The design of HC mill stick
Abstract: The rolling manufacture is an important role of making billet steel. There are several advantages of production of steel by rolling, such as high productivity, multi –species, strong continuity of the production process, easy to realize mechanization and automation etc. Therefore rolling is used much more than forging, extrusion and drawing process. Nowadays, Some 90% steel is produced by rolling process as well as nonferrous metal. HC mill is initiated by the Japan Hitachi Ltd., which is developed into HC series. The design principle is control shape by moving freely in axial direction of cylindrical middle stick or middle stick and working stick. This topic aims at the design of mill stick, a portion of rolling force calculation, stability calculation, roll strength calculation, bearing selection, and design and calculation of other major components.
Keywords: HC mill; mill stick; rolling force
