There are usually some reasons for choosing larger steel shots when using steel shots for rust removal and polishing of steel structures:
Larger steel shots have greater kinetic energy and impact force, can more forcefully hit the rust layer and impurities, improve rust removal efficiency, and have better removal effects on thicker or more stubborn rust. In terms of polishing, larger steel shots can shape and flatten the surface faster, making the improvement of surface roughness more obvious. Moreover, larger steel shots wear relatively slowly during the processing process and have a longer service life, which also has certain advantages from an economic point of view.
Of course, this is not absolute. The specific choice also needs to be comprehensively considered and adjusted according to the specific situation of the steel structure, the requirements for rust removal and polishing, and the process conditions. Sometimes it may also be necessary to combine steel shots of different sizes to achieve a more ideal effect.
