A high-power current control device is used to realize the sub-regional control of the electric field, thermal field and stress field of the plate/strip; at the same time, the movable supporting beam and tension sensor are used to test the working conditions of the plate/strips with different lengths and widths, to simulate the instantaneous synchronous entanglement process between different fields.

Abstract: The present invention provides a dynamic contact heat transfer simulation device for rolling heavy-load deformation zone. The device includes a control system, a data acquisition system, a pressure-adjustable fixed cold end, a rotating chuck, a temperature-adjustable heat-conducting rod and an speed-adjustable rotation hot end; the device utilizes the rotating chuck and the speed-adjustable rotating hot end to adjust the rotation speed in real time according to the actual rolling conditions, simulate the working conditions of the actual rolling heavy-load deformation zone, and accurately obtain the dynamic heat transfer coefficient of the rotating contact interface under variable load pressure conditions.
