Method for doping paraffin forming agent in cemented carbide mixture

The invention discloses a method for doping a paraffin forming agent in a cemented carbide mixture. The method comprises the following steps of: melting solid paraffin into fused mass; heating a cemented carbide wet-grinding mixture to be at a temperature higher than the melting point temperature of the paraffin; adding melted paraffin to the cemented carbide wet-grinding mixture; continuously heating and stirring the cemented carbide wet-grinding mixture; and screening and granulating the cemented carbide wet-grinding mixture according to a general method when the cemented carbide wet-grinding mixture reaches a drying requirement so as to obtain a qualified cemented carbide mixture. The method integrates and finishes the steps of drying the cemented carbide wet-grinding mixture and adding the paraffin and evenly stirring in a link and equipment by utilizing the characteristics that the cemented carbide mixture contains alcohol, and the paraffin is dissolved in the alcohol at a temperature higher than the melting point temperature, can dissolve the paraffin without adopting a gasoline or another solvent, avoid mixing impurities in the solvent and has the advantages of decreased production cost, simple process, small equipment investment, simple operation and high cemented carbide wet-grinding mixture quality.
