Abstract

The review of cold rolling mills used for the production of tinplate and thin tinplate in the world is presented. World tinplate production is characterized by the desire to reduce the thickness of its steel base. In connection with the variety of tinplate rolling mills, peculiarities of the deformation conditions of thin tinplate, complexity of the technological process and theoretical prediction of the rolling process indices, especially in terms of the theoretical model universality, as well as paucity of existing practical data, the necessity of experimental research is substantiated. Experimental research methodology of energy and force modes for tinplate and thin tinplate rolling for different cold rolling mills: five-, six- and seven-stand, was developed. Deformation modes have been developed that allow simulating the process of continuous cold rolling of tinplate with a thickness of 0.16 mm and 0.28 mm in five-, six- and sevenstand mills, respectively. The technical characteristics of industriallaboratory equipment involved in experimental research are presented. The results of the chemical composition and mechanical properties investigation of the initial blank are presented. Experimental research of energy and force modes for tinplate rolling at different parameters of cold rolling mills using the developed methodology will determine their optimal combination, as well as justify the choice of rolling equipment in terms of energy efficiency of the rolling process and the quality of the strip.
