The Main Part Design of HC Rolling Mill
Abstract: Rolling equipment mainly refers to the completion of the raw materials to finished the whole rolling process used in machinery and equipment. The purpose of this process is to get required shape and specification of the steel. The cold-rolling is the major process of producing cold-rolled strip steels which are high value-added products and the necessary raw materials for automotive, construction, home appliances, food and some other industries.
The main part design of Hitachi High Crown Control mill covered in this paper is devised though a comprehensive consideration and a comparison of various options. The purpose of this topic is to design a kind of cold rolling mill which can improve the shape of the cold-rolled strip steels. The paper, at first, introduced the basic concept of steel rolling, steel rolling mill and HC rolling mill. Then it analyzed the purpose and objective of the topic. Finally, in detail, it introduced the calculation process of rolling force of 1450 single-frame reversible cold rolling mill, the choice as well as the design and calculation of roller adjustment device, screw down and screw nut, the rack strength and deformation of the cold rolling mill and some other parts of the cold rolling mill.
Key Words: cold rolling mill; rolling force; roller adjustment device; the rack
