@songshunsteelsupply: Steel round bar is being rolled. Rolling is a metal processing technique that involves passing metal billets through the gaps (various shapes) of a pair of rotating rollers. Due to the compression of the rollers, the material cross-section is reduced and the length is increased, resulting in a pressure processing method. #Rolling #metalprocessing #metalprocessingtechnology #technology #metalblank #rollers #processing #tiktok #steel #steelmill #steelsupplier #steelsupply #steelmanufacturer #steelmanufacturers #steelworker #steelfactory #steelmills #steelmaking #Knowledge #Steel #steelmanufacturing #steelmill #Ingot #steelsuppliers
