Abstract

    As national economic base, iron and steel industry plays a very important role in national economy. As far as the production of iron and steel is concerned, the rolling mill is the main tool. Its performance and develop has a decisional significance to the development ability and advancing extent of iron and steel industry. This paper will, based on the basic theory of cold rolling mill, with the combination of a scientific research—“the research and development of a virtual six-roller reversible cold rolling mill”. It is from the project of CISDI and Chongqing University, mainly focused on the optimizing design of rollers of rolling mill.
The main contents: source and background of the subject; general introduction of rolling mill; types of rolling mill; development state of rolling mill home and abroad; general introduction of rolling mill’s structure; working principles; major features of mill’s structure; introduction of rollers; rolling force energy parameters; basic knowledge of rolling principle; rules formulation of mill; calculation of rolling force energy parameters; optimizing design of mill rollers and model calculation of roller bearing; optimizing design of mill roller; determination of design variables; selection of roller bearing. In this paper, it will apply material mechanics, theoretical mechanics, rolling machinery, rolling principles etc.

Key words: rolling mill　 roll　 six-roll
