The Technical Bottleneck of the Card Clothing with High Wear Resistance and the Breakthrough thereof

In order to solve the problem of the wear resistance and service life of the card clothing on the hi-speed and hi-production card,analysis is done to the the bottleneck of the development of the wear resistance card clothing regarding material quality,process,and design after the test and the research of the imported latest card clothing together with the progress of the metallurgy,material science and surface technology.It proves that the effective breakthrough includes the alloy optimization of the material,ultraifine grained steel,purgeing layer of decarburization,special surface treatment and special heat treatment.The high wear design that syncretize wear mechanism of card clothing,failure mode and decay track has innovative space and bigger prospective.
