Problems solved by technology

[0003] However, in today’s tungsten powder carbonization process, the tungsten powder mixture in the carbonization furnace tends to cluster together locally, resulting in uneven heating inside and outside, and a small amount of tungsten powder or carbon powder monomer clusters, resulting in uneven mixing and greatly improving the carbonization effect. Reduced, eventually causing the quality of tungsten carbide to be greatly affected

Abstract

The invention discloses a tungsten powder carbonization device in tungsten carbide production and an implementation method of the tungsten powder carbonization device in tungsten carbide production. The tungsten powder carbonization device in tungsten carbide production comprises a rotating mechanism, a carbonization furnace and an auxiliary rotating mechanism, one end of the carbonization furnace is movably connected with the lower end of one side of the rotating mechanism, and the other end of the carbonization furnace is connected with one end of the auxiliary rotating mechanism. The tungsten powder carbonization furnace has the beneficial effects that a mixed tungsten powder raw material can move left and right back and forth while rotating in a carbonization furnace main body, so that the mixed tungsten powder raw material cannot aggregate, the heating and carbonization effects of the mixed tungsten powder raw material are more uniform, the carbonization effect of tungsten powder is improved, a sleeve ball is smoother in the rotating process, the rotating friction resistance is reduced, the service life of the device is prolonged, and tungsten powder and carbon powder are uniformly mixed in the tungsten powder carbonization process, so that the tungsten powder is carbonized and heated more uniformly, and the carbonization effect of the mixed tungsten powder raw material is further improved.

Description

technical field [0001] The invention relates to the technical field of tungsten carbide production, in particular to a tungsten powder carbonization device in tungsten carbide production and an implementation method thereof. Background technique [0002] Tungsten carbide is a compound composed of tungsten and carbon. It is a black hexagonal crystal with metallic luster, its hardness is similar to that of diamond, and it is a good conductor of electricity and heat. Tungsten carbide is insoluble in water, hydrochloric acid and sulfuric acid, and easily soluble in the mixed acid of nitric acid-hydrofluoric acid. Pure tungsten carbide is brittle, and if a small amount of titanium, cobalt and other metals are added, the brittleness can be reduced. Tungsten carbide used as steel cutting tools is often added with titanium carbide, tantalum carbide or their mixtures to improve antiknock ability. Tungsten carbide is chemically stable. Tungsten carbide powder is used in cemented c...
