-1300 ° C. The perferred temperature of the mixture is 1000-1200 ℃. The present invention also relates to the iron powder, tungsten powder and power aggregates.
