Steel Wrinkle Doctor Blade

Coating doctor blade is used in coating machine, assist in an important part of a paper production, doctor blade quality directly affect the product quality and production efficiency of paper.The rapid development of paper industry began to require better adapt doctor blade to the operation of the high-speed paper machine, not only ensure the quality of paper, and can improve production efficiency.

Wrinkle doctor blade is a special mechanical blade used in dryer section to assist paper production, and it is also a consumable in paper production.

Wrinkle doctor blade and dryer surface are contact, so doctor blade material is very important, to choose appropriate to protect the cylinder surface, scrape out a good wrinkle, the hardness of the wrinkle doctor blade is slightly lower than the surface of the dryer.Too large will damage the cylinder surface, too low, the blade is easy to roll mouth, can not scraping the paper.Below are several materials suitable for scraper, can achieve satisfactory use.

Material:

Steel wrinkle doctor blade: adopt import steel to improve service life and using effect.
High carbon steel wrinkle doctor blade: traditional wrinkle doctor blade with tempered,hardness HB220~229.
Ceramic coat steel wrinkle doctor blade: Suitable for high speed paper machine, choose import steel as the base material, use thermal spraying technology to spray ceramic coating on the blade edge surface.The groove design has the advantages of stable paper grain and light wear to dryer cylinder.
Tungsten carbide coat steel wrinkle doctor blade: imported steel coated scraper combined with thermal spraying technology, in the scraper blade spraying tungsten carbide coating, and then grinding processing.It has good wear resistance, long service life, high manufacturing accuracy and smooth surface, which can reduce the roughness of paper surface and improve the stability of paper quality.
