| description | The invention relates to the technical field of screw machining, and discloses a fully-coated tungsten carbide production process which comprises the following steps: step 1, raw material preparation: mixing tungsten powder and carbon powder as raw materials; step 2, wet ball milling: the mixed raw materials and a proper amount of a ball milling medium are put into a ball mill together for wet ball milling, in the ball milling process, raw material particles are ground into finer powder, and the ball milling medium plays a role in mixing; and step 3, drying: drying the mixed powder obtained by wet ball milling so as to remove moisture. Through the wet ball milling and coating process, raw material powder can be more uniformly mixed, the coating agent can uniformly cover the surface of the powder, the uniformity and consistency of the product are improved, and through treatment such as ball milling and screening, the particle size of the tungsten carbide powder can be controlled so as to meet the requirements |
