the purpose of this project is to learn the use of different electrical machines particularly electrical motors and derives in manufacturing process of TMT bars which are manufactured in hot rolling mills.the electric derive system is the main part of manufacturing units.through this project i am able to know different types of motors used for different purposes and their control Thermo mechanically treated steel process uses a three phase induction motor for pushing ingots inside furnace with the help of conveyer rollers using worm gear pushing mechanism,after furnace exit the ingots are led into roughing mills with the help of a couple of single phase steeper motors coupled together, the roughing mill used a specially designed high capacity motor,in this mill there is very slight elongation and gradually decrease in diameter and this is the main function of roughing mill. there are three sets of rollers present in the roughing mill.the single motor shaft is transmitted to three shafts through the distributors.the roughing mills consists of different slots,the molten ingots passe
