Industrial Zirconia ceramic Cone Pulley/capstan pulley

Product Descri-ption

Specially formulated for wire drawing applications. This fine-grained zirconia ceramic

provides extreme Hardness, an exceptionally smooth wire drawing surface and

excellent corrosion resistance.

 

Hardness

Specially formulated, zirconia ceramic is the most man-made material for wear applications such as wire drawing capstans.

 

Corrosion Resistance

Specially formulated, zirconia ceramic is highly resistance to attack by corrosion problems(chemical contents used in processing of wire drawing).

The corrosion resistance fo zirconia ceramic is far superior to me-tal.

 

Surface Finish

The superior surface by high polish processing result in high quality of the drawn wire plus extended die life.

Originality Providing excellent hardness, corrosion resistance, superior surface finish, ceramic capstans attained worldwide estimation in wire drawing industries field.

  

Product Descri-ption In order to meet the needs  of high quality and productivity of me-tal wire drawing machines production,our company has successfully developed the ZrO2 ceramic wire drawing capstans with the strong technical supports from the relative university and research institutes.The ZrO2 ceramics is a type of new hi-tech  with the following advantages which  compared with traditional AI2O2 ceramics.

 

1.  High strength and fracture toughness

2.  High hardness and wear resistance

3.  its coefficient of thermal expansion almost attain the common me-tal

4. Low thermal conductivity Featured with high strength and fracture toughness,ZrO2 ceramics has been well known as the ceramics steel.

 

Its fracture toughness is the highest among all types of ceramics and its machining performances are excellent.with the perfection OF ZrO2v formula and those features guarantee their uncomparable wear-resistance with  the traditional ceramics.after machining,the fine grain ceramics can gain very low surface roughness(<0.1UM),thus improve the quality of the finished wire rods.The fine grain ZrO2 ceramics is capable of self-lubrication and better polish can be expected after service.
