AI Technical Summary

Benefits of technology

This patented technology relates to making better quality glass panels and cutting members made from this type of metal called molybrons. These improvements include increasing their abrasion resistances, reducing cracks during use, enhancing its lifespan, adding extra layers like zirconia powder, silicon dioxynitride, copper oxide, tantaluminum, manganese sulfate, tin compounds, and others. By combining different types of metallics together, we have developed new compositions that improve upon existing ones while maintaining excellent properties over time.

Problems solved by technology

This patented technical problem addressed in this patents relates to selecting suitable material compositions for use during high pressure deliveries from different sources such as industrial pumps, pipeline systems, and hydraulic power plants. These materials have specific properties that make them difficult to break down over time without losing their effectiveness when subjected to severe shock conditions caused by hitting against other objects on site.

Embodiment Construction

[0010] Take the product YWF23 (brand) of the present invention of making spectacle plate and cutting ring as example:

[0011] Tungsten carbide with a carbon content of 6.10-6.18% (free carbon 2 ), the semi-finished product pressed by the press is sent to a vacuum furnace for sintering. The sintering furnace can be a vacuum furnace produced by Zhuzhou Cemented Carbide Factory. During sintering, an 80-180 mesh emery cloth is used to separate the semi-finished product from the boat. The sintering furnace requires a vacuum degree of about 30μ, an air leakage rate of <10μ in 1 minute, a sintering temperature of 1430°C-1460°C, and a holding time of 0.5-1.5 hours. After sintering, it is cooled out of the furnace, and the finished product is made.

[0012] Taking the production of conventional general-purpose blades as an example, tungsten carbide with a particle size of FSSS2-4, a total carbon of 6.10-6.16%, and 90% of the alloy content is selected as the hard phase, and iron and co...
