Influence about the Cooling Pipe´s Inlet of Bars Pattern on the Cooling Effect

In this paper, the cooling process of Large-diameter bars is simulated by the 3D numerical simulation calculation method of Finite Element Coupling Field. Then, the influence, which about the controlled cooling inlet pattern on the cooling effect, has been analyzed. The results show that the bar cooling effect of annular nozzle inlet cooling pipe is the best among the several inlet patterns in this paper; relatively the bar cooling effect of four circular nozzles inlet cooling pipe is the worst among the several nozzles patterns in this paper. This numerical simulation result provides reference for choosing inlet pattern of bar controlled cooling equipment.
