Tungsten carbidedie tools classification:
The first type is tungsten carbidewire drawing dies, which are mainly used for tungsten carbidedies. At present, the main wire drawing dies YG8, YG6, YG3, followed by YG15, YG6X, YG3X, have developed some new brands, such as the new brand YL for high-speed wire drawing, and the number of imported wire drawing dies CS05 (YLO). 5), CG20 (YL20), CG40 (YL30); K10/19 date, ZK20/ZK30.
The second type of die tools is cold heading die tools and plastic die tools. The main brands are YC20C, YG20, YG15, CT35, YJT30 and MO15.
The third type of die tools is an amorphous alloy die tools for the production of magnetic materials, such as YSN (20, 25, 30, 35, 40) of the YSN series, and non-magnetic models of carbidestructure TMF.
Quality control of mixed production of tungsten carbidedie tools:
The mixed production process includes three processes: batching, wet grinding and spray drying. The so-called quality control of mixed material production is an effective control of several key parameters of these three operating procedures. The internal material quality control of cemented carbide is mainly to control the grain size of all carbon and alloy and the internal structure of the alloy. The external quality control of cemented carbide is mainly embodied in the control of the process performance of the mixture, that is, the fluidity of the material and the density of the loose filler. The current control focus is on mixing and mixing process; the latter's quality control focus is on spray drying process.
