Abstract

In a steel industry the sheets of metal are formed by hot rolling process i.e. the metal stock/ingots is passed through two or more pairs of rolls to reduce the thickness and to make the thickness uniform as per requirement while in metal sheet forming, the metal is heated about 1700°F which is near the recrystallization temperature of steel when the hot rolled sheet comes out from the roller. The water jet is sprinkling on the sheet to reduce the temperature of sheet, for that purpose the water pipe with nozzle welded on it is used but due to manual welding of the nozzles errors are introduced while aligning the nozzles with pipe axis which leads to rejection or rework of the whole assembly. To reduce the rework, we are going to design a system which helps to maintain perfect alignment of nozzles with pipe axis which helps to reduce the production time, reduce the rework and rejection of part, and cost per product is reduce.
