The invention relates to a forming agent of the manufacture of hard metals and the production method and the use method. The components and the weight per cents are 20 per cent to 27 per cent of paraffin, 34 per cent to 42 per cent of SBS solution and 32 per cent to 44 per cent of No. 120 solvent gasoline. The production method is that the solid paraffin is first dissolved into water and then a screen mesh is adopted to remove the solid impurities; the gained pure liquid paraffin is mixed with the gasoline to stir evenly; then the SBS solution is added to stir fully and mixed evenly to gain the forming agent solution; the temperature of the forming agent solution is kept for use. The use methods of in-situ preparation, thermal insulation and short storage are adopted. The invention adopts the gasoline as solvent, which makes the paraffin and the SBS solution dissolved in the same solution system and makes the two play use of forming together with good forming performance. The carbon content remained is greatly reduced and high-carbon WC powder can be used as raw material to produce hard alloy. Meanwhile, because of low viscidity, the forming agent of the invention can not only suitable for manual adhesive-doped technology but also suitable for the preparation technology of the spray drying mixture.
