Applications
Carbide rings have the following common uses due to their high hardness, high strength, wear resistance, and corrosion resistance:
- Mechanical processing: used as wire drawing dies to shape the wire and improve the surface quality when drawing metal wires; used as tool pads for tool blades to ensure cutting stability, and can also be used as drill sleeves to guide the drill bits for precise processing.
- Mold manufacturing: used as pressed parts of powder metallurgy molds to shape metal powders; also used as wear-resistant inserts and cores in rubber and plastic molds to extend the life of molds.
- Petrochemicals: important parts of drill bits for oil drilling (such as the bearing parts of roller drill bits), wear-resistant and impact-resistant, suitable for harsh drilling environments; also used as sealing rings and wear-resistant rings in chemical equipment to resist medium erosion and corrosion.
- Electronic information: In the manufacture of electronic components, such as the processing molds of some precision electronic parts, their high precision and wear resistance are used to ensure product quality and production efficiency.
