Product Specification

1. Wear resistance and extended lifespan

Data comparison: The hardness of cemented carbide typically reaches HRA 89-92, which is more than 1.5 times that of hardened steel (HRC 58-62). In applications involving high-strength materials like steel and copper wires, ordinary steel wheels may develop wear marks within a few weeks or months. In contrast, cemented carbide wheels can last for many years, with their lifespan increasing by 10 to several dozen times compared to steel wheels.

Advantages: This significantly reduces the need for wheel replacements, thereby lowering costs associated with spare parts inventory and maintenance labor.

2. Stable wire surface quality

Scratch resistance: Cemented carbide wheels have a highly smooth surface (with a Ra value of less than 0.2) and extreme hardness, making them resistant to scratches caused by hard particles or oxide scales on the wires. The wear on the wheel grooves is minimal, allowing the wheels to maintain their precise geometric dimensions (diameter, R-angle) over time.

Advantages: This prevents defects such as scratches, burrs, and uneven surfaces on the wires. It is crucial for producing high-quality wires used in applications requiring smooth surfaces, such as enameled wires and precision welding wires.

3. High-temperature resistance and anti-seizing properties

Red hardness: Cemented carbide retains its high hardness even at temperatures between 500-800°C, whereas steel wheels become soft and ineffective at these temperatures. During high-speed drawing or drawing with high compression rates, heat is generated due to friction between the wheel grooves and the wires. However, cemented carbide wheels do not deform or wear excessively due to the increased temperature.

Anti-seizing: Cemented carbide has low affinity for metals like copper, aluminum, and steel, reducing the risk of “adhesive wear” – where metal from the wire adheres to the wheel grooves, causing damage to subsequent wires.

4. Corrosion resistance and rust prevention

Chemical inertness: Cemented carbide, especially those with lower cobalt content, is resistant to acid and alkali corrosion and does not rust.

Advantages: In wet drawing processes using emulsions or soaps, or in humid environments, steel wheels tend to rust, resulting in rough grooves. Cemented carbide wheels, however, maintain their smooth surface over time and do not contaminate the cooling fluid.

5. High overall economic efficiency

Although the initial cost of cemented carbide wheels is higher (about 5-10 times that of steel wheels), their long lifespan, low scrap rate, and reduced maintenance time result in lower total cost of ownership over the lifetime of the equipment.

**Application scenarios and considerations**

Suitable for: High-speed wire drawing machines, fine-drawing machines, sizing wheels, tension control wheels, and guide wheels in inverted winding machines. Also suitable for producing high-hardness, high-strength wires such as stainless steel wires, spring steel wires, tire cord steel, copper-clad steel, and alloy wires.

Not suitable for: Applications where cost is a critical factor and the surface quality of the wires is not a priority. This includes rough drawing processes with high compression rates, as these conditions can cause brittle fractures in cemented carbide wheels due to the high impact forces.

Disadvantages: Cemented carbide is brittle and has poor impact resistance. It must be handled with care to avoid damage. Additionally, it cannot be repaired like a steel wheel by reaming the grooves. Once a corner is damaged or cracked, the wheel must be replaced.
