Abstract

Abstract: In order to study the flow distribution characteristics of the slot cooling header after hot rolling, and the influence of different structure and technological parameters on the flow uniformity of outlet velocity and length direction was obtained. The three-dimensional steady-state numerical simulation analysis of the flow inside the manifold was carried out by FLUENT analysis software. The influences of inlet pressure, shape and structure of intermediate transition cavity were studied respectively. The results show that within the range of 0.1~ 0.5MPa of the inlet pressure, the velocity fluctuation in the direction of the outlet length increases with the increase of the pressure, and the width decreases from the middle of the gap to both sides. The flow velocity at the jet outlet can be increased by changing the angle of outflow tilt of the water supply pipe.
