When using steel shot to remove rust and polish steel structure, choose larger steel shot for the following reasons:
Larger steel shot has greater kinetic energy and impact force, can more forcefully hit the rust layer and impurities, improve rust removal efficiency, and has better removal effect on thicker or more stubborn rust. In terms of polishing, larger steel shot can shape and flatten the surface faster, making the improvement of surface roughness more obvious. Moreover, larger steel shot wears relatively slowly during the processing process and has 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, rust removal and polishing requirements, and process conditions. Sometimes it may also be necessary to combine steel shots of different sizes to achieve a more ideal effect.
