Materials and methods for surface treatment of metal products using such pellets.

Abstract

Page 1 of 1 Summary of the invention. Cast iron ball media is used for removing scale buildup on surfaces. Metal products manufactured by spraying include: the first group, which is the intermediate group of pellets, The particle diameter d1 is in the segment where the first particle diameter d1max (symbol) d1 > d1min. And the one with the highest frequency, P1, is the first particle diameter sequence; and the second group, which is the second group. A blast medium in which particle diameter d2 is in a segment of particle diameter two. d2max(symbol)d2>d2min and the segment with the highest frequency P2 is the segment with the second particle diameter, The first and second groups are based on the relationship d1max=d2min, and the frequency distribution of the diameter line. The particle centers of the pellet medium, consisting of the first and second groups, can be considered to be continuous.
