Wheelabrator Skew Roll Machine Removes Rust, Scale
Cylindrical parts are conveyed through a blast machine on a specially designed skew roll-type material handling system.
Wheelabrator manufactures and installs standard and custom-designed blast systems for removing millscale and rust, and for profiling the surface of fabricated steel parts in preparation for protective coatings. According to the company, the Wheelabrator skew roll machine is a fully automated system designed to remove rust and scale from many cylindrical parts, including pipes, tubes, round bars, torsion bars, drill rods, rebars, gas cylinders and more. The machine is available with one, two or more blast wheels, depending on the application and cleaning rate.
Precision shot peening brings an entirely new concept to the field of microabrasive blasting, and it is complementary to its larger cousin. Using glass bead media, several companies have been shot peening for years with microabrasive blasting technology.
Metal fabricators that laser-cut with oxygen take steps to prepare parts better for powder coating.
Surface finish types for commercially supplied stainless steel sheet are detailed in various standards. ASTM A480-12 and EN10088-2 are two; BS 1449-2 (1983) is still available, although no longer active. These standards are very similar in that they define eight grades of surface finish for stainless steel. Grade 7 is “buff polished,” while the highest polish—the so-called mirror polish—is designated Grade 8
