A Study of the Effect of New Rolling Process on Strip Shape and Profile

The rolling parameters and their influences on thin metal strip rolling are addressed in this thesis by conducting various experiments and theoretical analyses using Matlab software. Thin carbon steel and aluminium strips are used for evaluating the influences of the cold rolling process parameters on the strip shape and profile. Throughout the thesis the shape and the profile of the thin low carbon steel and aluminium strips, and the microstructure and hardness effects of the thin low carbon steel strip are studied using newly developed strip shape control approaches. In the metal rolling industry, improvements need to be made to remain competitive in the market. Advancements need to be made in the manufacturing processes to increase productivity and produce better product quality. In this thesis, the strip shape and profile are probed for maintaining the dimensional accuracy due to the increasing applications of thinner strips. The thesis objective was achieved by adopting a quantitative experimental methodology. Extensive testing and data analyses were involved in this thesis. A Hille 100 rolling mill was used. Details about the equipment used, the experimental procedure, the data managing and analysis method, and techniques and obtained results are shown in detail...
