Comparison of Three Remedial Alternative Solutions' and Selection of Best for Alternative Design of Pressure Board UVSL

Time saved is time earned. This project deals with saving time of guide wood setting in cold rolling mill 2 in cold rolling mill complex at UTTAM VALUE STEELS LTD situated at Wardha In Maharashtra. Guide wood and side guide is an arrangement in cold rolling so as to provide back tension in 1st pass and strip centering in order to create straight winding In coil along proper shape. Existing system is simple but having a major drawback as it is consuming more time during width change. The existing systems consist of wooden pieces of two different sizes, one size for top and another for bottom setting. Both types of this guide wood s are clamped in set of various widths of coils to be rolled. Width of coils varies from 900mm to 1330 mm. every times the width change the setup of guideword need to be changed and thus delay is caused. guide wood setting is fully a manual process and is done by operator himself. as manual factor is involved there are maximum chances of error that may cause wastage of time and material as well. moreover the guide wood setting causes the disturbance of rhythm of production any error in guide wood setting results in false value of parameter necessary for rolling that may defect in output. The project works deal with various alternative for existing setup of guide wood their comparative study, analysis and selection of best alternative. Three possible alternative are studied one consist of three pairs of rolls kept over one another with gap between each set to allow inward and out ward movement of side guide rolls.2nd one consist of alternative arrangement of five rolls. The third arrangement is a little bit change in existing system. These three methods will be studied and best one will be selected so as to save time and labor.
