Sheet rolling method

摘要

According to the invention, both sides of a sheet metal billet are worked with solid hard spherical microbodies prior to each reverse rolling operation. Microbodies are fed by means of a gas jet and have a diameter of 40 to 200 microns. They are of a material selected from the group consisting of glass, aluminum oxide, zirconium oxide, chrome-nickel alloys, and ice. The rolling produces a mirror or dull finish, an effect normally attained by etching, grinding or polishing.
