Taguchi approach for optimization of process parameters in improving Quality of steel strip in single stand cold rolling Mill
Journal Title: American journal of Engineering Research - Year 2017, Vol 6, Issue 9
Abstract
Thickness variation is important Quality parameters of cold rolled steel strip in cold rolling Process. Various Process models for cold rolling mills have been intensively developed, hoping to increase quality of steel strip and productivity of rolling processes. The availability of robust & accurate models is associated for optimization has been intensely explored in the literature. There is not much research done on application of Taguchi based Method in single stand cold rolling mill for optimization of cold rolling process parameters. This paper focuses on application of Taguchi Approach in optimization of cold rolling process parameters of steel. The purpose of a cold rolling mill is to successively reduce the thickness of the metal strip and/or impart the desired mechanical and micro structural properties. Optimization for cold rolling mills rolling parameters are continuously being improved due to today's stringent high throughput, quality and low scrap loss requirements for products to make process robust. Ašæ27 orthogonal array was selected and total 27 experiments conducted in Single stand reversing cold rolling Mill after selecting control factors and its levels. After conducting experiment thickness variation measured and signal to noise ratio calculated. With help of graphs, optimum parameter values were obtained and confirmation test carried out.
