CONCLUSIONSENGINEERING STUDENTS GAIN THEORETICAL KNOWLEDGE THROUGH BOOKS. IT IS VOLATILE AND NOT

OF MUCH USE WITHOUT KNOWING ITS PRACTICAL IMPLEMENTATION.

TRAINING IS ONE OF THE IMPORTANT ASPECTS FOR AN ENGINEERING STUDENT'S CARRIER TO

STRENGTHEN THE PRACTICAL CONCEPTS. IT WAS AN AWESOME EXPERIENCE IN TRAINING AS THE

THINGS WE ALL LEARNT IN OUR PREVIOUS YEAR WAS SEEN IMPLEMENTED PRACTICALLY. WE GOT TO

SEE THE LIVE PERFORMING EQUIPMENT LIKE BLAST FURNACE. HOT STRIP MILL( HRM), COLD ROLLING

MILL AND MANY MORE IN SAIL.
