NUMERICAL SIMULATION AND EXPERIMENTAL STUDY ON TEMPERATURE FIELD DURING CHEMICAL REAGENT COOLING PROCESS OF HOT ROLLED REBAR

A numerical simulation of phase transformation for hot-rolled strip on run-out-table are introduced in the present work combined with experiment. Continuous-cooling-transformation (CCT) diagram are used to regress the transformation model of Q345B. Temperature field coupled with phase transformation is analyzed on run-out-table. Evolution of temperature and organization during cooling are analyzed for the hot-rolled strip between the last stand of finishing mill and coiling. It is concluded that the transverse temperature has significant effect on the uniformity of phase transformation.

Important Basis

Plastic profiles produced by extrusion die are cooled down and calibrated by calibrators, so it is an important basis to solve design problems of calibrators that how to obtain the transient temperature field of cooling process of hot plastic profiles. Based on the analysis of heat transfer ways during the cooling process, computation model, initial and boundary conditions are studied deeply, and then ANSYS is applied to simulate the cooling process of plastic profiles. Lastly, the transient temperature field of the cooling process is gain. Results of the numerical simulation show that the temperature drops of functional blocks, main-walls and inner-ribs are reduced in order of priority. Based on the results, the cooling water channels can be adjusted in order to improve the distributing uniformity of temperature field. All this is effective to the calibrators’ design.
