ROT 냉각과정의 Strip 두께방향의 열전달 해석

A Integral Model for the Analysis of Strip Temperatures During ROT Cooling in Hot Strip Rolling

A finite element-based, integrated process model is presented for coupled analysis of the thermal and metallurgical behavior of the strip occurring on the run-out-table in hot strip rolling. The validity of the proposed model is examined through comparison with measurements. The models capability of revealing the effect of cooling pattern on strip temperatures and the optimal cooling pattern are demonstrated through a series of process simulation. In order to improve strip shape and control temperature history of thickness direction for strip during ROT cooling.
