PURPOSE: A device for preventing upward movement of a material is provided to improve control performance by accurately measuring measurement data, such as temperature, thickness, width, and etc., about a material. CONSTITUTION: A device for preventing upward movement of a material comprises a first frame part, a first spray part, a first moving part, an electromagnet unit(50), and a control part. The first frame part is located above feed rollers which transfer a material discharged from a finishing mill. The first spray part is installed in the first frame part and sprays fluid to the material. The first moving part is provided in the first frame part and moves the first frame part from side to side in order to regulate the distance between the first spray part and the material. The electromagnet unit is located between the feed rollers and creates an electromagnetic force to correct the upward movement of the material. The control part controls the operations of the first spray part, the first moving part, and the electromagnet unit.
