Nozzle Arrangement for Optimal Performance of Cooling Process of Run Out Table

Abstract

We numerically analyze the cooling process of a steel plate in a run out table (ROT). As a preliminary attempt to obtain the best cooling capacity in a facility with limited space (i.e., the length of the ROT), the number of nozzles representing the quantity of supplied cooling water, and the spacing between the nozzles, are changed for several cases without changing other factors. Thus, the effects of the nozzle arrangement on cooling performance are investigated. Cooling histories of the plate, the heat flux on the plate’s surface, shapes of the residual water distribution, and cooling capacity are obtained for various cases.
