What are the characteristics of the production of cemented carbide rods?

In the production and processing of cemented carbide rods, there is a link that determines the quality and the length of delivery. This link is the sintering link, which plays a decisive role in whether the quality of cemented carbide bars can be qualified.
After the tungsten carbide bar is produced and formed, it passes through an overpressure sintering furnace (600 kg per furnace), which has a fast production cycle and uniform overall performance. At the same time, our products will undergo some special processes and special ingredients; spray granulation, isostatic pressing, overpressure sintering, cryogenic treatment, etc., which can greatly improve the overall performance of the alloy.
The production of cemented carbide rods has the following characteristics:
1. Use fine tungsten carbide and imported cobalt powder as raw materials.
2. Adopt low-pressure sintering preparation technology for standardized production.
3. Has high strength and high hardness.
4. It has red hardness, good wear resistance, high elastic modulus, high bending strength, good chemical stability (acid resistance, alkali resistance, high temperature oxidation), good impact resistance toughness, low expansion coefficient, thermal conductivity, electrical conductivity and iron and its Alloy similar characteristics.
5. High-tech precision equipment: 10MPa low-pressure sintering furnace imported from Germany for sintering.
6. New process: Vacuum high temperature and high pressure sintering. The product adopts pressure sintering in the final stage to reduce porosity, improve compactness, and greatly improve the mechanical properties of the product.
7. Product features: There are many grades of materials, which can meet the needs of different uses; complete specifications, accurate blank size (reduce processing amount, improve production efficiency).
