Publisher:Tungsten carbide particles
The application of tungsten carbide particles have great significance for the production and processing of cemented carbide ，according to long-term production and processing experience,The tungsten carbide particles used in the production and processing of cemented carbide are determined according to their corresponding equipment requirements.Cemented carbide's requirements for tungsten carbide particle size and distribution.
1.The particle size of tungsten carbide powder is divided into ultra-fine, Asian, fine, medium and coarse particles;
2.Each kind of tungsten carbide requires evenly powder particle size and coarse sub-crystal size.
3.The tungsten carbide used in each alloy ,it requires a specific particle size distribution curve.
4.Tungsten carbide particle size measurement commonly used Fisher particle size analyzer to determine the average particle size, expressed in FSSS.
5.The grain size of tungsten carbide determines the properties of the alloy, not "grain size". The copper immersion method is usually used to determine the grain size of tungsten carbide.
For the production of cemented carbide, the use of tungsten carbide with different grain sizes will also have different uses, such as:
1、Cutting inserts, finishing alloys--Using ultra-fine, Asian, and fine-grained tungsten carbide.
2、Rough machining alloy---Using medium-grain tungsten carbide.
3、Gravity cutting alloy adopts medium and coarse grain tungsten carbide.
4、Mining tools and rocks with high hardness and large impact load-use coarse-grained tungsten carbide.
5、The rock hardness is small, the impact load is small-medium particle tungsten carbide is used.
6、Wear-resistant parts, when abrasion resistance, compression resistance and surface finish are required ---Ultra-fine, Asian, fine, and medium-grain tungsten carbide;
7、Impact resistant tools-Using medium and coarse-grained tungsten carbide as raw materials.
