Specially formulated for wire drawing applications. Thisfine-grained zirconia ceramic

provides extreme Hardness, an exceptionally smooth wire drawingsurface and

excellent corrosion resistance.

 

Hardness

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

Corrosion Resistance

Specially formulated, zirconia ceramic is highly resistance toattack by corrosion problems(chemical contents used in processingof wire drawing).

The corrosion resistance fo zirconia ceramic is far superior tometal.

Surface Finish

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

Originality

Providing excellent hardness, corrosion resistance, superiorsurface finish, ceramic capstans attained worldwide estimation inwire drawing industries field.

 

 

Product Description In order to meet the needs  of highquality and productivity of metal wire drawing machines production,our company has successfully developed the ZrO2 ceramic wiredrawing capstans with the strong technical supports from therelative university and research institutes.The ZrO2 ceramics is atype of new hi-tech  with the following advantages which compared with traditional AI2O2 ceramics.

1High strength and fracture toughness

2High hardness and wear resistance

3its coefficient of thermal expansion almost attain the commonmetal

 4Low thermal conductivity Featured with high strength andfracture toughness, ZrO2 ceramics has been well known as theceramics steel.Its fracture toughness is the highest among alltypes of ceramics and its machining performances are excellent.withthe perfection OF ZrO2v formula and those features guarantee theiruncomparable wear-resistance with  the traditionalceramics.after machining, the fine grain ceramics can gain very lowsurface roughness(<0.1UM), thus improve the quality of thefinished wire rods.The fine grain ZrO2 ceramics is capable ofself-lubrication and better polish can be expected afterservice.The modulus of elasticity and the coefficient of thermalexpansion of the ZrO2 ceramics are similar to those of the steel,making it available to form a compound wire rod drawing wheel withits steel parts.And the damages or cracks can be avoided because oftheir balanced thrmal expansion Practical use prove that the ZrO2ceramic wire drawing capstans are the perfect spare parts formodern high speed wire drawing machines.
