Abstract

meios granulados fabricados de aço fundido usados para remoção de incrustação formada sobre uma superfície de um produto de metal através de tratamento de jateamento compreendem: um primeiro grupo sendo um grupo de meios granulados no qual um diâmetro de partícula d1 pertence a um primeiro segmento de diâmetro de partícula de d1max = d1 > d1min e tendo uma frequência máxima p1 no primeiro segmento de diâmetro de partícula; e um segundo grupo sendo um grupo de meios granulados onde um diâmetro de partícula d2 pertence a um segundo segmento de diâmetro de partícula de d2max = d2 > d2min e tendo uma frequência máxima p2 no segundo segmento de diâmetro de partícula, onde o primeiro grupo e o segundo grupo satisfazem relação de d1max = d2min, e uma distribuição de frequência de diâmetro de partícula dos meios granulados compostos pelo primeiro grupo e o segundo grupo é substancialmente contínua.Fabricated cast steel granular media used for scale removal formed on a surface of a metal product by blasting treatment comprises: a first group being a group of granular media in which a particle diameter d1 belongs to a first diameter segment particle size d1max = d1> d1min and having a maximum frequency p1 in the first particle diameter segment; and a second group being a group of granular media where a particle diameter d2 belongs to a second particle diameter segment of d2max = d2> d2min and having a maximum frequency p2 in the second particle diameter segment, where the first group is the second group satisfies d1max = d2min ratio, and a particle diameter frequency distribution of the granular media composed of the first group and the second group is substantially continuous.
