WORK ROLLS SURFACE TEXTURED BY MEDIA BLASTING AND CONTROLLED SURFACE MODIFICATION

摘要

Apparatus and methods of texturing the surfaces of work rolls and the rolls produced thereby which are used in the manufacture of sheet metals and other sheet materials. The working surface of each roll is textured in a series of process steps which include the steps of media blasting and controlled surface modification. Media blasting can precede or follow controlled surface modification and intervening process steps can be used. Either or both process steps of media blasting or controlled surface modification can be carried out once or more than once as long as each process step is used at least once. The work rolls produced by the method exhibit improved performance and extended life.
