COMPARISON OF ROLL DEFORMATION IN 4HI ROLLING MILL AND 20 HI ROLLING MILL DUE TO THERMAL STRESSES, OVERLOADING, SPALLING AND DESIGN PARAMETERS

The Rolling mill roll deformation is a serious problem and directly impact on production capacity, Mill Environment, Quality and highly impacting financial viability of the production companies. In this research paper the data taken from three companies, Supreme Rolls and Shears Pvt Ltd Indore, Dee Tee Industries Indore, ASSIL Industires Jaipur and Ruchi Strips and Alloys Ltd Indore. The first two companies are producing rolls for other two companies. Second Company is having 4Hi Rolling and Third Company is having 20 Hi Rolling Mill. The Deformation analysis is strictly subjected to the Work Rolls. The deformation is done on four basic parameters like Thermal Stresses, Overloading, Spalling and Design faliures.
