Rulers (3) hold billet (2) and grinding balls on the rolling axis. Helical streams (4) are cut into <a href=\"https:\/\/energosteel.com\/en\/library\/the-rolling-rolls\/\" target=\"_blank\" rel=\"noopener\">rolling rolls<\/a>. Helical streams formed by helical flanges (5). The height and width of the helical springs increases during rolling. The round billet is material for grinding balls rolling and has diameter slightly smaller than rolling ball.<\/p>\n<p style=\"text-indent: 20px;\" align=\"justify\">The rolling performed following way: the flange (5) grip the billet then rotated it and moved it along the rolling rolls gradually compressing the web (6) and formed the grinding ball (7). Grinding ball separates from the billet in end of forming section and protrudes from the calibrated gauge.<\/p>\n<p style=\"text-align: center;\"><img decoding=\"async\" class=\"size-full aligncenter\" src=\"https:\/\/energosteel.com\/wp-content\/uploads\/2017\/03\/20170302_en.jpg\" alt=\"\" \/><\/p>\n<p style=\"text-align: center;\"><strong>Picture1.
