Zirconia ceramic wire drawing wheel- A reliable alternative to traditional drawi

The ceramic wire drawing wheel is a key component of the wire drawing machine, a metal wire production equipment. The quality and stability of this product directly affect the quality and production efficiency of the metal wire produced.

Zirconium oxide ceramics have high strength and hardness. Compared with alumina ceramics, they are more reliable and have excellent wear resistance. It also has the characteristics of phase change toughening and microcrack toughening. Its fracture toughness is the highest among all ceramics and is known as "ceramic steel". The bending strength can reach more than 2000MPa, and the fracture toughness reaches 9Mpam1/2. It is suitable for wires, cables, and textile machinery. Zirconia ceramics have a high surface finish and self-lubricating effect. They are more wear-resistant than wire drawing wheels made of other materials, and their service life can be increased several times. The wires and tubes drawn out are burr-free and damage-free. They are high-tech products that replace traditional wire drawing wheels.

3y-tzp zirconia powder is usually selected as the main raw material, and then additives such as α-alumina, magnesium oxide, cerium oxide, praseodymium oxide, erbium oxide, ammonium metavanadate, and calcium dihydrogen phosphate are added to improve the material properties.

Molding method: First, the raw material is ball-milled into a slurry, and then made through spray granulation, isostatic pressing, turning, sintering into porcelain, and cold processing. Among them, the pressure of isostatic pressing is generally 200mpa, which can increase the strength of the green body for subsequent processing.

Sintering process: Sintering is a key step. A suitable sintering process can enable zirconia ceramics to obtain ideal microstructures and properties, such as fine-grained structure, thereby ensuring its high hardness, high strength, and good toughness.

Performance advantages

Good wear resistance: The hardness of zirconia ceramics is second only to diamond and is much greater than the hardness of metal and alloy materials. It can be used for wire drawing wheels to greatly increase its service life, rand educe wear and replacement frequency.

Good surface quality: Zirconia ceramics with fine grain structure can obtain very low surface roughness (<0.1μm) through processing, which can reduce the friction coefficient of the ceramic surface, thereby reducing friction, improving the quality of wire drawing, making the drawn wire smooth and burr-free, and not easy to break.

Self-lubrication: The elastic modulus and thermal expansion coefficient of zirconia ceramics are similar to those of steel, so they can be combined with steel parts to form a composite wire drawing wheel, which will not be damaged or exploded due to inconsistent thermal expansion, and its fine grain structure has a self-lubricating effect, and the wire will become smoother and smoother during drawing.

In summary, zirconia ceramic wire drawing wheels have shown strong competitiveness and broad application prospects in modern industrial production with their excellent material properties, unique structural design, advanced production technology, and significant performance advantages.
