The invention discloses a control method for a loop of a hot continuous rolling finishing mill group. The control method comprises the steps that rolling tension of an upstream rack of a throwing rack is increased before rolling; when a head is rolled, after a downstream rack of the throwing rack bites steel for a preset time, a loop angle of the throwing rack is increased to a first preset angle; when a tail part is rolled, after the upstream rack of the throwing rack throws steel, the loop angle of the throwing rack is reduced to a second preset angle; and when the tail part is rolled, after the downstream rack of the throwing rack throws steel, the loop angle of the throwing rack is reduced to the original position. According to the control method for the loop of the hot continuous rolling finishing mill group, on the basis that the cost is not increased, strip steel finish rolling scratches can be effectively avoided. The invention further provides a control device for the loop of the ...
