This investigation is a holistic approach to analysis the process & its various aspects depend upon the viability& process reliability, of online process of structural plate steel heat treatment.
This work deals with the comparison of properties of micro-alloyed high tensile steel plates, obtained by using a on line process with offline process in plate mill of bhilai steel plant, without enriching its chemistry and without post heat treatment process generally called as normalizing rolling.
Online process: - This refers to a mechanical heat treatment process in which no need of post rolling heat treatment, such that the process need to control the temperature of the plate when rolled, results in improvement of mechanical properties & grain growth similar to normalized plate post rolling. So it enhances the less time manufacturing reducing production cost & increasing productivity.
Plate performance in terms of impact strength or toughness measured by impact Charpy test and in terms of ductility measured by bend test, the values of yield strength taken by performing test
